Description

FIELD OF THE INVENTION

This invention relates to waterproofing and wood preservation compositions. Polyhydroxyl or polyether hydroxyl esters of fatty acids and polyether hydroxides have been found to be useful as waterproofers for wood substrates. Furthermore, these waterproofers in combination with quaternary ammonium compositions and a solvent are useful as waterproofing wood preservation compositions. Preferred quaternary ammonium composition include C.sub.1 -C.sub.20 alkyl or aryl-substituted alkyl, C.sub.8 -C.sub.20 alkyl quaternary ammonium chlorides, hydroxides, carbonates, carboxylates, or borates.

BACKGROUND OF THE INVENTION

Quaternary ammonium compounds (quats) and particularly didecyldimethylammonium chloride (DDAC) ##STR1## are commonly used as wood preservatives because they possess resistance properties to fungi and termites, to loss of strength, and to electrical sensitivity similar to those of commonly used acidic copper/chromium/arsenic solution (CCA) or ammoniacal copper and arsenic salt solution preservatives. See Proc of the Am. Wood Pres. Assoc., 80: 191-210 (1984). Although chloride quats do not include potentially dangerous heavy metals, didecyldimethylammonium chloride leaches rapidly in soil (Nicholas et al., Forest Prod. J., 41: 41 (1991), and therefore, does require coupling with copper salt.

Findlay et al., U.S. Pat. No. 4,929,454, disclose a method of preserving wood by impregnation with a quaternary ammonium compound and at least one of zinc and copper, wherein the quat anion is chosen from the group consisting of hydroxide, chloride, bromide, nitrate, bisulfate, acetate, bicarbonate, and carbonate, formate, borate and fatty acids. These quats have distinct environmental and safety advantages over commonly used acidic copper/chromium/arsenic solution (CCA) or ammoniacal copper and arsenic salt solution preservatives in that potentially dangerous heavy metals are not included. The Findlay et al. quats require copper or zinc in order to render them relatively insoluble and to prevent them from leaching out of a treated substrate. The use of copper or zinc in the above formulations may yet raise environmental and corrosion concerns.

Additionally, didecyldimethylammonium chloride tends to absorb preferentially to the surface of the wood and does not uniformly treat the whole substrate. Finally, DDAC treated wood shows surface erosion or ages upon exposure to light. See Preston et al., Proc. Am. Wood Pres. Assoc., 83: 331 (1987).

The biocidal activities of various chloride quats against bacteria, fungi, and algae are tabulated in Cationic Surfactants, E. Jungerman Ed., pp. 56-57, Marcel Dekker, Inc., 1969. Nicholas, "Interaction of Preservatives with Wood," Chemistry of Solid Wood, Advance in Chemistry Series #207, Powell ed., (A.C.S. 1984) notes that didecyldimethyl ammonium compounds and particularly DDAC are potential biocides. Preston, J.A.O.C.S. 60: 567 (1983) concurs and suggests that maximum fungitoxicity is exhibited with dialkyldimethyl compounds having C.sub.10 -C.sub.12 alkyl groups. Butcher et al., Chem Abstracts No. 91: 152627b, suggests that the presence of an acid or a base can affect the activity of didecyldimethyl-ammonium quats.

Didecyldimethylammonium acetate was used as a phase transfer catalyst for an oxidation in Chem Abstracts No. 97: 9175. A wood preservative was prepared by autoclaving didecylmethylamine with gluconic acid and ethylene oxide in isopropanol to yield (C.sub.10 H.sub.21).sub.2 CH.sub.3 N ((CH.sub.2).sub.2 O).sup.+ gluconate in Chem Abstracts No. 109: 124403x, while disinfectant solutions were prepared by exchanging a benzylammonium chloride with a chlorhexidene gluconate in Chem Abstracts No. 103: 109954f.

Biocidal compositions which include quaternary ammonium compounds of the formula R.sup.1 N.sup.+ R.sup.2 R.sup.3 R.sup.4 X.sup.-, wherein at least one of R.sup.1, R.sup.2, or R.sup.3 is a C.sub.8 -C.sub.30 alkyl or alkenyl group and the remainder of R.sup.1, R.sup.2 or R.sup.3 is methyl, ethyl, CH.sub.2 Ph or 4-pyridylmethyl; R.sup.4 is methyl or ethyl; and X is an anion of an acid having a C.sub.7 or greater hydrophobic group, were disclosed in Chem Abstracts Nos. 113:154360f and 113:153776j. Chem Abstracts No. 112:79768u discloses compounds of the formula R.sup.1 R.sup.2 R.sup.3 R.sup.4 N.sup.+ X.sup.-, wherein R.sup.1, R.sup.2, and R.sup.3 are methyl, ethyl, benzoyl, 4-pyridinomethyl and at least one is C.sub.8 -C.sub.30 alkyl or alkenyl; R.sup.4 is methyl or ethyl; and X is a counter anion of acids having C.sub.7 or greater hydrophobic groups. Dimethyldidecylammonium dodecylbenzenesulfonate was demonstrated to impart long term rot resistance to wood without causing rust, while the chloride salts of similar compounds were demonstrated to cause rust.

Patton et al., U.S. Pat. No. 5,004,760, disclose polymeric foams incorporating various dialkyldimethylammonium carboxylates such as didecyldimethylammonium poly(ethylene/acetate) and the like.

