ABSTRACT:
A process for the preparation of tertiary aliphatic amines containing an alkyl or alkenyl radical having 8 to 24 carbon atoms and at least one methyl group by reacting a liquid alcohol or aldehyde having 8 to 24 carbon atoms in the presence of a copper-chromium oxide catalyst with a gaseous mixture containing hydrogen and a lower primary or secondary alkyl amine having at least one methyl group, the amine proportion of the gas mixture being in the range of from 1 to 20% by volume, eliminating the water having been formed in the reaction from the gaseous mixture, and recirculating the gaseous mixture continuously back into the liquid alcohol or aldehyde.
