Azomethine compounds are produced by reacting condensation products, obtained in known manner from saturated aliphatic, cycloaliphatic, aromatic and heterocyclic aldehydes and ammonia, with hydrogen in the presence of catalysts, containing at least one metal of group VIII B of the periodic table of elements, at a temperature of 20* to 200* C. and at atmospheric pressure. Preferably, the catalysts also contain at least one metal of group VI B of the periodic table of elements. |