Quaternary ammonium compounds (quats) are typically prepared by the reaction:

R.sup.1 R.sup.2 R.sup.3 N+R.sup.4 X.fwdarw.R.sup.1 R.sup.2 R.sup.3 R.sup.4 NX (II) wherein X is a halogen, a sulfate, a sulfo compound, or the like. When at least one of R.sup.1, R.sup.2, R.sup.3, or R.sup.4 is C.sub.12 or longer, the product is an inert soap. Many of the inert soaps have biocidal activity against bacteria, fungi, algae, and related organisms.

Reaction (II) above is limited by the reactant R.sup.4 X because R.sup.4 must react with tertiary amines. For example, methyl chloride (R.sup.4 X=CH.sub.3 Cl) will react with a tertiary amine at less than 100.degree. C. to yield a quaternary compound R.sub.3 N.sup.+ CH.sub.3 Cl.sup.-, while methanol or methyl acetate (R.sup.4 X=CH.sub.3 OH or CH.sub.3 COOCH.sub.3) will not, under similar reaction conditions.

General quaternary ammonium compounds with a sulfo group are easily prepared either by the reaction of a sulfate compound with a tertiary amine (III) or by a double exchange (IV).

If trimethylamine is heated with carbon dioxide and methanol above 200.degree. C. and at 85 to 95 atmospheres, the carbonate quat, bis-tetramethylammonium carbonate, is prepared. Industrial Organic Nitrogen Compounds, Astle Ed. p 66, Reinhold Inc, 1961. However, this reaction is limited to the methyl compound because higher homologs decompose to olefins by the Hofman elimination reaction. See, Organic Reactions, 11, Chptr. 5, 377, Krieger Publishing Co., 1975.

Chem Abst. 110: 212114 (1989) suggests that dimethyl carbonate will react with triethylamine in methanol in twelve hours at 115.degree. C. and under pressure to yield a methyl carbonate ester quat.

Chem Abst. 114: 24824 (1991) discloses that 6-hydroxy- or hexyl-dimethylamine reacts with dimethyl carbonate to yield a carbonate ester quat.

Quaternary ammonium hydroxides (hydroxy quats), an intermediate in the reaction scheme of the present invention, are currently prepared by the reaction of quaternary ammonium iodide with silver oxide (V).

RN.sup.+ (CH.sub.3).sub.3 I.sup.- +AgO.fwdarw.RN.sup.+ (CH.sub.3).sub.3 OH.sup.- +AgI (V) However, this reaction is costly, and it is difficult to recover the silver reagent. See, Organic Reactions, 11: Chptr 5, pp. 376-377, Krieger Publishing Co., 1975.

In an olefin synthesis, it has been suggested to treat a quaternary salt with aqueous sodium or potassium followed by pyrolysis in order to form the hydroxy quat and then to decompose the hydroxy quat directly. However, in this method the hydroxy quat is not isolated and the conditions for its preparation are undesirable. See, Organic Reactions, 11: Chptr 5, pp. 376-377, Krieger Publishing Co., 1975.

Talmon et al., Science, 221, 1047 (1983), have used an ion exchange resin to convert didecyldimethylammonium bromide to didecyldimethylammonium hydroxide (VI).

Talmon et al. state that the hydroxy quat can be reacted with acids to make quats with different anions, and they have prepared didodecyldimethylammonium (DDDA) acetate, DDDA-formate, DDDA-propionate, DDDA-butyrate, DDDA-oxalate, DDDA-acrylate, DDDA-tartrate, DDDA-benzoate, and DDDA-octanoate. See also, Organic Synthesis, Collective Volume VI, 552, John Wiley Inc., 1988; Brady et al., J. Am. Chem. Soc., 106: 4280-4282, 1984; Brady et al., J. Phys. Chem., 90: 9, 1853-1859, 1986; Miller et al., J. Phys. Chem, 91: 1, 323-325, 1989; Radlinske et al., Colloids and Surfaces, 46: 213-230, 1990.

Distearyldimethylammonium gluconate was prepared via ion exchange and subsequent reaction with an organic acid in Chem Abstracts No. 75: 119170U. Miller et al, Langmuir, 4: 1363 (1988) prepared ditetradecyldimethylammonium acetate by ion exchange from a bromide.

Alternatively, quaternary ammonium hydroxide compositions have been prepared by treating a haloquat in an electro-chemical cell with special cation exchange diaphragms between the cells. The hydroxy quat collects at one electrode, and the halide collects at the other. Hydroxy quats, R.sup.1 R.sup.2 R.sup.3 R.sup.4 N.sup.+ OH.sup.-, wherein the R groups were C.sub.1 -C.sub.4, were treated with carboxylic acids to make asymmetric quats that were used as capacitor driving electrolytes. See, Japanese Patent Publication No. 02-106,915 and Awata et al., Chemistry. Letters, 371 (1985). Awata et al. placed carboxylic acids in the cathode cell to react with tetraethylammonium hydroxide as it was formed.

Japanese Patent Publication No. 01-272-363 discloses the preparation of relatively low yields of tetraethylammonium hydroxide by reacting triethylamine with diethyl sulfate, heating the resultant quat with sulfuric acid to yield the sulfate quat, and reacting the sulfate quat with barium hydroxide to yield the short chain quat, tetraethylammonium hydroxide, and barium sulfate.

Di C.sub.8 -C.sub.12 alkyl quaternary ammonium hydroxides prepared by ion exchange were used as strong bases to digest animal tissue by Bush et al., French Patent Publication No. 1,518,427.

Akzo discloses that the addition of a metallic hydroxide to a quaternary ammonium chloride such as didecyldimethylammonium chloride, in an aqueous medium, results in an equilibrium mixture of quaternary ammonium chloride and quaternary ammonium hydroxide (VI). This reaction can be driven to the right by the use of isopropanol as a solvent.

