Composition comprising polymeric phosphite

Description

FIELD OF THE INVENTION

This invention relates to a process for the preparation of aldehydes by hydroformylation of unsaturated organic compounds in the presence of a Group VIII metal and selected polymeric phosphite ligands. The invention also relates to composition of selected hydroformylation catalysts derived from polymeric phosphite ligands and Group VIII metal.

BACKGROUND OF THE INVENTION

Phosphorus-based ligands are ubiquitous in catalysis and are used for a number of commerically important chemical transformations. Phosphorus-based ligands commonly encountered in catalysis include phosphines and phosphites. These ligands include monophosphine and monophosphite ligands, which are compounds that contain a single phosphorus atom that serves as a donor to a transition metal, and bisphosphine, bisphosphite, and bis(phosphorus) ligands, which contain two phosphorus donor atoms and normally form cyclic chelate structures with transition metals.

An industrially important catalytic reaction using phosphorus-based ligands of particular importance is olefin hydroformylation. Phosphite ligands are particularly good ligands for these reactions. For example, U.S. Pat. No. 5,235,113 describes a hydroformylation process in which an organic bidentate ligand containing two phosphorus atoms linked with an organic dihydroxyl bridging group is used in a homogeneous hydroformylation catalyst system also comprising rhodium. See also Cuny et al.,

Hydroformylation processes involving organic bidentate ligands containing two trivalent phosphorus atoms, in which the two phosphorous atoms are linked with a 2,2′-dihydroxyl-1,1′-binaphthalene bridging group, are described in U.S. Pat. No. 5,874,641 and the prior art referenced therein. U.S. Pat. No. 5,874,641 describes ligands containing substituents such as esters or ketones on the 3,3′-positions of the 2,2′-dihydroxyl-1,1′-binaphthalene bridging group. Such ligands provide reasonably good selectivity in the hydroformylation of internal olefins to terminal aldehydes.

Recovery of the ligand and catalyst is important for a successful process. Typical separation procedures to remove the product(s) from the catalyst and ligand involve extraction with an immiscible solvent or distillation. It is usually difficult to recover the catalyst and ligand quantitatively. For instance, distillation of a volatile product from a non-volatile catalyst results in thermal degradation of the catalyst. Similarly, extraction results in some loss of catalyst into the product phase. For extraction, one would like to be able to tune the solubility of the ligand and catalyst to disfavor solubility in the product phase. These ligands and metals are often very expensive and thus it is important to keep such losses to a minimum for a commercially viable process.

One method to solve the problem of catalyst and product separation is to attach the catalyst to an insoluble support. Examples of this approach have been previously described, and general references on this subject can be found in “Supported Metal Complexes”, D. Reidel Publishing, 1985, Acta Polymer., 1996, 47, 1; Comprehensive Organometallic Chemistry, Pergamon Press, 1982,553;

J. of Mol. Catal. A,

104, 1995, 17-85 and

Macromol. Symp.

80, 1994, 241. Specifically, monophosphine and monophosphite ligands attached to solid supports are described in these references. Bisphosphine ligands have also been attached to solid supports and used for catalysis, as described in for example U.S. Pat. No. 5,432,289;

J. Mol. Catal. A,

112, 1996, 217; and

J. Chem. Soc., Chem. Commun.,

1996, 653. The solid support in these prior art examples can be organic, e.g., a polymer resin, or inorganic in nature.

Polymer-supported multidentate phosphorus ligands may be prepared by a variety of methods known in the art. See U.S. Pat. Nos. 4,769,498 and 4,668,651 and published international applications WO9303839 and WO9906146 and EP 0864577 A2 and EP0877029 A2. These prior art disclose side-chain polymers containing multidentate phosphorus ligands as pendant groups.

The present invention involves another approach to improving recovery of the catalyst by providing polymeric forms of the bidentate ligands themselves.

There is an increasing need to develop a catalytic process in which the loss of catalyst composition can be substantially reduced during separation of product from the catalyst. An object of the invention is to provide a hydroformylation process. An advantage of the invention is that varying the molecular weight and degree of branching can control the solubility of the catalyst composition. Another advantage of the invention is that the catalyst composition can be substantially recovered by, for example, filtration. Other objects and advantages of the present invention will become apparent as the invention is more fully disclosed below.

in which the other positions on the aromatic ring, i.e., para or meta to the oxygen atom, can also be substituted with alkyl, ether or ester groups, or combinations of two or more thereof.

