| titleOfInvention | Hydrogenation process |
| abstract | 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 certain aluminum compounds 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 DEG C. to about 175 DEG 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 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 aluminum compounds in proportions such that the Al:Pd atomic ratio is within the range from about 0.3:1 to about 0.9:1. Catalysts prepared in an ether solvent or diluent are more active than catalysts prepared in hydrocarbon solvents or diluents. |