Akzo further discloses that the addition of a soap to a quaternary ammonium chloride yields a quaternary ammonium carboxylate (VII).

Jordan et al., U.S. Pat. No. 3,281,458, disclose the preparation of dioctadecyldimethylammonium humate, ditallowdimethylammonium humate, dipentadecyldimethylammonium humate, and didodecyldimethylammonium humate by reacting humic acid, lignite, aqueous sodium hydroxide and a chloride quat.

Finally, Nakama et al., J.A.C.O.S., 67: 717 (1990) report the interaction between anionic and cationic surfactant and particularly sodium laureate and stearyltrimethylammonium chloride, while Linderborg, U.S. Pat. No. 4,585,795, disclose the use of synergistic mixtures of the alkali metal salt of certain biocidal organic acids, quaternary ammonium chlorides, and alkyl-pyridinium chlorides as control agents for short-term protection of timber against sapstain fungi and mildew.

Typically, quaternary ammonium compounds migrate or leach from wood under wet conditions, however. Common waterproofing compositions have not proven compatible with the quaternary ammonium compounds typically used in the industry, and therefore, they are not commonly used to hinder the leaching of these quats.

Typical waterproofers are waxes, lower molecular weight polyolefins, or dispersions or solutions thereof in hydrocarbon solvents. However, quaternary compositions, including those useful in the present invention, typically are water soluble. Generally, they are not soluble in these typical waterproofer solvent systems and are not compatible with emulsified or dispersed waterproofers.

It has now been discovered that C.sub.1 -C.sub.20 alkyl or aryl-substituted alkyl, C.sub.8 -C.sub.20 alkyl, and particularly di C.sub.8 -C.sub.12 alkyl, quaternary ammonium hydroxides, carbonates, carboxylates, and borates including those prepared by the methods described herein, are compatible with newly discovered polyhydroxyl or polyetherhydroxyl esters of fatty acids or polyether hydroxide waterproofers. Waterproofing and wood preservative systems prepared from the waterproofers or waterproofers and quats described herein exhibit enhanced resistance to leaching and meet waterproofing standards for heavy duty, ground, or millwork applications.

DETAILED DESCRIPTION OF THE INVENTION

I. Waterproofers

The polyhydroxyl or polyether hydroxyl fatty acid ester or the polyether hydroxide waterproofers of the present invention are soluble in both aqueous and organic solvent systems. Furthermore, they render the water-soluble quats described herein useful in aqueous or organic systems as well. This occurs despite the fact that these quats alone, i.e. without the present waterproofers, are relatively insoluble in organic solvents, emulsions or dispersions., i.e. they are not generally useful in preserving wood when in an organic solvent.

The waterproofers of the present invention include compositions of the formula: ##STR16## wherein: X is hydrogen or ##STR17## R and R.sup.2 independently are a saturated or unsaturated, substituted or unsubstituted, interrupted or uninterrupted C.sub.9 -C.sub.50 group;

Saturated C.sub.9 -C.sub.50 groups include C.sub.9 -C.sub.50 straight chain, branched, or cycloalkyl groups. Unsaturated C.sub.9 -C.sub.50 groups include those groups having one or more double or triple bonds or combinations thereof including acyclic groups (including straight chain or branched), cyclic groups, or combinations thereof. In combinations, unsaturation may occur in the cyclic portion, the acyclic portion, or both. Substituted R or R.sup.2 groups can be substituted with one or more saturated or unsaturated carbon groups with the proviso that the total number of carbon atoms in the R or R.sup.2 group ranges from 9 to 50. These substitutions can give rise to cyclic R or R.sup.2 groups substituted with straight chain or branched, saturated or unsaturated acyclic groups and acyclic R or R.sup.2 groups substituted with saturated or unsaturated cyclic groups. Substituted R or R.sup.2 groups can alternatively or additionally be substituted with one or more oxygen or boron atoms or sulfate groups. Interrupted groups are interrupted by one or more oxygen or boron atoms or sulfate groups.

Waterproofers also include compositions of the formula ##STR19## wherein: X is hydrogen or ##STR20## Y is substituted or unsubstituted ##STR21## substituted or unsubstituted ##STR22## or an enantiomer thereof, or substituted or unsubstituted ##STR23## or an enantiomer thereof wherein R.sup.3, R.sup.4, and R.sup.5 independently are a saturated or unsaturated, substituted or unsubstituted, interrupted or uninterrupted C.sub.9 -C.sub.50 group; w is an integer from 1 to 10; and x and y are 0, 1, or 2.

Y groups can be substituted with one or more C.sub.1 -C.sub.9 groups with the proviso that the number of carbon atoms in the Y group ranges from 3 to 12, one or more oxygen or boron atoms or sulfate groups or any combination thereof, and can be interrupted by one or more oxygen or boron atoms or sulfate groups.

Saturated C.sub.9 -C.sub.50 groups include C.sub.9 -C.sub.50 straight chain, branched, or cycloalkyl groups. Unsaturated C.sub.9-C.sub.50 groups include those groups having one or more double or triple bonds or combinations thereof including acyclic groups (including straight chain or branched), cyclic groups, or combinations thereof unsaturated groups. In combinations, unsaturation may occur in the cyclic portion, the acyclic portion, or both. Substituted R.sup.3, R.sup.4, or R.sup.5 groups can be substituted with one or ore saturated or unsaturated carbon groups with the proviso hat the total number of carbon atoms in the R.sup.3, R.sup.4, or R.sup.5 group ranges from 9 to 50. These substitutions can give rise to cyclic R.sup.3, R.sup.4, or R.sup.5 groups substituted with straight chain or branched, saturated or unsaturated groups and acyclic R.sup.3, R.sup.4 or R.sup.5 groups substituted with saturated or unsaturated cyclic groups. Substituted R.sup.3, R.sup.4, or R.sup.5 groups can alternatively or additionally be substituted with one or more oxygen or boron atoms or sulfate groups. Interrupted groups are interrupted with one or more oxygen or boron atoms or sulfate groups.

