Abstract

A process for the manufacture of carboxylic acid amides by addition reaction of water with nitriles in the presence of a catalyst which contains copper and magnesium silicate and has been treated with a reducing gas, to which catalyst cement of a certain particle size has been admixed. The amides obtainable by the process are starting materials for the manufacture of solvents, flocculants, wetting agents, pesticides, crop protection agents, textile assistants, e.g. brighteners, water repellent agents, foam stabilizers and detergents.