Polymer A can be produced by any means known to one skilled in the art. A process that can be used for producing polymer A disclosed above comprises (1) contacting a carbonyl compound and a monomer under a condition sufficient to produce an intermediate and (2) contacting the intermediate with phosphorochloridite under a condition effective to produce the composition disclosed in the first embodiment of the invention.

The definition and scope of the carbonyl compound, monomer, and phosphochloridite are the same as those disclosed above and, for the interest of brevity, the description of which is omitted herein.

In the first step of the process, a carbonyl compound disclosed above is contacted with a monomer disclosed above to produce an intermediate that can be a polyester or a polyamide. The contacting can be carried out with any molar ratio of the monomer to carbonyl compound so long as the ratio is sufficient to produce the intermediate. The ratio generally can be in the range of from about 0.1:1 to about 10:1, preferably about 0.5:1 to about 5:1, and most preferably about 1:1 to about 2:1. Generally the process can be carried out with either an excess of monomer or equimolar amount of monomer to carbonyl compound. The ratio of reactive ester or acid to reactive alcohol or amine of one is most preferred.

The contacting can be carried out under any condition as long as the condition is sufficient to effect the production of the intermediate. Generally it includes a temperature in the range of from about 100° C. to about 450° C., preferably about 150° C. to about 350° C., and most preferably 180° C. to 270° C., under any pressure that can accommodate the temperature range, and for a sufficient time of about 1 minute to about 24 hours. The contacting can also be carried out neat or with an inert solvent such as tetraglyme.

The resulting intermediate can be then contacted with a phosphochloridite disclosed above to form the polymeric phosphite ligand. The contacting can be carried out, if desired, in a solvent such as toluene or tetrhydrofuran under a condition sufficient to effect the production of the composition. The contacting can be carried out in the presence of a base such as an organic base. The addition of base results in the formation of a salt formed by neutralizing HCl. Suitable bases can be organic amines. Especially preferred are trialkylamines. The most preferred bases are selected from the group consisting of tributylamine, benzyldimethylamine, triethylamine, and diisopropylmethylamine. The contacting condition can include a temperature in the range of from about −50° C. to about 150° C., preferably about −40° C. to about 100° C., and most preferably, −30° C. to 80° C., under any pressure that can accommodate the temperature range, and for a sufficient time of about 1 minute to about 24 hours.

The molar ratio of the phosphochloridite to the alcohol group of the intermediate, can range from about 10:1 to about 0.5: 1, preferably about 1:1.

The phosphorochloridite can be prepared by contacting at a temperature between about −40° C. and 10° C. about one molar equivalent of PCl

3

with about two molar equivalents of substituted phenol in the absence of a base such as an organic base. The resulting solution can be then contacted with at least two equivalents of a base such as an organic base to produce a phosphorochloridite. When the substituted phenols are replaced with substituted biphenol or substituted alkylidenebisphenol, the phosphorochloridite can be similarly prepared from initially contacting about one molar equivalent of PCl

3

with about one molar equivalent of substituted biphenol or substituted alkylidenebisphenol between about −40° C. and 10° C. in the absence of an organic base. The resulting solution is then contacted with at least two equivalents of a base such as an organic base to produce a phosphorochloridite.

When preparing the phosphorochloridite in the above manner, it is desirable to maintain temperature in the −40° C. and 10° C. range during the base addition. The addition of base results in the formation of an insoluble salt formed by neutralizing HCl, the reaction mixture can become a thick slurry. Such a slurry can create problems in achieving good mixing of base, which can be important in avoiding temperature gradients in the reaction mixture that can decrease yield of the desired product. It is desirable, therefore, that the reaction be conducted with vigorous stirring or other agitation to allow effective removal of heat from the reaction mixture. Cooling to the disclosed temperature range can be accomplished by well-known techniques in the art.

The phosphochloridite can be prepared by a variety of other methods known to in the art, for example. One method involves treating phenols with PCl

3

, such as described in

Polymer,

1992, 33, 161;

When the phosphorochloridite cannot be prepared in good yield from PCl

3

, the preferred method involves the treatment of N,N-dialkyl diarylphosphoramidite derivatives with HCl. When the phosphorochloridite cannot be prepared in good yield from PCl

1963, 28, 1063; and 3,3′-dimethyl-2,2′-dihydroxydiphenylmethane which can be prepared using the procedure described in Synthesis, 1981, 2, 143.

