The catalytic hydrogenation of nitriles of synthetic fatty acids is one of the methods of preparing higher primary aliphatic amines. This work is devoted to an analysis of the factors which affect the selectivity of this process in the direction of obtaining primary amines and which are connected primarily with the strength of adsorption of intermediate reaction products on transition metals. The hydrogenation of capronitrile was selected as a model. To study the effect of the nature of metallic catalysts on their activity and selectivity, we prepared and tested the following catalysts: nickel, cobalt, rhodium, osmium, platinum, and palladium, supported on industrial ..gamma..-aluminum oxide. Characteristics of the catalysts tested are given.
