BRIEF SUMMARY OF THE INVENTION
Technical Field
This invention relates to vicinal di(hetero)alkylene organometalate compounds comprising one or more metal oxides in association with an alkanolamine, an alkyleneamine, an alkylene glycol or mixtures thereof.
This invention also relates to an alkyleneamines producers composition rich in higher polyalkylene polyamines such as triethylenetetramine (TETA), tetraethylenepentamine (TEPA) and pentaethylenehexamine (PEHA), and to processes for the preparation thereof using the vicinal di(hetero)alkylene organometalates.
Background of the Invention
There is a substantial body of literature directed to the use of various acid catalysts to effect intramolecular and intermolecular condensation of amino compounds. U.S. Pat. No. 2,073,671 and U.S. Pat. No. 2,467,205 constitute early prior work on the use of acid condensation catalysts to condense amino compounds. U.S. Pat. No. 2,073,671 discusses, in a general fashion, the catalytic intermolecular condensation of alcohols and amines or ammonia using the same phosphate catalysts later favored by U.S. Pat. No. 2,467,205 for the intramolecular condensation of amines. The two patents are not in harmony over the use of other materials as catalysts. To illustrate this point, U.S. Pat. No. 2,073,671 states:
"Alumina, thoria, blue oxide of tungsten, titania, chromic oxide, blue oxide of molybdenum and zirconia have been mentioned in the literature for use as catalysts in carrying out these reactions but their effectiveness is so low that no practical application has been made of their use."
whereas U.S. Pat. No. 2,467,205 in describing the self-condensation of ethylenediamine (EDA) under vapor phase conditions, to initially produce ethyleneamines, but after recycle, eventually generates piperazine through multistep condensation reactions, followed by deamination, recommends "dehydration catalysts" which are thereafter characterized as
"silica gel, titania gel, alumina, thoria boron phosphate, aluminum phosphate, and the like."
U.S. Pat. No 2,073,671 describes the condensation catalyst in the following terms:
". . . a heated catalyst or contact mass containing phosphorus and especially one or more of the oxygen acids of phosphorus, their anhydrides, their polymers, and their salts; for example, orthophosphoric acid, metaphosphoric acid, pyrophosphoric acid, phosphorous pentoxide, dimetaphosphoric acid, trimetaphosphoric acid, primary ammonium phosphate, secondary ammonium phosphate, normal ammonium phosphate, ammonium metaphosphate, secondary ammonium pyrophosphate, normal ammonium pyrophosphate, aluminum phosphate, aluminum acid phosphate and mixtures of two or more of such materials."
whereas U.S. Pat. No. 2,467,205 describes one of the preferred catalysts as "basic aluminum phosphate".
U.S. Pat. No. 2,454,404 describes the "catalytic deamination of alkylene polyamines" by reacting diethylenetriamine (DETA) vapor over solid catalysts such as activated alumina, bauxite, certain aluminum silicates such as kaolin and oxides of thorium, titanium and zirconium.
U.S. Pat. Nos. 2,073,671 and 2,467,205 demonstrate a common experience in using aluminum phosphate as a condensation catalyst to produce aliphatic amines, and U.S. Pat. Nos. 2,454,404 and 2,467,205 contemplate the other solid catalysts for deamination of amines to make heterocyclic noncyclic amines. In general, the reaction conditions under which deamination to effect cyclization occurs are more severe than those employed for condensation to generate noncyclic molecules, all other factors being comparable.
U.S. Pat. Nos. 4,540,822, 4,584,406 and 4,588,842 depict the use of Group IVB metal oxides as supports for phosphorus catalysts used to effect the condensation of amino compounds with alkanolamines.
U.S. Pat. No. 4,683,335 describes the use of tungstophosphoric acid, molybdophosphoric acid or mixtures deposited on titania as catalysts for the condensation of amines and alkanolamines to make polyalkylenepolyamines.