These aromatic diols can be incorporated in a polymer as in the polyester and polyamide described above for polymer A. These polymers containing the aromatic diols can be used in polymer B of the invention.

The solubilities of these polymeric phosphite ligands above generally depend on the molecular weight of the polymer and degree of branching. For soluble polymeric system, separation can therefore be done by extraction. With insoluble polymeric systems, the catalyst can be placed in fixed beds or separated by filtration from a reaction mixture. Alternatively, the solubility of the polymer can be adjusted to be soluble in the reactants and insoluble in the products. Thus, the reaction can be carried out homogeneously to obtain high conversion. The polymeric catalyst can then be separated by easy means such as decantation or filtration.

Polymer B can also form a catalyst composition B when combined with a catalytically active metal such as Group VIII metal. The metal can be the same as that above and the description of which is omitted herein for the interest of brevity.

It is presently preferred that polymer B is produced by a process which comprises (1) contacting phosphorus trichloride and a second polyhydric alcohol under a condition sufficient to produce a phosphorus-containing polymer and (2) contacting the phosphorus-containing polymer with an aromatic diol.

The definition and scope of the second polyhydric alcohol and aromatic diol are the same as those disclosed above.

In the first step of the process, a phosphorus-containing polymer with P—Cl bonds is prepared. The polymer containing phosphorochloridite can be prepared by treating one molar equivalent of PCl

3

with about two molar equivalent of reactive hydroxy groups in the second polyhydric alcohol in the absence of an organic base. The resulting solution is then treated with at least two equivalents of a base such as, for example, an organic base to produce a polymer containing phosphorochloridite. Suitable bases are organic amines disclosed above. The condition can include a temperature in the range of from about −40° C. to about 25° C., preferably about −20° C. to about 10° C., under a pressure that can accommodate the temperature, and for a sufficient period of time which can be about 1 minute to about 24 hours. The PCl

can be blended with Cl

3

)

2

wherein Ar

3

is a C

to C

24

aryl group in which the aryl group can be substituted with alkyl, aryl, ether and ester.

The molar ratio of phosphorus trichloride to the alcohol can be any ratio so long as the ratio is sufficient to effect the production of a desired phosphorus-containing polymer. With or without blending with Cl

2

P(OAr

3

) and ClP(OAr

3

)

2

, generally the molar ratio of PCl

3

to reactive —OH groups can range from about 10:1 to about 1:3; preferably 1:2.

According to the invention, the phosphorus-containing polymer can be alternatively produced by contacting an N,N-dialkyl dichlorophosphoramidite with the second polyhydric alcohol to produce a polymeric phosphoramidite followed by contacting the polymeric phosphoramidite with an acid such as, for example, hydrochloric acid to produce the phosphorus-cotaining polymer such as, for example,polymeric phosphorochloridite. Generally any N,N-dialkyl dichlorophosphoramidite known to one skilled in the art can be used. Each of the alkyl group can contain 1 to about 20, preferably 1 to about 10 carbon atoms.

The molecular weight of the phosphorus-containing polymer can be modified by further contact with an aromatic diol that will react with unreacted P—Cl bonds. The contacting of the phosphorus-containing polymer with the aromatic diol can be carried out under a condition sufficient to produce a polymer containing a phosphite group. The contacting of the polymer containing phosphorochloridite with an aromatic diol can be carried out in the presence of a base disclosed above. Sufficient base can be used in steps (1) and (2) such that all generated HCl can be neutralized. The condition can include a temperature in the range of from about −50° C. to about 150° C., preferably about −40° C. to about 100° C., and most preferably, −30° C. to 80° C. under a pressure that can accommodate the temperature, and for a sufficient period of time which can be about 1 minute to about 24 hours.

The molar ratio of aromatic diol to unreacted P—Cl can be any ratio so long as the ratio is sufficient to effect the production of a desired phosphorus-containing polymer. The ratio generally can be in the range of from about 2:1 to about 1:2. It is most preferred that about equal mole of OH groups in the aromatic diol and the P—Cl bonds in the phosphorus-containing polymer be used.