Saturated C.sub.6 -C.sub.30 groups include C.sub.6 -C.sub.30 straight chain, branched, or cycloalkyl groups. Unsaturated C.sub.6 -C.sub.30 groups include those groups having one or more double or triple bonds or combinations thereof including acyclic groups (including straight chain or branched), cyclic groups, or combinations thereof unsaturated groups. In combinations, unsaturation may occur in the cyclic portion, the acyclic portion, or both. Substituted R.sup.6 groups can be substituted with one or more saturated or unsaturated carbon groups with the proviso that the total number of carbon atoms in the R.sup.6 group ranges from 6 to 30. These substitutions can give rise to cyclic R.sup.6 groups substituted with straight chain or branched, saturated or unsaturated acyclic groups and acyclic R.sup.6 groups substituted with saturated or unsaturated cyclic groups. Substituted R.sup.6 groups can alternatively or additionally be substituted with one or more oxygen or boron atoms or sulfate groups.

Special mention is made of compositions where R.sup.6 is either p-nonylphenyl or C,, alkyl, and p is 4.

Also contemplated by the present invention are combinations of any of the above waterproofers.

These waterproofers hinder migration of the quat molecules from a substrate under wet conditions. Furthermore, where surface corrosion problems are related to the water holding properties of the quat, the waterproofer displaces or prevents the entry of water.

II. Quaternary Ammonium Composition Component

A. Quaternary Ammonium Hydroxide

Although any quaternary ammonium hydroxides are suitable for use in the present invention, quaternary ammonium hydroxides (hydroxy quats) having the formula ##STR30## wherein R.sup.7 is a C.sub.1 -C.sub.20 alkyl or aryl-substituted alkyl group, R.sup.8 is a C.sub.8 -C.sub.20 alkyl group, and preferably R.sup.7 is the same as R.sup.8 and R.sup.7 is a C.sub.8 -C.sub.12 alkyl group, are preferred.

Special mention is made of hydroxy quats wherein R.sup.7 is a methyl, C.sub.8 alkyl, C.sub.9 isoalkyl, C.sub.10 alkyl, C.sub.12 alkyl, C.sub.14 alkyl, C.sub.16 alkyl, or benzyl group; and R.sup.8 is a C.sub.10 alkyl, C.sub.12, C.sub.14 alkyl or C.sub.16 alkyl group. Most preferred hydroxy quats are didecyldimethylammonium hydroxide wherein R.sup.7 and R.sup.8 are a C.sub.10 alkyl group and most preferably an n-C.sub.10 group.

Didecyldimethylammonium hydroxide, when observed in a 70 to 80 percent by weight solution in a 50 percent by weight alcohol/50 percent by weight water solvent, is a yellow/orange liquid. This formulation has a flash point of about 134.degree. F., and it is a highly alkaline material that reacts with the phenolic OH of lignin.

Quaternary ammonium hydroxides useful in the present invention are preferably prepared according to the reaction illustrated below. ##STR31## wherein R.sup.7 is a C.sub.1 -C.sub.20 alkyl or aryl-substituted alkyl group; R.sup.8 is a C.sub.8 -C.sub.20 alkyl group; R.sup.10 is a straight chain C.sub.1 -C.sub.4 alkyl group; M is a mono-, di-, or trivalent metal; and m is one if M is monovalent, two if M is divalent, and three if M is trivalent. Preferably R.sup.7 is the same as R.sup.8, i.e. a C.sub.8 -C.sub.12 alkyl group.

Many C.sub.1 -C.sub.20 alkyl or aryl-substituted alkyl, C.sub.8 -C.sub.20 alkyl quaternary ammonium chlorides are suitable reactants, but di C.sub.8 -C.sub.12 alkyl quaternary ammonium chloride is preferred, and didecyldimethylammonium chloride, and particularly, di-n-decyldimethylammonium chloride is most preferred. The selections of the R.sup.7 and R.sup.8 substituents of the chloride quat reactant are determinative of the hydroxy quat product.

Special mention is also made of processes wherein R.sup.7 is a methyl, butyl, C.sub.8 alkyl, C.sub.9 isoalkyl, C.sub.10 alkyl, C.sub.12 alkyl, C.sub.14 alkyl or benzyl group; and R.sup.8 is a C.sub.10 alkyl, C.sub.12 alkyl, C.sub.14 alkyl or C.sub.16 alkyl group.

The metal hydroxide reactant is a mono-, bi-, or trivalent metal hydroxide, preferably a monovalent metal hydroxide, and most preferably an alkali metal hydroxide such as sodium hydroxide or potassium hydroxide. Special mention is made of potassium hydroxide. The metal chloride reaction product will precipitate and is easily removed, i.e. by filtration or the like, yielding a hydroxy quat/solvent reaction product. The hydroxy quat can be separated therefrom by drying or the like.

The reaction is conducted in a solvent which comprises a C.sub.1 -C.sub.4 normal alcohol. Preferably, the solvent is ethanol, and most preferably, anhydrous ethanol.