U.S. Pat. Nos. 4,314,083, 4,316,840, 4,362,886 and 4,394,524 disclose the use of certain metal sulfates as useful catalysts for the condensation of alkanolamine and an amino compound. No distinction is made between the sulfur compounds in respect to catalytic efficacy. Sulfuric acid is as good as any metal sulfate, and all metal sulfates are treated as equivalents. At column 8 of U.S. Pat. No. 4,314,083, it is noted that boron sulfate "gave extremely high selectivity at a low level" of EDA. However, selectivity in general was shown to increase with an increase of EDA relative to MEA in the feed. The only specific metal sulfates disclosed in the patents are antimony sulfate, beryllium sulfate, iron sulfate and aluminum sulfate.
In the typical case of the manufacture of alkyleneamines, mixtures with other alkyleneamines (including a variety of polyalkylenepolyamines and cyclic alkylenepolyamines) are formed. The same holds true when the object of the process is to produce polyalkylenepolyamines whether acyclic or cyclic, in that a variety of amino compounds are also formed. Each of these cyclic and acyclic alkyleneamines can be isolated from the mixture.
The acid catalyzed condensation reaction involving the reaction of an alkanolamine with an amino compound in the presence of an acidic catalyst is believed to proceed through the mechanism of esterifying free surface hydroxyl groups on the acid catalyst with the alkanolamine and/or by protonating the alkanolamine in the presence of the acid catalyst, followed by loss of water and amine condensation of the ester or the hydrated species, as the case may be, to form the alkyleneamine. Illustrative prior art directed primarily to the cyclic polyalkylenepolyamines (heterocyclic polyamines), but not necessarily limited to the aforementioned acid condensation reaction, are: U.S. Pat. Nos. 2,937,176, 2,977,363, 2,977,364, 2,985,658, 3,056,788, 3,231,573, 3,167,555, 3,242,183, 3,297,701, 3,172,891, 3,369,019, 3,342,820, 3,956,329, 4,017,494, 4,092,316, 4,182,864, 4,405,784 and 4,514,567; European Patent Applications 0 069 322, 0 111 928 and 0 158 319; East German Patent No. 206,896; Japanese Patent Publication No. 51 141895; and French Patent No. 1,381,243. The evolution of the art to the use of the acid catalyzed condensation reaction to generate acyclic alkyleneamines, particularly acyclic polyalkylenepolyamines, as the predominant products stemmed from the initial disclosure in U.S. Pat. No. 4,036,881, though earlier patent literature fairly well characterized such an effect without labeling it so, see U.S. Pat. No. 2,467,205, supra. The acid catalysts are phosphorus compounds and the reaction is carried out in the liquid phase. The trend in this catalyst direction was early set as demonstrated by U.S. Pat. Nos. 2,073,671 and 2,467,205, supra. A modification of this route includes the addition of ammonia to the reaction, see, for example, U.S. Pat. No. 4,394,524 and U.S. Pat. No. 4,463,193 for the purpose of converting alkanolamine such as MEA in situ to alkylene amine such as EDA by reaction with ammonia, and the EDA is in situ reacted with MEA according to the process of U.S. Pat. No. 4,036,881 to form alkyleneamines.
A summary of the prior art employing acid catalysts for making alkyleneamines is set forth in Table 1 below.

The market demand for higher polyalkylene polyamines such as TETA, TEPA and PEHA has been progressively increasing in recent years. These higher polyalkylene polyamines are desirable co-products with DETA. It would be desirable to satisfy the existing demand from a cost standpoint by modifying slightly the commercial processes directed to the manufacture of DETA from the reaction of MEA and EDA or other suitable starting raw materials such as DETA and AEEA, to the production of TETA, TEPA and PEHA as major products.
It would be desirable to have continuously produced compositions, generated by the reaction of MEA and EDA or other suitable starting raw materials such as DETA and AEEA over a fixed bed of a condensation catalyst under commercial conditions, that are rich in TETA, TEPA and PEHA, and that are not disproportionately high in PIP and other cyclics.
