Abstract
A process for producing secondary alkyl primary amines having from 10 to 50 or, from about 10 to about 13, or from about 14 to 50 carbon atoms from crude n-paraffin oximes derived by the photonitrosation of C.sub.10 to C.sub.50 or C.sub.10 to C.sub.13 or C.sub.14 to C.sub.50 n-paraffins, said process comprising hydrogenation in a polar solvent in the presence of ammonia and a metal catalyst. The crude n-paraffin oximes are contaminated with ketones and nitroso halides. By the process of this invention, these impurities are likewise converted into the corresponding secondary alkyl primary amines.
