Abstract: Aliphatic alpha,omega-aminonitriles are prepared by partial hydrogenation of aliphatic alpha,omega-dinitriles at elevated temperatures and superatmospheric pressure in the presence of a base and of a hydrogenation catalyst, by carrying out the hydrogenation in the presence of ammonia and lithium hydroxide or of a compound which gives lithium hydroxide during the hydrogenation.

Abstract: A process for distillative separation of part or all of an imine (III) from a mixture (II) comprising an amine (I) and said imine (III) comprises adding to the distillation mixture a compound (IV) which is inert toward said amine (I) under distillation conditions and whose boiling point is above the boiling point of said amine (I) under said distillation conditions to obtain, after the distillation, a mixture (VI) comprising essentially said compound (IV).