It would be very beneficial to have a process which increases one's ability to generate the manufacture of desirable higher polyalkylene polyamine products such as TETA, TEPA and PEHA without generating large amounts of cyclic alkylenepolyamine products. In addition, it would also be desirable to have a process with raw material flexibility which provides the potential to control congener distribution, linear to cyclic selectivity and linear to branched selectivity of the higher polyalkylene polyamines products. As used herein, congener distribution refers to polyalkylene polyamines containing the same number of nitrogen atoms but not necessarily having the same molecular weight or structure.
The above features are provided by this invention.

DETAILED DESCRIPTION
The higher polyalkylene polyamines such as TETA, TEPA and PEHA are very useful commercial products for a variety of applications including fuel oil additives, corrosion inhibitors, fabric softeners, fungicides and others. As indicated above, there is lacking a commercial process for the manufacture of enhanced quantities of TETA, TEPA and PEHA especially as significant products of reaction. There is thus a need for the ability to commercially generate larger production quantities of TETA, TEPA and PEHA and that is the direction of this invention. The process of this invention provides for the reaction of MEA and DETA or other suitable starting raw materials such as EDA and AEEA to produce in a continuous manner a reaction product mixture, termed herein an "alkyleneamines producers composition", in which TETA, TEPA and PEHA are principal products of the reaction.
The process of this invention is distinctive insofar as it achieves the generation of high concentrations of TETA, TEPA and PEHA in a manner which can be suitably employed in a commercial process, particularly a continuous process, for the manufacture of alkyleneamines. In particular, the process of this invention allows the production of TETA, TEPA and PEHA in relatively high yields without generating large amounts of cyclic polyalkylene polyamine products. The process of this invention provides starting raw material flexibility thereby allowing the potential to control congener distribution, linear to cyclic selectivity and linear to branched selectivity of the higher polyalkylene polyamine products.

It is appreciated that chelation may be provided by certain substituents of the vicinal di(hetero)alkylene organometalates. For purposes of this invention, the formulae depicted herein embrace any permissible coordinate valence forces.
The general structure of the vicinal di(hetero)alkylene organometalates of this invention may be responsible for improved selectivity to acyclic amine products due to increased steric hinderance or chelation to preclude intramolecular cyclic amines formation. The vicinal di(hetero)alkylene organo metalates should be amenable to displacement by a suitable nucleophile such as an alkyleneamine or alkanolamine in order to form the desired amine product. Suitable nucleophiles can react with the vicinal di(hetero)alkylene organometalate compounds from the bulk, i.e., not associated with a catalytic site, or with proximally bound (coordinated) vicinal di(hetero)alkylene organometalates. This nuclophile displacement will be governed by the electronic properties of M.sup.1 and M.sup.2 including bond energies and electron affinities. It has been found that these properties can be altered by the utilization of other metal oxides in the preparation of vicinal di(hetero) alkylene organometalates, for example, a major metal oxide in association with one or more minor metal oxides.
Particularly preferred major metal oxides for use in this invention include, for example, one or more oxides of titanium, zirconium, hafnium, aluminum, boron, gallium, germanium, tin, iron, vanadium, niobium, tantalum, antimony, uranium, thorium, silicon, zinc and the lanthanides. Representative metalates which readily form the vicinal di(hetero)alkylene organometalates when contacted with an alkanolamine, as alkyleneamine, an alkylene glycol or mixtures thereof include, for example, titanates, aluminates, silicates, stannates, borates and the like. The metalate anion comprises at least one di(hetero)alkylene moiety, however, more than one di(hetero)alkylene moiety is possible since it is recognized that the actual chemical formula under the reaction conditions of the process is subject to change. As indicated above, these complexes should be amenable to reaction with suitable nucleophiles.
