Abstract: In the present invention, there is disclosed a catalyst suitable for preparing aliphatic alpha, omega-aminonitriles by partial hydrogenation of aliphatic dinitriles containing: (a) metallic cobalt, a cobalt compound or a mixture thereof wherein the proportion of metallic cobalt based on (a) being from 20 to 100 percent by weight, (b) from 10 to 70 percent by weight, based on the component (a), of metallic iron, iron oxide, a further iron compound or a mixture thereof wherein the proportion of iron oxide based on the component (b) being from 20 to 100 percent by weight, and (c) from 0 to 1 percent by weight, based on the sum of the component (a) and (b), of a compound based on an alkali metal, an alkaline earth metal or zinc. Disclosed is also a process for preparing aliphatic alpha, omega-aminonitriles by partial hydrogenation of aliphatic dinitriles at elevated temperature and elevated pressure being carried out in the presence of the above-described catalyst, preferably at pressure ranging within 2 to 30 MPa and temperature in the range of 20 to 150 degC.
