Abstract: A method for the N-alkylation of amines by reacting alcohol with (di)alkylamine in the presence of hydrogen is carried out in the presence of a catalyst based on copper and magnesium silicate, which contains 0-2 wt.% each of barium oxide, chromium (III) oxide (Cr2O3) and/or zinc oxide. Also claimed is the use of this catalyst for N-alkylation of amines.

Abstract: A new catalyst (I) contains 0.01-30 wt% ruthenium or palladium as active metal, optionally together with Group I, VII or VIII transition metal(s), on a carrier (II) in which (novel feature) 10-50% of the pore volume consists of macropores with a pore diameter (PD) of 50-10,000 nm and 50-90% consists of mesopores with a PD of 2-50 nm. Also claimed are (i) a process for conversion of polymers containing multiple C-C bond(s) in presence of (I) and (ii) a process for conversion of organic compounds in the presence of (I) in which the active metal is ruthenium.

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: Hydrogenation of an aromatic ring containing at least one OH or amino group in the presence of a catalyst comprising at least one group I, VII or VIII metal and a carrier is characterised in that the catalyst is prepared by: (a) dissolving the active component of the catalyst or its precursor in a solvent; (b) treating the solution with an organic polymer that in situ binds at least 10 times its weight in water to give a swollen polymer; (c) mixing the polymer with the catalyst support material; and (d) shaping the mass, drying and calcining.
