Abstract

A process for preparing aliphatic alpha,omega-amino nitrites by partial hydrogenation of aliphatic alpha,omega-dinitriles in the presence of a catalyst, wherein the catalyst used for the partial hydrogenation comprises (a) iron or a compound based on iron or mixtures thereof and (b) from 0.01 to 5% by weight, based on (a), of a promoter based on 2,3,4 or 5 elements selected from the group consisting of aluminum, silicon, zirconium, titanium and vanadium and (c) from 0 to 5% by weight, based on (a), of a compound based on an alkali metal or alkaline earth metal.