The catalyst compositions A and B are useful for the hydroformylation of unsaturated organic compounds in which an aldehyde compound can be prepared.

The term “fluid” refers to liquid, gas, or combinations thereof. A fluid comprising hydrogen can contain about 1 to about 100% hydrogen. Similarly, a fluid comprising carbon monoxide can contain about 1 to about 100% CO. It is presently preferred that a 1:1 ratio of CO and hydrogen is used.

The reactant of the present process is an unsaturated organic compound preferably 2 to about 20 carbon atoms. Examples of suitable unsaturated organic compounds include, but are not limited to, linear terminal olefinic hydrocarbons, for example, ethylene, propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, 1-nonene, 1-decene, 1-tetradecene, 1-hexadecene, 1-octadecene, 1-eicosene and 1-dodecene; branched terminal olefinic hydrocarbons, for example, isobutene and 2- methyl-1-butene; linear internal olefinic hydrocarbons, for example, cis- and trans-2-butene, cis- and trans-2-hexene, cis- and trans-2-octene, cis- and trans-3-octene; branched internal olefinic hydrocarbons, for example, 2,3-dimethyl-2-butene, 2-methyl-2-butene and 2-methyl-2-pentene; terminal olefinic hydrocarbons; internal olefinic hydrocarbon mixtures; for example, octenes, prepared by dimerization of butenes; cyclic olefins, for example, cyclohexene, cyclooctene; and combinatins of two or more thereof.

Examples of suitable olefinic compounds also include those substituted with an unsaturated hydrocarbon group, including olefinic compounds containing an aromatic substituent such as styrene, alpha-methylstyrene and allylbenzene.

The unsaturated organic compound can also be substituted with one or more functional groups containing a heteroatom, such as oxygen, sulfur, nitrogen or phosphorus. Examples of these heteroatom-substituted ethylenically unsaturated organic compounds include vinyl methyl ether, methyl oleate, oleyl alcohol, 3-pentenenitrile, 4-pentenenitrile, 3-pentenoic acid, 4-pentenoic acid, methyl 3-pentenoate, 7-octen- 1-al, acrylonitrile, acrylic acid esters, methyl acrylate, methacrylic acid esters, methyl methacrylate, acrolein, allyl alcohol, 3-pentenal, 4-pentenal, and combinations of two or more thereof.

The process of the invention can be illustrated as follow.

Particularly preferred unsaturated organic compounds are 3-pentenenitrile, 3-pentenoic acid, 3-pentenal, allyl alcohol, and alkyl 3-pentenoate, such as methyl 3-pentenoate, and combinations of two or more thereof. The linear aldehyde compound prepared by the present process starting with one of these compounds can be used advantageously in the preparation of ε-caprolactam, hexamethylenediamine, 6-aminocaproic acid, 6-aminocapronitrile or adipic acid, which are precursors for Nylon-6 and/or Nylon-6,6.

The process of the invention also can be carried out with a mixture that comprises two or more unsaturated organic compounds. For example, 3-pentenenitrile can be present in a mixture containing 4-pentenenitrile. Because the 4- isomer reacts in a similar fashion as the corresponding 3-isomer to the desired linear aldehyde, a mixture of isomers can be used directly in the present process.

The 3-pentenenitrile may be present in mixtures containing impurities that do not interfere with the hydroformylation reaction. An example is 2-pentenenitrile.

The hydroformylation process according to the invention can be performed as described below.

The process of the invention can be carried out by any means known to one skilled in the art such as, for example, the one disclosed in U.S. Pat. No. 4,769,498, disclosure of which is incorporated herein by reference. Generally, the process can be carried out under any condition sufficient to effect the production of a desired aldehyde. For example, the temperature can be from about 0° C. to 200° C., preferably from about 50 to 150° C., and more preferably from 85° to 110° C. The pressure may vary from normal pressure to 5 MPa, preferably from 0.1 to 2 MPa. The pressure is, as a rule, can also be equal to the combined hydrogen and carbon monoxide partial pressures. However, extra inert gases may also be present; the pressure may vary from normal pressure to 15 MPa when inert gases are present. The molar ratio of hydrogen to carbon monoxide is generally between 10:1 and 1:10, and preferably between 6:1 and 1:2.

