Abstract: PROBLEM TO BE SOLVED: To obtain a cobalt catalyst for hydrogenating an org. nitrile and/or imine, wherein the catalyst has high stability to base thus attaining a long life in a basic medium. SOLUTION: A catalytically active compsn. comprises 55-98 wt.% of cobalt, 0.2-1.5 wt.% of phosphorus, 0.2-15 wt.% of manganese and 0.05-5 wt.% of an alkali metal, calculated as oxide. After the catalyst compsn. is calcined, it is reduced at a final temp. of 200-400 deg.C in a stream of hydrogen and subsequently surface-oxidized by treatment in a stream of air at a final temp. of 20-60 deg.C.
