Abstract: A hydrogenation catalyst based on an alloy of aluminum and of a transition metal is prepared by preparing a kneaded material from the alloy and an assistant, converting the kneaded material into moldings, calcining the moldings and treating the calcined moldings with an alkali metal hydroxide, by a process in which the assistant used is (a) polyvinyl alcohol and water or (b) stearic acid, and the catalyst prepared according to the invention is used for hydrogenation and hydrogenolysis, in particular the partial hydrogenation of aliphatic alpha,omega-dinitriles to aliphatic alpha,omega-aminonitriles.

Abstract: The invention concerns the production of a hydrogenation catalyser based on an aluminium/transition metal alloy. The proposed method involves producing a kneadable material from the alloy and an auxiliary agent, moulding the kneadable material into moulded articles, calcinating these articles and then treating them with an alkali metal hydroxide, using (a) polyvinyl alcohol and water or (b) stearic acid as the auxiliary agent. The invention also concerns methods of hydrogenation and hydrogenolysis, in particular the partial hydrogenation of aliphatic alpha , omega -dinitriles to alpha , omega -aminonitriles; and the use of the catalysers thus produced for hydrogenation and hydrogenolysis.

Abstract: A process for the hydrogenation of an organic compound containing at least one carbonyl group comprises bringing the organic compound in the presence of hydrogen into contact with a shaped body which can be produced by a process in which (i) an oxidic material comprising copper oxide, zinc oxide and aluminum oxide is made available, (ii) pulverulent metallic copper or pulverulent cement or a mixture thereof is added to the oxidic material, and (iii) the mixture resulting from (ii) is shaped to form a shaped body.
