Abstract: Saturated primary amines are prepared by reacting a nitrile with hydrogen at elevated temperature under superatmospheric pressure in the presence of ammonia and a metallic iron catalyst which has been obtained by reducing anisometric iron oxide particles with hydrogen at not more than 500 DEG C.

Abstract: A process for working up mother liquors resulting from the preparation of adipic acid by oxidation of cyclohexanol or cyclohexanone or mixtures thereof with nitric acid entails removal of nitric acid by azeotropic distillation with water, heating the resulting melt at from 130 DEG to 180 DEG C. and then dissolving it in water, treating the aqueous solution with cation exchangers, subsequently again evaporating off the water and heating the resulting dicarboxylic acid melt at from 200 DEG to 240 DEG C. and then obtaining a mixture of dicarboxylic acids by distillation.
