Abstract

Cobalt catalysts whose catalytically active material comprises from 55 to 98 wt % of cobalt, from 0.2 to 15 wt % of phosphorus, from 0.2 to 15 wt % of manganese, and from 0.2 to 15 wt % of alkali metal, calculated as oxide, in which the catalyst material is calcined in a first step at final temperatures of from 550.degree. to 750.degree. C. and in a second step at final temperatures of from 800.degree. to 1000.degree. C., and a process for the hydrogenation of organic nitriles and/or imines, in which the novel cobalt catalyst is used.
