Abstract: Preparation of N-substituted cyclic amines of formula (I) comprises reacting primary amines of formula R NH2 (II) with diols of formula HO-A-OH (III) in the presence of hydrogen and a catalyst containing copper obtained by impregnating an inert support with an aqueous solution of an ammine complex of a Cu compound (IV) that readily undergoes thermal decomposition, then drying and calcining to give a catalyst containing 5-50 wt.% Cu, calculated as oxide. A = alkylene or (CH2)n-ÄO-CH2)mÜr (optionally substituted by one or more R ); R , R = alkyl, alkoxyalkyl, optionally alkyl- or alkoxy-substituted cycloalkyl, cycloalkylalkyl, aryl or arylalkyl; n, m = 2-8; r = 1-3.

Abstract: A catalyst (C) consisting of 85-100 wt.% copper oxide and zirconium oxide and 15-0 wt.% metal oxides of groups Ib to VIIb and VIII of the Periodic Table is new. Also claimed is the prepn. of amines by reaction of nitrile with ammonia, or prim. or sec. amine at 80-250 degrees C and 1-400 bar with hydrogen and a catalyst (C). Pref. prepn. of NR1R2-CH2R3 (I) comprises reaction of R3CN with NHR1R2. R1, R2 = H, 1-20C alkyl, 3-12C cycloalkyl, aryl, 7-20C aralkyl, 7-20C alkylaryl; R3 = 1-200C alkyl, 3-12C cycloalkyl, 1-20C alkyl (substd. with NH2, NHMe, NMe2 and/or OH), 2-30C alkoxyalkyl, (CH2-CHR5-O)nR4, aryl, 7-20C aralkyl or 7-20C alkylaryl; n = 2-30; R4 = H, 1-4C alkyl; R5 = H or Me.

Abstract: The present invention relates to a basic mixed carbonate of copper and aluminum of the empirical general composition CumAl6(CO3)0.5mO3(OH)m+12 where m is a number between 2 and 6, as obtained by precipitating, at pH 8 to 9.5 and a temperature of from 60.degree. to 90.degree.C, (a) an aqueous dilute solution of copper and aluminum salts capable of being precipitated by carbonate, the copper and aluminum being present in said solution in an atomic ration of from 2:6 to 6:6, with (b) an aqueous alkali metal carbonate or bicarbonate solution, the atomic concentration of alkali being about twice the concentration of copper and aluminum in said solution. This coppercontaining material dried and annealed for 1 to 8 hours at 350.degree. to 600.degree.C, is suitable as catalyst precursor for the manufacture of butynediol-1,4.
