Abstract
Amines are prepared by reacting aldehydes or ketones at elevated temperature under elevated pressure with nitrogen compounds selected from the group of ammonia, primary and secondary amines, and with hydrogen in the presence of a catalyst containingcopper, wherein the catalytically active mass of the catalyst contains, before the reduction with hydrogen,20 to 85% by weight of oxygen-containing compounds of zirconium, calculated as ZrO2,1 to 30% by weight of oxygen-containing compounds of copper, calculated as CuO,14 to 70% by weight of oxygen-containing compounds of nickel, calculated as NiO,0 to 5% by weight of oxygen-containing compounds of molybdenum, calculated as MoO3,and 0 to 10% by weight of oxygen-containing compounds of aluminum, calculated as Al2O3.
