An improved process for the catalytic hydrogenation of nitriles. The basic process comprises contacting the nitrile with hydrogen in the presence of a sponge or Raney cobalt catalyst under conditions for effecting conversion of the nitrile group to the primary amine. The improvement in the hydrogenation process resides in effecting the hydrogenation in the presence of a catalytic amount of lithium hydroxide and water. To achieve a catalytic amount of lithium hydroxide, the catalyst may be pretreated with the lithium hydroxide and/or the reaction may be carried out with the lithium hydroxide present in the reaction medium.
