Abstract
A process for the production of predominantly primary and secondary amines and little or no tertiary amines by the reductive amination of aliphatic alcohols using a metal exchanged crystalline aluminosilicate catalyst. The catalyst has a silica/alumina ratio ranging from about 10:1 to 40:1, contains about 1 to 10% by weight of cobalt or nickel and about 0.05 to 5% by weight of at least one other metal. High conversion rates are achieved at moderate temperatures and pressures.
