Abstract

Process for the continuous preparation of an amine by reaction of a primary or secondary alcohol, aldehyde and/or ketone with hydrogen and a nitrogen compound selected from the group consisting of ammonia, primary and secondary amines at a temperature in the range from 60 to 300° C. in the presence of a copper-containing catalyst, wherein the catalytically active composition of the catalyst prior to reduction with hydrogen comprises
