This invention relates to a process for preparing primary amines by hydrogenation of mono and/or dinitrile with hydrogen in the presence of a nickel and/or cobalt catalyst on support and optionally in the presence of ammonia, this process being characterized in that a nickel and/or cobalt catalyst on support is used, optionally in combination with at least one solid, reaction medium-insoluble cocatalyst, the catalyst and/or the cocatalyst being substantially nonacid.

Process for preparing primary amines and catalyst system suitable

This invention relates to a process for preparing secondary alkylamine by selective hydrogenation of alkylnitrile using a nickel-containing catalyst which contains copper as promoter, said catalyst having a selectivity, as herein defined, of not more than 8.
