Abstract
Process for the preparation of saturated primary fatty amines by hydrogenation of the corresponding unsaturated primary fatty amines In the novel process, the hydrogenation of the double bonds in an unsaturated primary fatty amine is achieved by reaction of the unsaturated primary fatty amine with hydrogen at a temperature of 80.degree. to 160.degree. C. and a pressure of 1 to 40 bar in the liquid phase and in the presence of 0.1 to 10% by weight of a nickel catalyst or cobalt catalyst. If the fatty amine to be hydrogenated contains ammonia, the latter is substantially removed before the hydrogenation process.
