Abstract: Aliphatic alpha ,w-dinitriles with a phosphorus content of 1.0 ppm or more by weight (ppm wt.) are used for the production of alpha ,w-aminonitriles by partial hydrogenation in presence of a special iron-based catalyst containing a promoter based on aluminium, silicon, zirconium, titanium and/or vanadium. A process for the production of aliphatic alpha ,w-aminonitriles comprises the partial hydrogenation of corresponding dinitriles with a phosphorus content of 1.0 ppm wt. or more in presence of a catalyst containing (a) iron and/or an iron compound, (b) 0.01-5 wt% (based on a) of a promoter based on 2, 3, 4 or 5 elements selected from Al, Si, Zr, Ti and V, and (c) 0-0.5 wt% of an alkali or alkaline earth metal compound. An Independent claim is also included for catalysts with the above composition obtained by the reduction and optional passivation of magnetite, showing a BET surface of 3-10 m /g, a total pore volume of 0.05-0.2 ml/g and an average pore diameter of 0.03-0.1 micron, with 50-70% (by volume) of the pores in the range from 0.01 to 0.1 microns.

Abstract: The invention relates to a method for separating by distillation all or part of an imine (III) from a mixture (II) containing an amine (I) and an imine (III). Said method is characterized in that a compound (IV) which under distillation conditions is inert in relation to the amine (I) and whose boiling point under distillation conditions lies above the boiling point of the amine, is added to the distillation mixture, and that distillation yields a mixture (VI) which essentially contains a compound (IV).

Abstract: The invention concerns a process for simultaneously preparing 6-aminocapronitrile and hexamethylene diamine proceeding from adipodinitrile. The process is characterized in that: (1) adipodinitrile is partially hydrogenated in the presence of a catalyst in order to obtain a mixture containing 6-aminocapronitrile, hexamethylene diamine and adipodinitrile; (2) 6-aminocapronitrile and hexamethylene diamine are separated from the mixture; (3) between 0.01 and 10 wt %, relative to adipodinitrile, of an acid or an acidic ion exchanger is added to the part substantially containing adipodinitrile, and the adipodinitrile is separated from the mixture; and (4) the adipodinitrile is returned to step (1).