The amount of metal hydroxide reactant typically is a stoichiometric amount with respect to the quaternary ammonium chloride reactant. Therefore, on a theoretical basis and if the reaction were complete and unequilibrated, there would be no excess of metal hydroxide reactant upon completion of the reaction. In practice, yield when using a stoichiometric amount of metal hydroxide reactant will range from about 65% to about 95%, but will vary, dependent in part upon the particular metal hydroxide reactant.

Yield can be further improved over conventional methods by utilization of a stoichiometric excess of metal hydroxide ranging from about 2% to about 20% excess. If an excess of metal hydroxide is used, yield will be increased to from about 95% to about 99%, again varying as above.

The unreacted metal hydroxide is soluble in the hydroxy quat/solvent mixture. Any excess or unreacted metal hydroxide should be removed after the reaction is completed, and is preferably precipitated by subsequent reaction with carbon dioxide to yield the corresponding metal carbonate. The carbonate is insoluble in the hydroxy quat/solvent mixture and is easily removed, i.e. by filtration or the like. Alternatively, a solid metal bicarbonate, in which the metal corresponds to the metal of the metal hydroxide, can be added and slurried with the hydroxy quat/solvent mixture. The soluble metal hydroxide reacts with solid bicarbonate to yield the insoluble metal carbonate. The metal carbonate does not react further with the hydroxy quat.

Mixing, adding, and reacting of the components in the preparation of these hydroxy quats can be accomplished by conventional means known to those of ordinary skill in the art. The order of addition of reactants or solvent does not affect the process. Reactants and/or solvent can be added sequentially or simultaneously in any suitable reaction vessel.

Typically, the reactants and solvent will be stirred and heated to from about 20.degree. C. to about 70.degree. C. and held at that temperature for a period of from about 1 hour to about 5 hours. The reaction mixture is then cooled, first to room temperature and then to about 0.degree. C. where it is held for about 1 hour to about 2 hours. Any precipitated metal chloride is collected as is known in the art, i.e. such as by filtration.

Alternatively, the reactants and solvent can be stirred at a slightly elevated temperature, i.e. from about 20.degree. C. to about 40.degree. C., to yield the hydroxy quat/solvent mixture. Hydroxy quat can be separated as above.

B. Quaternary Ammonium Carbonate

Although any quaternary ammonium carbonates are suitable for use in the present invention, preferred carbonate quats have the formula ##STR32## wherein R.sup.7 is a C.sub.1 -C.sub.20 alkyl or aryl-substituted alkyl group, R.sup.8 is a C.sub.8 -C.sub.20 alkyl group, and preferably R.sup.7 and R.sup.8 are the same C.sub.8 -C.sub.12 alkyl group.

Special mention is made of carbonate quats wherein R.sup.7 is a methyl, C.sub.8 alkyl, C.sub.9 isoalkyl, C.sub.10 alkyl, C.sub.12 alkyl, C.sub.14 alkyl, C.sub.16 alkyl, or benzyl group; and R.sup.8 is a C.sub.10 alkyl, C.sub.12 alkyl, C.sub.14 alkyl, or C.sub.16 alkyl group.

Most preferred carbonate quats are didecyldimethylammonium carbonate wherein R.sup.7 and R.sup.8 are a C.sub.10 alkyl group and preferably an n-C.sub.10 alkyl group. Didecyldimethylammonium carbonate, when observed as a 70-80 percent by weight solution is a yellow/orange liquid that has a slightly fruity odor. This formulation has a flash point of about 160.degree. F, and it reacts with carboxyl containing compounds.

One or more of these carbonate quats alone or in combination with the corresponding bicarbonate quat(s) and/or metal carbonate salt(s), preferably potassium carbonate salt, can be formulated in the present waterproofer, wood preservative systems.

Although certain carbonate quats can be prepared by a variety of methods, preferably, the carbonate quats used in the present invention are prepared by an indirect synthesis method. ##STR33## wherein R.sup.7 is a C.sub.1 -C.sub.20 alkyl or aryl-substituted alkyl group; R.sup.8 is a C.sub.8 -C.sub.20 alkyl group; and preferably R.sup.7 is the same as R.sup.8 and R.sup.7 is a C.sub.8 -C.sub.12 alkyl group; R.sup.10 is a straight chain C.sub.1 -C.sub.4 alkyl group; M is a mono-, bi-, tri-valent metal, preferably a mono-valent metal, and most preferably an alkali metal; and m is 1 if M is mono-valent, 2 if M is di-valent, and 3 if M is tri-valent.

A C.sub.1 -C.sub.20 alkyl or aryl-substituted alkyl, C.sub.8 -C.sub.20 alkyl, and preferably a di C.sub.8 -C.sub.12 alkyl, quaternary ammonium chloride is used as a starting material and is reacted with a metal hydroxide to yield a C.sub.1 -C.sub.20 alkyl or aryl-substituted alkyl, C.sub.8 -C.sub.20 alkyl, and preferably a di C.sub.8 -C.sub.12 alkyl, quaternary ammonium hydroxide intermediate. The hydroxy quat intermediate(s) and any excess metal hydroxide are then reacted with carbon dioxide to yield the carbonate quat(s) and the metal carbonate.

Many di C.sub.8 -C.sub.12 alkyl quaternary ammonium chlorides are suitable reactants to prepare the intermediate hydroxy quat and are described above. The selections of the R.sup.7 and R.sup.8 substituents of the chloride quat reactant are determinative of the hydroxy quat intermediate, and therefore, of the carbonate quat product.

The metal hydroxide reactant is also as described above.

