Abstract: A process is disclosed for preparing aliphatic alpha , omega -aminonitriles by partially hydrogenating aliphatic alpha , omega -dinitriles at an increased temperature and pressure in the presence of a solvent and a catalyst. The process is characterised in that the catalyst is obtained by thermally decomposing a metal compound selected in the group made up of metal carbonyl compounds, metal salts of C1-C6-carboxylic acids and C2-C6-dicarboxylic acids and metal complexes with diketones until the corresponding metal and/or a metal oxide thereof is obtained, provided that the metal used be nickel or cobalt.
