Hydrogenation of valeronitrile on a Raney nickel catalyst, gives rise to primary, secondary and tertiary amines, the proportions of which depend on several factors.Synthesis of dipentylimine which is an intermediate in the formation of dipentylamine from valeronitrile was performed.The hydrogenation of this dipentylimine at different hydrogen pressures and in the presence or absence of ammonia, allowed us to explain the modifications of selectivity observed when we varied these two factors during the reduction of valeronitrile.Secondary products formed on the course of the hydrogenation of valeronitrile in the presence of added primary amines (hexylamine or pentylamine) have also been studied.Secondary amines were found consistent with the mechanism proposed and the reversibility of reaction was confirmed.

Hydrogenolysis of N-(1-hexyl)piperidine, N-(1-pentyl)piperidine and 1-pentyl-1-hexylamine on sulphidized CoO-MoO3 catalysts has been investigated.The primary reaction in the hydrogenolysis is the cleavage of the bond between the nitrogen atom and the methylene group of the alkyl substituent or of the methylene ring.Alkylation and transalkylation reactions on the nitrogen play also a role.