Suitable minor metal oxides are selected on the basis of electrophilicity and coordination with the major metal oxide For example, one or more minor metal oxides are chosen which will increase the electropositive nature of the major metal oxide and thus effectuate the formation of the vicinal di(hetero)alkylene organometalates. Preferred minor metal oxides include, for example, any of the major metal oxides described above and additionally bismuth, osmium, iridium, rhenium, molybdenum, chromium and tungsten As described more fully below, the minor metal oxides may be introduced as impregnates on the major metal oxide by conventional procedures known in the art such as incipient wetness or by co precipitation or mulling of the mixed metal oxides which affords a more uniform distribution. The minor metal oxides may also form vicinal di(hetero)alkylene organometalates which alters the product mix vis-a-vis the major metal oxide.
In an embodiment of this invention, an oxyacid having a divalent or polyvalent anion or a divalent or polyvalent metal salt of an oxyacid or mixtures thereof may be introduced as impregnates to improve the metal oxide(s) performance (activity/ selectivity/stability). These polyoxyanions can alter the electronic properties of the metal oxide(s) and thus effectuate the formation of vicinal di(hetero)alkylene organometalates. While not wishing to be bound to any particular theory, it is believed that these polyoxyanions serve as bridging ligands and may not be involved with the formation of the vicinal di(hetero)alkylene organometalate per se. Suitable oxyacids having a divalent or polyvalent anion or a divalent or polyvalent metal salt of an oxyacid include, for example, sulfuric acid, phosphoric acid, tungstic acid, molybdic acid, telluric acid, selenic acid, tunstophosphoric acid, silicotungstic acid, ammonium metatungstate, sodium tetraborate and the like including mixtures thereof.

Thus, a second vicinal di(hetero)alkylene organometalate compound may or may not be formed in the process of this invention. However, the formation of a second vicinal di(hetero)alkylene organometalate compound may provide improved linear/branched product ratios for the TETA's and higher polyalkylene polyamines.

The one or more metal oxides are effective as catalysts in the process of this invention. Preferred metal oxides are amphoteric or slightly acidic or slightly basic. Although acidity is thought to play some role in the activity of these metal oxides, it is believed that the improved activity and selectivity exhibited by these metal oxides cannot be attributed solely to an increase in either Lewis or Bronsted acidity.

For mixed metal oxides in which at least one of the metals is titanium, suitable metals in association with titanium may include, for example, one or more of the following: Group IIIB metals such as scandium, yttrium and lanthanum including the lanthanides, Group VB metals such as niobium and tantalum, Group VIB metals such as chromium, molybdenum and tungsten, Group VIII metals such as iron, cobalt and nickel, Group IIB metals such as zinc and cadmium, Group IIIA metals such as boron, aluminum, gallium and indium, Group IVA metals such as silicon, germanium, tin and lead, Group VA metals such as arsenic, antimony and bismuth, and Group IVB metals such as zirconium and hafnium.

Group VIB metal containing substances may be used as performance moderators in accordance with this invention. Suitable Group VIB metal containing substances are disclosed in U.S. patent application Ser. No. 390,708, filed on an even date herewith and incorporated herein by reference. Illustrative of Group VIB metal-containing performance moderators include, for example, one or more oxides of tungsten, chromium, molybdenum or mixtures thereof.
A variety of conventional phosphorus-containing substances may be suitable for use as performance moderators in this invention. As indicated above, the conventional substances should be capable of functioning as a performance moderator. Illustrative of conventional phosphorus containing substances may include, for example, those disclosed in U.S. Pat. No. 4,036,881, U.S. Pat. No. 4,806,517, U.S. Pat. No. 4,617,418, U.S. Pat. No. 4,720,588, U.S. Pat. No. 4,394,524, U.S. Pat. No. 4,540,822, U.S. Pat. No. 4,588,842, U.S. Pat. No. 4,605,770, U.S. Pat. No. 4,683,335, U.S. Pat. No. 4,316,841, U.S. Pat. No. 4,463,193, U.S. Pat. No. 4,503,253. U.S. Pat. No. 4,560,798 and U.S. Pat. No. 4,578,517.
