    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 ZrO2,1 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 MoO3, and 0 to 10% by weight of oxygen-containing compounds of aluminum and/or manganese, calculated as Al2O3 or MnO2.

    Abstract: Preparation of mono- or polyfunctional tertiary amines of formula X(CH2NR1R2)n (I) involves reacting a nitrile of formula (R1R2NCH2)n-mX(CN)m (II) with a secondary amine of formula NHR1R2 (III) and hydrogen. The reaction is at 50-250 degrees C and 5-350 bars, in presence of a palladium-based catalyst (IV), comprising (based on total catalyst) 0.1-10 wt.% palladium and 0.01-10 wt.% of at least one other metal, selected from Group IB and VIII elements, cerium and lanthanum, on a carrier. In (I)-(III), R1, R2 = 1-20C alkyl, 3-8C cycloalkyl, 4-20C alkylcycloalkyl, 4-20C cycloalkylalkyl, aryl, 7-20C alkaryl, 7-20C aralkyl, 2-8C hydroxyalkyl, 2-8C mercaptoalkyl or 8-20C aryloxyalkyl; or R1 + R2 = optionally unsaturated 2-6C alkylene chain (optionally substituted by 1-3 1-4C alkyl and optionally interrupted by O); X = n-valent 1-20C alkyl, 2-20C alkenyl or 3-8C cycloalkyl group (optionally substituted by 1-20C alkyl, 3-8C cycloalkyl, 4-20C alkylcycloalkyl, 4-20C cycloalkylalkyl, 2-20C alkoxyalkyl, aryl, 7-20C alkaryl, 7-20C aralkyl, 1-20C alkoxy, OH, 1-20C hydroxyalkyl, 1-20C alkylamino, 2-20C dialkylamino, 2-12C alkenylamino, 3-8C cycloalkylamino, arylamino, diarylamino, aryl-(1-8C)alkylamino, halo, SH, 2-20C alkenyloxy, 3-8C cycloalkoxy, aryloxy or 2-8C alkoxycarbonyl); n = 1-4; and m = 1 to n. Also claimed is the use of (IV) as catalyst for the reaction of secondary amines with nitriles and hydrogen to give tertiary amines in general.
