Abstract

The invention relates to a process for preparing primary amines by hydrogenating nitrites in the presence of a catalyst comprising cobalt and optionally, in addition, nickel and also at least one further doping metal on a particulate support material, the cobalt and, if present, the nickel having an average particle size of from 3 to 30 nm in the active catalyst. The invention further relates to the use of the catalyst in a process for preparing primary amines by hydrogenating nitrites.