Suitable conventional phosphorus containing substances which may be employed as performance moderators in this invention include acidic metal phosphates, phosphoric acid compounds and their anhydrides, phosphorous acid compounds and their anhydrides, alkyl or aryl phosphate esters, alkyl or aryl phosphite esters, alkyl or aryl substituted phosphorous acids and phosphoric acids, alkali metal monosalts of phosphoric acid, the thioanalogs of the foregoing, and mixtures of any of the above.
The amount of the performance moderator of the mineral acid type used with the one or more metal oxides is not narrowly critical. Generally, the amount does not exceed 25 weight percent of the weight of the one or more metal oxides. As a rule, it is desirable to use at least 0.01 weight percent of the weight of the one or more metal oxides. Preferably, the amount of performance moderator, when used, will range from about 0.2 to about 10 weight percent of the weight of the one or more metal oxides. Most preferably, the amount of performance moderator, when used, will range from about 0.5 to about 5 weight percent of the weight of the one or more metal oxides.
The amount of performance moderator other than the mineral acid type used with the one or more metal oxides is not narrowly critical. Generally, the amount does not exceed 90 weight percent of the weight of the one or more metal oxides. The amount of performance moderator can range from about 0 to about 90 or greater weight percent of the weight of the one or more metal oxides, preferably from about 0 to about 75 weight percent of the weight of the one or more metal oxides, and more preferably from about 0 to about 50 weight percent of the weight of the one or more metal oxides. Most preferably, the amount of performance moderator, when used, will range from about 0.5 to about 25 weight percent of the weight of the one or more metal oxides.
The performance moderator can be provided to the one or more metal oxides by conventional procedures known in the art. For example, the performance moderator can be provided to the one or more metal oxides by impregnating particles or monolithic structures comprising the one or more metal oxides with liquid comprising the performance moderator. This is a well known procedure in the art for incorporating additives to a solid support material. The one or more metal oxides may be utilized as solid powders or as fused, bonded or compressed solid pellets, or larger structures in association with the one or more other metal oxides, or as coated, fused, bonded or compressed solid pellets, or larger structures, composited with one or more support materials, in association with one or more other metal oxides. These solid structures may be treated with the performance moderator by mixing a liquid body of the performance moderator with the solid structure. For example, the one or more metal oxide solids may be slurried in the performance moderator, drained, washed and suctioned to remove excess performance moderator, and then dried with heat to remove any volatiles accompanying the performance moderator. The drying temperature chosen will depend on the nature of the volatiles to be removed. Usually, the time/temperature for effecting drying will be below the conditions for effecting dehydration to remove bound water from the one or more metal oxides. Normally the drying temperature will be greater than about 120.degree. C. and below about 600.degree. C. depending on the thermal stability of the one or more metal oxides. The drying time will generally go down as the drying temperature rises and vice versus, and may extend from 5 seconds to about 24 hours.
Alternatively, the one or more metal oxides may be condensed from their respective hydrolyzable monomers to the desired oxides to form oxide powders which can thereafter be blended and compressed with the performance moderator to form pellets and larger structures. The one or more metal oxides can be provided from metal salts which can be heated to form the metal oxide. It is appreciated that the performance moderator can be incorporated into the molecular bonding configuration of the one or more meta oxides by conventional procedures known in the art.
The one or more metal oxides prior to the optional treatment of the performance moderator may be prepared in a wide variety of ways. For example, one or more metal oxides may be provided as a partial condensate on a support, such as a silica or alpha, beta or gamma alumina, silicon carbide, and the like, and then condensed by heating to effect polymerization to the desired oxide form. The metal oxide(s) may be condensed from hydrolyzable monomers to the desired oxide, indeed, to form an oxide powder which can thereafter be compressed to form pellets and larger structures of the metal oxide(s). The powder can be made into a shapeable paste which can be extruded and cut into pellets according to conventional procedures. The extrudate may thereafter be fired to cure the metal oxide(s) and fix the structure. The cut extrudate may be blended with a support material such as those characterized above, and the blend fired to fuse the metal oxide(s) to the support.
