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, wherein the catalytically active mass of the catalyst contains, after its preparation and before the treatment with hydrogen, 22 to 45% by weight of oxygen-containing compounds of zirconium, calculated as ZrO.sub.2, 1 to 30% by weight of oxygen-containing compounds of copper, calculated as CuO, 5 to 50% by weight of oxygen-containing compounds of nickel, calculated as NiO, where the molar ratio of nickel to copper is greater than 1, 5 to 50% by weight of oxygen-containing compounds of cobalt, calculated as CoO, 0 to 5% by weight of oxygen-containing compounds of molybdenum, calculated as MoO.sub.3, and 0 to 10% by weight of oxygen-containing compounds of aluminum and/or manganese, calculated as Al.sub.2 O.sub.3 or MnO.sub.2.
