Before the treatment with hydrogen, in the catalytically active material, the zirconium-containing compound 22 to 40% by mass (calculated as ZrO 2 ), the copper oxygen-containing compound 1 to 30% by mass (calculated as CuO) 15 to 50% by mass of nickel-containing compound (calculated as NiO) (however, the molar ratio of nickel to copper exceeds 1), 15 to 50% by mass of oxygen-containing compound of cobalt (calculated as CoO) And catalysts containing less than 1% by weight of alkali metal (calculated as alkali metal oxide), and in the presence of the catalyst, primary or secondary alcohols, aldehydes or ketones can be increased at elevated temperatures and Producing amines by reacting with hydrogen and nitrogen compounds selected from the group of primary and secondary amines at elevated pressures Method. |
