FIELD: hydrogenation catalyst. SUBSTANCE: above-mentioned alloy is mixed with polyvinyl alcohol and water or with stearic acid to give plastic mass. The latter is used to mold products, which are calcined and then treated with alkali metal hydroxide. Thus obtained catalyst is used in a process of production of aliphatic α,ω-aminonitriles by way of partial gas-phase or liquid-phase hydrogenation in presence of solvent, gas-phase process being carried out at temperature between 100 and 250 C and pressure 0.1 to 30 bar and liquid-phase one at 20-150 C and 20-300 bar. Solvent may be selected from starting dinitrile, ammonia, amines, diamines, and triamines having 1-5 carbon atoms, and alkanols. EFFECT: simplified technology and reduced expenses. 8 cl, 4 ex