In a preferred embodiment of this invention, a high surface area silica or titania can be slurried with an aqueous solution of ammonium metatungstate, extruded, and calcined at a temperature of about 400.degree. C.
A preferred structure comprises one or more oxides of a Group VIB metal in association with a Group IVA or IVB metal oxide having a surface area of at least a 140 m.sup.2 /gm which may or may not be bonded to a support material. The term "support," as used herein and in the claims, means a solid structure which does not adversely affect the properties of the vicinal di(hetero)alkylene organometalate and is at least as stable as the one or more metal oxides to the reaction medium. The support may act in concert with the one or more metal oxides to moderate the reaction. Some supports may contribute to the selectivity of the reaction. The structure can comprise from about 2 to about 60 percent by weight or greater of the support, more preferably from about 10 to about 50 percent by weight of the support, the remainder being the weight of the metal oxide(s). Included in the weight of the support is the weight of any binding agent such as phosphates, sulfates, silicates, fluorides, and the like, and any other additive provided to stabilize or otherwise help in the manufacture of the vicinal di(hetero)alkylene organometalate. The support may be particles as large or larger than the metal oxide component and "glued" to the metal oxide by virtue of a binding medium.
The support may constitute a separate phase in the process of extruding the structure. In this embodiment, the support forming material, preferably as a paste is blended with a paste of the one or more metal oxides or a partial condensate thereof. The paste may comprise the oxide forms of the support, which is blended with water and/or binding agents. The extrudate of the blend is passed through a multiorificed die and chopped into pellets of the desired sizes. The particles may be doughnut shaped, spherical, and the like. Then the particles are calcined to dry them and complete any condensation reaction in the support and/or the metal oxide(s).
The use of supports for the one or more metal oxides provide a number of significant advantages. It has been determined that some of the metal oxides are not as stable in the amines reaction media when utilized over an extended period of time. When the reaction is effected as a batch reaction, this matter is not a problem. However, when the reaction is effected with the one or more metal oxides as part of a fixed bed in a tubular reactor, the preferred procedure for carrying out the invention, it is desirable to have the metal oxide(s) be more stable. When the metal oxide(s) is combined with the support, the metal oxide(s) has greater stability for the reaction medium, and therefore, it is better able to be used in a fixed bed of a continuous reactor. The supported metal oxide(s) suffer from none of the leaching problems that the metal oxides per se may have or the problems that are associated with the prior art substances, such as acidic phosphorus compounds on silica.
The reactants used in the condensation process of the invention may be ammonia or organic compound containing --NH--and any compound possessing an alcoholic hydroxyl group, subject to the following: the intramolecular condensation of an amino compound produces an amine having a lower molecular weight, and the intermolecular condensation of an amino compound with one or more of another amino compound or a compound containing an alcoholic hydroxyl group produces an amine having a lower, same or higher molecular weight than the reactants.