The amount of transition metal compound is selected so that favorable results can be obtained with respect to catalyst activity and process economy. In general, the concentration of transition metal in the reaction medium, which comprises an unsaturated organic compound, a catalyst composition, and solvent (if present), can be between 10 and 10,000 ppm and more preferably between 50 and 1000 ppm, calculated as free metal.

The molar ratio of the ligand to Group VIII metal is selected so that favorable results can be obtained with respect to catalyst activity and desired aldehdye selectivity. This ratio generally is from about 1 to 100 and preferably from 1 to 20 (moles phosphorus per mole metal).

The solvent may be the mixture of reactants of the hydroformylation reaction itself, such as the starting unsaturated compound, the aldehyde product and/or by-products. Other suitable solvents include saturated hydrocarbons (for example, kerosene, mineral oil, or cyclohexane), ethers (for example, diphenyl ether or tetrahydrofuran), ketones (for example, acetone, cyclohexanone), nitriles (for example, acetonitrile, adiponitrile or benzonitrile), aromatics (for example, toluene, benzene, or xylene), esters (for example, methyl valerate, caprolactone), Texanol® (Union Carbide), dimethylformamide, or combinationis of two or more thereof.

The hydroformylation process can be run in solution or in the gas phase. When the hydroformylation is carried out in the vapor (gas) phase, the preferred temperature range is from about 50° C. to about 180° C., most preferably from about 90° C. to 110° C. The temperature must be chosen so as to maintain all of the reactants and products in the vapor phase, but low enough to prevent deterioration of the catalyst. The particular preferred temperature depends to some extent on the catalyst being used, the olefinic compound being used, and the desired reaction rate. The operating pressure is not particularly critical and can conveniently by from about 0.101 to 1.01 MPa. The pressure and temperature combination must be chosen so as to maintain reactants and products in the vapor phase. A given catalyst is loaded into a reactor, such as a tubular reactor, taking care to avoid exposure of air-sensitive catalysts to O

2

from the air. A gaseous mixture of the desired olefinic compound, CO and H

2

, along with any desired diluent, such as N

2

, He or Ar, is then passed through the reactor while contacting the catalyst. The reaction products are generally liquid at room temperature and are conveniently recovered by cooling. The reactor effluent can be directly connected to a sampling valve and can be analyzed by gas chromatography. Aldehydic products, such as linear and branched butyraldehydes obtained from hydroformylation of propylene, can be quantitatively separated and analyzed using a 30 M DB-Wax® capillary GC column.

EXAMPLES

The following non-limiting, representative examples illustrate the process and catalyst compositions of this invention. All percentages are on a mole basis, unless otherwise noted. For all the examples described below, the unit formula weight of the polymers were determined based on the expected formula.

Preparation of Polyester Derived Polymeric Phosphite Containing o-cresol as Terminal Groups

Preparation of Polyester

A catalyst solution was prepared by warming 0.1 g Fascat 4102 (butyltin tris(2-ethylhexanoate)) and 10 g of 1,6-hexanediol on the hot plate in a small vial with a small magnet. The solution was kept warm. A mixture containing 5 g of dimethyl 2,2′-dihydroxy-1,1′-binaphthalene-3,3′-dicarboxylate (0.0123 mmoles; reference for preparation; see

J. Am. Chem. Soc.,

1954, 76,296 and

Tetrahedron Lett.,

1990, 413), 2.6 g of 1,6-hexanediol and 1.75 g of warm catalyst solution was placed in a 25 ml microware 1-neck rb (round bottom) flask connected to a distillation head and receiver with a precalibrated heating mantle while stirring magnetically until methanol started to distill off (the temperature was about 180° C. at which temperature the dimethyl 2,2′-dihydroxy-1,1′-binaphthalene-3,3′-dicarboxylate had all dissolved). The temperature was then increased until the 1,6-hexanediol started to reflux in the top of the flask (220° C.). The mixture was allowed to reflux for about an hour and then house vacuum was gradually applied. Full pump vacuum was then applied to distill off the excess 1,6-hexanediol. The pressure was lowered very slowly to 4 mm Hg over the next two hours in order to avoid bumping. The reaction mixture was then polymerized at 270° C. for 2 hours while distilling off most of the 1,6-hexanediol. After cooling, the reaction mixture was refluxed with 25 ml of acetone for three hours and then cooled and filtered.