The metal chloride first step reaction product will precipitate and is easily removed, i.e. by filtration or the like, yielding a hydroxy quat/solvent reaction product. The hydroxy quat can be separated therefrom by drying or the like, if desired.

The first reaction (XVII) is conducted in a solvent as described above, and the amount of metal hydroxide reactant is as described above.

Hydroxy quat and any unreacted metal hydroxide are then reacted with at least a stoichiometric equivalent of carbon dioxide to yield the quaternary ammonium carbonate(s), and if any unreacted metal hydroxide is present, the metal carbonate(s). The conversion of the metal hydroxide to the metal carbonate is the preferred reaction of the two carbonations and will proceed more rapidly. The metal carbonate will precipitate and can be separated easily, i.e. by filtration or the like, leaving the stable carbonate quat(s) or carbonate quat(s)/solvent reaction product.

The carbonation step can also produce the bicarbonate quat or the metal carbonate quat as byproducts. The carbonate quat alone or in combination with the bicarbonate quat and/or the metal carbonate quat are suitable for use in the metal coupler-free wood preservative systems of the present invention. These carbonate quats or carbonate/bicarbonate/metal carbonate compositions, do not require a metal coupler for stabilization in a wood substrate. Completely metal-free wood preservative systems are preferred. However, if a metal carbonate quat is included in the system, preferably the metal is not a metal currently used as a coupler, and most preferably, it is an alkali metal and does not pose environmental or corrosion hazards or concerns.

Mixing, adding, and reacting of the components in the preparation of these carbonate quats can be accomplished by conventional means known to those of ordinary skill in the art. The order of addition of reactants or solvent in any individual step does not affect the process. Reactants and/or solvent can be added sequentially or simultaneously in any suitable reaction vessel. For example, the metal hydroxide may be dissolved in alcohol and the resultant mixture added to the chloride quat or the chloride quat may be dissolved in alcohol and the metal hydroxide added to the resultant mixture.

The carbon dioxide is generally bubbled for a suitable period known to those of ordinary skill in the art through the hydroxy quat/solvent supernatant after the metal chloride precipitate has been separated. Alternatively, the carbon dioxide can be added as solid dry ice directly to the hydroxy quat. Typically, this time varies from about 0.5 hour to about 1 hour at ambient temperature. Any precipitated metal carbonate is collected as is known in the art, i.e. such as by filtration.

C. Quaternary Ammonium Carboxylate

Although any quaternary ammonium carboxylates are suitable for use in the present invention, preferred carboxylate quats have the formula ##STR34## wherein R.sup.7 is a C.sub.1 -C.sub.20 alkyl or aryl-substituted alkyl group; R.sup.8 is a C.sub.8 -C.sub.20 alkyl group; but preferably R.sup.7 and R.sup.8 are the same C.sub.8 -C.sub.12 alkyl group; R.sup.9 is a substituted or unsubstituted, interrupted or uninterrupted C.sub.1 -C.sub.100 group; l and q independently are 1, 2, or 3, and (E)(q) is 1, 2, or 3; and r is 0 or an integer from 1 to 50.

Special mention is also made of carboxylate quats wherein R.sup.7 is a methyl, C.sub.8 alkyl, C.sub.9 isoalkyl, C.sub.10 alkyl, C.sub.12 alkyl, C.sub.14 alkyl or benzyl group; and R.sup.8 is a C.sub.10 alkyl, C.sub.12 alkyl, C.sub.14 alkyl or C.sub.16 alkyl group. Most preferred carboxylate quats are didecyldimethylammonium carboxylates wherein R.sup.7 and R.sup.8 are a C.sub.10 alkyl group and most preferably an n-C.sub.10 alkyl group.

Preferred carboxyl anions are derived from saturated or unsaturated mono- or poly-, including, but not limited to, di- or tri-, carboxylic acids, and particularly C.sub.1 -C.sub.20 carboxylic acids, or anhydrides thereof. R.sup.9 independently can be substituted, particularly by one or more oxygen or boron atoms or sulfate groups, or interrupted, particularly by one or more oxygen or boron atoms or sulfate groups. Special mention is made of acetic acid, gluconic acid, lauric acid, formic acid, propionic acid, butyric acid, oxalic acid, acrylic acid, tartaric acid, benzoic acid, octanoic acid, and the like. Additionally, the carboxyl group can be derived from polymeric acid. An example of a polyacid is polyacrylic acid. Examples of copolymer acids include, but are not limited to, olefin/carboxylic acid polymers such as poly(ethylene/acrylic acid).

Such acids, including the polymeric or copolymeric acids mentioned above are of the formula

((R.sup.9) (COOH).sub.(l+r)).sub.q (XIX) where R.sup.9, l, r, and q are defined as above. In polymeric copolymers carboxylic acids, R.sup.9 can be represented as ((R.sup.11).sub.s (R.sup.12).sub.t) giving ((R.sup.11).sub.s (R.sup.12).sub.t (COOH).sub.(l+r)).sub.q (XX) where R.sup.11 and R.sup.12 independently are substituted or unsubstituted, interrupted or uninterrupted as above C.sub.1 -C.sub.100 groups and s and t independently are integers from 1 to 100. Preferably, R.sup.9, R.sup.11, and R.sup.12 independently are alkyl or alkenyl groups.

Although the carboxylate quats can be prepared by a variety of methods, preferably they are prepared by an indirect synthesis, a direct synthesis, or a hydroxy quat/acid synthesis.

