摘要： A hydrogenation catalyst prepared by combining a Group VIIIA metal compound and a hydrocarbyl-substituted silicon alumoxane and a hydrogenation process wherein said catalyst is used to hydrogenate compounds containing ethylenic and/or aromatic unsaturation. The Group VIIIA metal compound is selected from the group of compounds consisting of carboxylates, chelates, alkoxides, salts of hydrocarbon acids containing sulfur and salts of partial half esters of hydrocarbyl acids containing sulfur. Nickel, cobalt and palladium compounds are particularly preferred for use in the hydrogenation catalyst. Hydrogenation catalysts prepared with hydrocarbyl-substituted silicon slumoxanes initially exhibit less hydrogenation activity than catalysts known heretofore in the prior art and prepared with a metal alkyl of a metal selected from Groups, I, II and III. These catalysts, then afford greater control over the extent of hydrogenation, particularly when partial hydrogenation is a desired end result. Ultimately, however, the catalyst permits substantially complete hydrogenation of both ethylenic and aromatic unsaturation.

摘要： A hydrogenation catalyst prepared by combining one or more Group VIII metal compounds with one or more alkylalumoxanes and one or more alkyls or hydrides of a metal selected from the group consisting of the Group Ia, IIa, and IIa metals and a hyrogenation process wherein said catalyst is used to hydrogenate compounds containing ethylenic and/or aromatic unsaturation. Preferably, the one or more Group VIII metal compounds will be contacted sequentially with the one or more alkylalumoxanes and the one or more alkyls or hydrides, first with the one or more alkylalumoxanes and then with one or more alkyls and/or hydrides. The one or more Group VIII metal compounds is selected from the group of compounds consisting of carboxylates, chelates, alkoxides, salts of acids containing sulfur, salts of partial esters of acids containing sulfur and salts of aliphatic and aromatic sulfonic acids. Nickel and cobalt compounds are preferred for use in the hydrogenation catalysts. Certain of the hydrogenation catalyst, particularly those prepared with a methylalumoxanes, initially exhibit less hydrogenation activity than catalysts known heretofore in the prior art and prepared with a metal alkyl and/or hydride of a metal selected from Groups Ia, IIa and IIIa of the Periodic Table of Elements. These catalysts, then, permit greater control over the extent of hydrogenation, particularly when partial hydrogenation is a desired end result. Ultimately, however, these catalyst permits substantially complete hydrogenation of both ethylenic and aromatic unsaturation.

摘要： A hydrogenation catalyst prepared by combining a Group VIIIA metal compound and an alkylalumoxane and a hydrogenation process wherein said catalyst is used to hydrogenate compounds or materials containing ethylenic and/or aromatic unsaturation. The Group VIIIA metal compound is selected from the group of compounds consisting of carboxylates, chelates, alkoxides, salts of acids containing sulfur, salts of partial half esters of acids containing sulfur and salts of aliphatic and aromatic sulfonic acids. Nickel and cobalt compounds are preferred for use in preparing the hydrogenation catalyst. Hydrogenation catalysts prepared with methylalumoxane initially exhibit less hydrogenation activity than catalysts known heretofore in the prior art and prepared with a metal alkyl of a metal selected from Groups I, II and III. These catalysts, then, permit or enable greater control over the extent of hydrogenation, particularly when partial hydrogenation is a desired end result. Ultimately, however, the catalyst permits substantially complete hydrogenation of both ethylenic and aromatic unsaturation. Hydrogenation catalysts prepared with higher alkyl (C.sub.2 -C.sub.8) alumoxanes on the other hand are generally more active at all hydrogenation times at least those greater than about 30 minutes.

摘要： A process for selectively hydrogenating a polymer containing ethylenic unsaturation and cyano groups with a catalyst prepared by combining one or more of certain palladium compounds and one or more of alkylalumoxanes in a suitable solvent or diluent. The hydrogenation is accomplished in a suitable solvent for the polymer at a temperature within the range from about 20.degree. C. to about 175.degree. C. at a total pressure within the range from about 50 to about 1,000 psig and at a hydrogen partial pressure within the range from about 50 to about 950 psig. The hydrogenation can be accomplished so as to convert at least about 85% of the ethylenic unsaturation contained initially in the polymer without converting a significant portion (less than about 5%) of the cyano groups to amine groups. Best results are achieved when the catalyst is prepared by combining the one or more palladium compounds and the one or more alkylalumoxanes in proportions such that the Al:Pd atomic ratio is preferably within the range from about 0.2:1 to about 10:1.
