Abstract: Amines are prepared by reacting primary or secondary alcohols, aldehydes or ketones with nitrogen compounds selected from the group consisting of ammonia and primary and secondary amines at elevated temperatures and superatmospheric pressures in the presence of hydrogen and of a catalyst containing copper and oxygen-containing compounds of titanium by a process in which the catalyst is used in the form of moldings which have been prepared with the addition of metallic copper powder.