The indirect synthesis is illustrated below ##STR35## wherein R.sup.7 is a C.sub.1 -C.sub.20 alkyl or aryl-substituted alkyl group; R.sup.8 is a C.sub.8 -C.sub.20 alkyl group; and preferably R.sup.7 is the same as R.sup.8 and R.sup.8 is a C.sub.8 -C.sub.12 alkyl group; R.sup.10 is a straight chain C.sub.1 -C.sub.4 alkyl group; R.sup.9 is a substituted or unsubstituted, as explained above, interrupted or uninterrupted, as explained above, C.sub.1 -C.sub.100 group; l and q independently are 1, 2, or 3 and (l) (q) is 1, 2, or 3; M is a mono-, bi-, tri-valent metal, preferably a monovalent metal, and most preferably an alkali metal; r is 0 or an integer from 1 to 50; and m is 1 if M is mono-valent, 2 if M is di-valent, and 3 if M is tri-valent.

The carboxylate quat is prepared via a carbonate quat intermediate.

A C.sub.1 -C.sub.20 alkyl or aryl-substituted alkyl, C.sub.8 -C.sub.20 alkyl, and preferably a di C.sub.8 -C.sub.12 alkyl, quaternary ammonium chloride is used as a starting material and is reacted with a metal hydroxide to yield a C.sub.1 -C.sub.20 alkyl or aryl-substituted alkyl, C.sub.8 -C.sub.20 alkyl, and preferably a di C.sub.8 -C.sub.12 alkyl, quaternary ammonium hydroxide intermediate as above. The hydroxy quat intermediate(s) and any excess metal hydroxide are then reacted with carbon dioxide to yield the carbonate quat(s) and the metal carbonate(s) as above. The carbonate quat second intermediate(s) is then reacted with at least one carboxylic acid to yield the carboxylate quat(s). The selection of the C.sub.8 -C.sub.12 alkyl substituent of the chloride quat reactant is determinative of the hydroxy quat first intermediate, therefore, of the carbonate quat second intermediate, and ultimately, of the cation component of the carboxylate quat product.

The metal hydroxide reactant is described above. The preparation of the hydroxy quat is preferably conducted in a solvent as described above, and the amount of metal hydroxide reactant is described above.

Hydroxy quat and any unreacted metal hydroxide are then reacted with carbon dioxide to yield the quaternary ammonium carbonate(s) as detailed above. The carbonation step can also produce the bicarbonate quat(s) or the metal carbonate quat(s) as by-products.

The carbonate quat second intermediate(s) is then reacted with at least a stoichiometric amount of carboxylic acid(s) to yield the carboxylate quat(s).

The carboxylic acid(s) in reaction (XX) is typically added over a short period of several minutes, and the reaction typically is rapid. The carboxylate quat(s) can be separated or concentrated by filtration or evaporation after a carbon dioxide evolution in this step is completed.

In the indirect synthesis, any acid having a pKa less than that of carbonic acid, i.e., less than 6.4, such as carboxylic, phosphoric, sulfonic acids, and the like, can be reacted with a carbonate quat and displace carbon dioxide.

The addition of ammonia will retard the carbonate quat and acid reaction (XX). For example, if ammonia is added to a mixture of a polyacid and a carbonate quat, the acid-carbonate quat reaction is retarded. However, when ammonia is slowly evaporated, the reaction liberating carbon dioxide may proceed, yielding a compound that is fixed (insoluble) in wood. Similarly, a system of polyacid and acetic acid should yield an insoluble polyacid quat when the acetic acid evaporates.

Alternatively, the carboxylate quats can be prepared by a direct synthesis method. A metal salt of a carboxylic acid is reacted with a C.sub.1 -C.sub.20 alkyl or aryl-substituted alkyl, C.sub.8 -C.sub.20 alkyl, and preferably a di-C.sub.8 -C.sub.12 alkyl, quaternary ammonium chloride, in a double replacement reaction, to yield the carboxylate quat and the metal chloride salt ##STR36## wherein R.sup.7, R.sup.8, R.sup.9, M, l, q, and r are as defined above.

The metal carboxylates are derived from carboxylic acids. The carboxylic acids are as described and detailed above. The metals are mono-, di-, or the tri-valent metals, preferably mono-valent metals and most preferably alkali metals. Special mention is made of potassium and sodium.

Reaction (XXI) can be conducted neat or in a number of solvents including, but not limited to ethanol, acetic acid, or propionic acid. Preferably, the solvent comprises a C.sub.1 -C.sub.4 normal alcohol as described above. Yield will depend on the solvent and the reaction conditions selected, which can be determined by one of ordinary skill in the art through routine experimentation in accordance with this detailed explanation.

The chloride quat starting material is selected as above, and again, its selection is determinative of the cation of the carboxylate quat to be formed.

Finally, a third method for the production of the carboxylate quat(s) includes reacting hydroxy quat(s) with carboxylic acid(s). ##STR37## wherein R.sup.7, R.sup.8, R.sup.9, l, 1, and r are as defined above.

The hydroxy quat(s), carboxylic acid(s), and carboxylate quat(s) are as described above.

Mixing, adding, and reacting of the components in any of the direct, indirect or hydroxy quat/acid methods can be accomplished by conventional means known to those of ordinary skill in the art. The order of addition of reactants or solvent in any individual step does not affect the process.

D. Quaternary Ammonium Borate

Although any quaternary ammonium borates are suitable for use in the present invention, preferred borate quats have the formula ##STR38## wherein R.sup.7 is a C.sub.1 -C.sub.20 alkyl or aryl-substituted alkyl group; R.sup.8 is a C.sub.8 -C.sub.20 alkyl group; but preferably R.sup.7 and R.sup.8 are the same C.sub.8 -C.sub.12 alkyl group; a is 2 or 3, but when a is 2, b is 0 or 1 and when a is 3, b is 0, 1, or 2.

