Abstract: The invention concerns the simultaneous preparation of caprolactam and hexamethylene diamine from adipodinitrile, by the following steps: (a) the adipodinitrile is partially hydrogenated, producing a mixture substantially containing 6-aminocapronitrile, hexamethylene diamine, ammonia, adipodinitrile and hexamethylene imine (= "the mixture"); (b) the mixture obtained in step (a) is distilled, producing ammonia, as the forerunnings, and a residue I, in the presence of a compound A which is inert in the distillation conditions, the ammonia not being separated totally; (c) the residue I, substantially containing "the mixture", inert compound A and ammonia, the ammonia content being less than that of the mixture used in step (b), is subjected to a second distillation, producing a mixture of the inert compound A and ammonia, as the forerunnings, and a residue II; (d) the base II, substantially containing "the mixture" and inert compound A, is subjected to distillation in a third column, producing the inert compound A, as the forerunnings, and a residue III; (e) the base III, substantially containing "the mixture" and optionally an inert compound B, is subjected to distillation in a fourth column, producing forerunnings KP1, which substantially contain hexamethylene imine, optionally inert compound B and hexamethylene diamine, and a residue IV; (f) the forerunnings KP1 are subjected in a fifth column to distillation, producing forerunnings KP2, which substantially contain hexamethylene imine and optionally inert compound B, and a residue V, which substantially contains hexamethylene diamine with a degree of purity of at least 95 %, the forerunnings KP2 being fed to the third column or optionally only partially fed to the third column, and the rest being discarded; and (g) the residue IV, substantially containing 6-aminocapronitrile and adipodinitrile, is subjected in a sixth column to distillation, producing 6-aminocapronitrile with a degree of purity of at least 95 %, as forerunnings, and adiponitrile in the residue. The resultant 6-aminocapronitrile is cyclized to form caprolactam.

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 solvent and of a catalyst by a process which comprises using a catalyst which (a) contains a compound based on a metal selected from the group consisting of nickel, cobalt, iron, ruthenium and rhodium and (b) contains from 0.01 to 25% by weight, based on (a), of a promoter based on a metal selected from the group consisting of palladium, platinum, iridium, osmium, copper, silver, gold, chromium, molybdenum, tungsten, manganese, rhenium, zinc, cadmium, lead, aluminum, tin, phosphorus, arsenic, antimony, bismuth and rare earth metals and (c) from 0 to 5% by weight, based on (a), of a compound based on an alkali metal or on an alkaline earth metal. with the proviso that the component (a) is not based on iron or iron and one of the metals selected from the group consisting of cobalt, ruthenium and rhodium when (b) is a promoter based on a metal selected from the group consisting of titanium, manganese, chromium and molybdenum, and with the further proviso that, when a compound based on only ruthenium or rhodium or ruthenium and rhodium or nickel and rhodium is selected as component (a), the promoter (b) may be dispensed with.

Abstract: The invention concerns a method of producing compounds containing NH2 groups by the hydrogenation of compounds which include at least one carbon-nitrogen bond with hydrogen in the presence of a catalys t, at a temperature not below room temperature and at an elevated hydrogen partial pressure optionally in the presence of a solvent. The hydrogenation is carried out under the following conditions: a) a catalyst containing cobalt and/or iron is used b) if the yield, based o n the compound being hydrogenated, and/or the selectivity, based on the desired product, drops below a defined value or if the amount of an undesired side-product increases to more than a defined value, the hydrogenation is interrupted by stopping the feed of the compound being hydrogenated and, if present, also the solvent, c) the catalyst is treated with hydrogen at a temperature in the range 150 to 400.degree.C, using a hydrogen pressure of 0.1 to 30 MPa and a treatment time of 2 to 48 h and d) the hydrogenation is subsequently continued, and the catalysts containing cobalt and/or iron are regenerated.

Abstract: The invention concerns the production of a hydrogenation catalyser based on an aluminium/transition metal alloy. The proposed method involves producing a kneadable material from the alloy and an auxiliary agent, moulding the kneadable material into moulded articles, calcinating these articles and the n treating them with an alkali metal hydroxide, using (a) polyvinyl alcohol an d water or (b) stearic acid as the auxiliary agent. The invention also concern s methods of hydrogenation and hydrogenolysis, in particular the partial hydrogenation of aliphatic .alpha.,.omega.-dinitriles to .alpha.,.omega.- aminonitriles; and the use of the catalysers thus produced for hydrogenation and hydrogenolysis.