The one or more metal oxides are preferably contacted in situ with one or more alkanolamines, alkyleneamines, alkylene glycols or mixtures thereof to form the vicinal di(hetero)alkylene organometalates of this invention. As indicated above, an oxyacid having a divalent or polyvalent anion or a divalent or polyvalent metal salt of an oxyacid or mixtures thereof may be introduced as impregnates to improve the performance of the one or more metal oxides. These polyoxyanions can alter the electronic properties of the one or more metal oxides and thus effectuate the formation of vicinal di(hetero)alkylene organometalates. The vicinal di(hetero)alkylene organometalates should be amenable to displacement by a suitable nucleophile such as alkyleneamine or alkanolamine in order to form the desired amine products. Illustrative of suitable reactants in effecting the process of the invention, include by way of example:
Ammonia
MEA - monoethanolamine
EDA - ethylenediamine
MeEDA - methylethylenediamine
EtEDA - ethylethylenediamine
AEEA - N-(2-aminoethyl)ethanolamine
HEP - N-(2 hydroxyethyl)piperazine
DETA - diethylenetriamine
AEP - N-(2 aminoethyl)piperazine
TAEA - trisaminoethylamine
TETA - triethylenetetramine
TEPA - tetraethylenepentamine
PEHA - pentaethylenehexamine
TETA Isomers:
TAEA - trisaminoethylamine

iAEPEEDA - isoaminoethylpiperazinoethylethylenediamine
AEDAEP - aminoethyldiaminoethylpiperazine
BPEA - bispiperazinoethylamine
The foregoing also can represent the products of the reaction. For example, MEA and DETA are frequently employed to produce TETA along with a variety of other amines, most of which are set forth above.
Glycol compounds can also be employed in the preparation of vicinal di(hetero)alkylene organometalates of this invention. For purposes of this invention, glycol compounds embrace diols and polyols. Illustrative of suitable glycol compounds include alkylene glycols such as ethylene glycol, propylene glycol, 1,3-propane diol or mixtures thereof.
The process may be effected in the liquid or vapor or supercritical liquid states or mixtures thereof though the actual reaction is believed to occur on the metal oxide's solid surface in the absorbed state. In this context, the vapor phase reaction is intended to refer to the general vapor state of the reactants. Though the reaction conditions may range from subatmospheric to superatmospheric conditions, it is desirable to run the reaction from about 50 psig to about 3,000 psig, preferably from about 200 psig to about 2,000 psig.
The temperature of the reaction may be as low as about 125.degree. C. to about 400.degree. C. Preferably, the reaction temperature ranges from about 150.degree. C. to about 350.degree. C., and most preferably from about 225.degree. C. to about 325.degree. C.
The reaction may be effected by the incremental addition of one of the reactants to the other or by the joint addition of the reactants to the one or more metal oxides. The preferred process effects the reaction in a continuous manner over a fixed bed of one or more metal oxides in a tubular reactor. However, the reaction may be carried out by slurrying one or more metal oxides in the reactants or in a batch mode in an autoclave. An inert such as nitrogen, methane or the like can be used in the reaction process.
The preferred process involves the formation of alkyleneamines from the intermolecular condensation of alkanolamines and alkyleneamines or the intramolecular condensation of alkyleneamines or alkanolamines. Illustrative of such reactions are the following reactant combinations:

Further, while not wishing to be bound to any particular reaction mechanism, it is believed that the mechanistic pathway for making AEEA by the condensation of MEA in the presence of tungsten oxide or a suitable tungsten salt occurs as follows: ##STR16##
As used in the mechanistic pathways depicted above and the formulae herein, the --line indicates coordinate valence forces. It is recognized that the actual reaction mechanism may be different.
The process of the invention provides the ability to generate the manufacture of desirable higher polyalkylene polyamine products such as TETA, TEPA and PEHA without generating large amounts of cyclic alkylenepolyamine products such as PIP, AEP and HEP. The alkyleneamines producers composition of this invention has a TETA+TAEA to PIP+AEP+PEEDA+DAEP+DPE weight ratio of greater than about 0.5 and a TETA to TAEA weight ratio of greater than about 6.0. The process of this invention provides the potential to control congener distribution, linear to cyclic selectivity and linear to branched selectivity of the higher polyalkylene polyamines.
It is appreciated that the vicinal di(hetero)alkylene organometalates of this invention may also be useful in the production of alkylamines, for example, an alcohol and at least one of ammonia, a primary amine, a secondary amine or a tertiary amine may be contacted in the presence of one or more metal oxides to provide vicinal di(hetero)alkylene organometalates which can be utilized under conditions effective to produce alkylamines