Special mention is also made of borate quats wherein R.sup.7 is a methyl, C.sub.8 alkyl, C.sub.9 isoalkyl, C.sub.10 alkyl, C.sub.12 alkyl, C.sub.14 alkyl or benzyl group; and R.sup.8 is a C.sub.10 alkyl, C.sub.12 alkyl, C.sub.14 alkyl or C.sub.16 alkyl group. Most preferred borate quats are didecyldimethylammonium borates wherein R.sup.7 and R.sup.8 are a C.sub.10 alkyl group and most preferably an n-C.sub.10 alkyl group.

Typically, the production of the borate quat(s) includes reacting hydroxy quat(s) with boric acid. ##STR39## wherein R.sup.7, R.sup.8, R.sup.9, a, and b are as defined above.

Mixing, adding, and reacting of the components in the hydroxy quat/acid method can be accomplished by conventional means known to those of ordinary skill in the art. The order of addition of reactants does not affect the process.

III. Solvents

The waterproofer and waterproofer, preservative systems of the present invention include a suitable solvent including aqueous and non-aqueous solvents. Preferably, the solvent is an aqueous solvent including, but not limited to, water, aqueous alcohol, ammonia water, aqueous acetic acid, and the like, or a combination of any of the foregoing. Organic solvents may also be used. These include, but are not limited to, mineral spirits-based solvents and the like.

IV. Waterproofer Systems and Treatment of Substrates

The amount of waterproofer used in the waterproofer systems of the present invention is a waterproofing enhancing amount, i.e. that amount effective to impart or to increase the water resistance of a substrate treated therewith.

Typically, a waterproofer system will comprise from about 0.1 to about 20 parts by weight of waterproofer and from about 80 to about 99.9 parts by weight of solvent based upon 100 parts by weight of waterproofer and solvent combined.

The components of the waterproofer systems of the present invention are mixed by conventional means known to those skilled in the art. Other conventional additives may be added as required for application to different substrates and for different uses as known to those of ordinary skill in the art. Wood substrates, such as lumber, timber, or the like, can be treated with these systems. Treatment of the substrate is accomplished by any means known to those of ordinary skill in the art including, but not limited to, dipping, soaking, brushing, pressure treating, or the like. The length of treatment time required will vary according to treatment conditions, the selection of which are known to those skilled in the art.

IV. Waterproofer, Wood Preservative Systems and Treatment of Substrates

The amount of waterproofer used in the waterproofer, wood preservative systems of the present invention is a waterproofing and compatabilizing enhancing amount, i.e. that amount effective to impart or to increase the water resistance, leaching resistance, and/or dimensional stability of the waterproofer, wood preservative system and/or the quat and to enhance the compatibility of the quats of the present invention with a solvent.

The amount of quaternary ammonium composition(s) is a biocidal effective amount, i.e. that amount effective to inhibit the growth of or to kill one or more organism that causes wood rot, to inhibit sap stain, or a combination thereof. Such organisms include, but are not limited to, Trametes viride or Trametes versicolor, which cause a white rot; Goeophyllium trabeum, which causes a brown rot; and Aspergillus niger, which causes sap stain/mold.

Typically, a waterproofer, wood preservative system will comprise from about 0.1 to about 15 parts by weight of waterproofer(s), from about 0.1 to about 10 parts by weight of quat(s), and from about 99.8 to about 75 parts by weight of solvent based upon 100 parts by weight of quat, waterproofer, and solvent combined.

The components of the waterproofer, wood preservative systems of the present invention are mixed by conventional means known to those skilled in the art preferably to form an emulsion. Preferably, the waterproofer and the quat are melted together. The melt can then be stirred, and warm water (about 40.degree. to 50.degree. C.) added with stirring to yield an emulsion or solution. Emulsions prepared in this manner may be stable for periods of at least one year.

Although other conventional additives including, but not limited to, emulsifiers may be added as required for application to different substrates and for different uses as known to those of ordinary skill in the art, metal stabilizers are not required and, in fact, are not recommended to inhibit leaching of the quat from the substrate. Accordingly, wood substrates, such as lumber, timber, or the like, can be treated with these systems.

Treatment of the substrate is accomplished by any means known to those of ordinary skill in the art including, but not limited to, dipping, soaking, brushing, pressure treating, or the like. The length of treatment required will vary according to treatment conditions, the selection of which are known to those skilled in the art.

The waterproofer, wood preservative systems of the present invention display greater resistance to leaching and greater waterproofing properties, as indicated by swell index, than wood preservatives currently used in the industry. Resistance to leaching is defined as retention of a biocidal effective amount, and preferably at least about 2% by weight, of quat in the substrate over a prolonged period of at least about 100 hours and preferably about 350 hours. Although any positive swell index indicates some waterproofing ability, a swell index of greater than about 50 indicates noteable waterproofing properties.

The cold product, after filtration, is placed in a closed flask equipped with a condenser, addition funnel, and a tube connected to a water displacement type gas measuring device. An equivalent (0.4 mole), of acetic acid is added to the carbonate quat over five minutes. Immediate gas evolution is noted, and 5.75 liters of gas are collected over 15 minutes. The solvent is removed on a rotary evaporator after the carbon dioxide evolution ceased, and yields a yellow/orange liquid.

Quat analysis reveals that the product contains 85% active quat with 0.09% free chloride and 99% exchange.
