Abstract: A process for preparing copper-chromium catalysts is provided, in which 0.5-3 moles of chromic acid anhydride are dissolved in water, the resulting solution is added and reacted with 1 mole of cupric oxide, 0.1-1 mole (as formaldehyde) of a reducing agent which will be converted into carbon dioxide and water by oxidation is added thereto and reacted, further 0.9-8.0 moles of ammonia are added thereto and reacted, and the resulting product is dried by evaporation and calcined to obtain the desired catalyst.

Abstract: Tertiary monoamines and polyamines are prepared by reacting primary aromatic alcohols, aromatic aldehydes, secondary alcohols, ketones, polyether alcohols, aliphatic or aromatic polyhydric alcohols, polyaldehydes, amino alcohols and ethylene oxide adducts thereof with ammonia, a primary aliphatic amine or a secondary aliphatic amine, in the presence of a homogeneous colloidal catalyst prepared by reducing a mixture of components A and B, provided that at least one of A and B is a carboxylate or a mixture of components A, B and C, wherein A is a copper or solver carboxylate or intramolocular complex, component B is a Group VIII, manganese or zinc carboxylate or intramolecular complex, and component C is a fatty acid or alkali metal or alkaline earth metal carboxylate thereof. The colloidal catalyst permit tertiary amine to be prepared at high yields, without reducing the activity and selectivity of the catalysts.
