    Abstract: A process for preparing caprolactam by reacting 6-aminocapronitrile with water in the presence of catalysts comprises using a starting mixture of 6-aminocapronitrile and the tetrahydroazepine derivative of the formulaand conducting the reaction in liquid phase in the presence of a heterogeneous catalyst. Also describes a process for preparing said tetrahydroazepine derivative I and its use for preparing caprolactam and polycaprolactam.

    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 then treating them with an alkali metal hydroxide, using (a) polyvinyl alcohol and water or (b) stearic acid as the auxiliary agent. The invention also concerns 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.

    Abstract: Aliphatic alpha,omega-aminonitriles are prepared by partially hydrogenating aliphatic alpha,omega-dinitriles at an increased temperature and pressure in the presence of a solvent and a catalyst. The catalyst contains (a) a compound based on a metal selected from the group made up of nickel, cobalt, iron, ruthenium and rhodium; (b) 0.01 to 25 % by weight in relation to (a) of a promoter based on a metal selected from the group comprising of palladium, platinum, iridiu m, osmium, copper, silver, gold, chromium, molybdenum. tungsten, manganese, rhenium, zinc, cadmium, lead, aluminium, tin, phosphoru s, arsenic, antimony, bismuth, silicium, titanium, zirconium and rare earth metals; and (c) 0 to 5 % by weight in relation to (a) of a compound based on an alkaline or alkaline-earth metal, provided that component (a) not be based on iron or iron and a metal selected from th e group comprising cobalt, ruthenium and rhodium when (b) is a promoter based on a metal selected from the group comprising titanium, manganese, chromium and molybdenum. Moreover, when component (a) is a compound based only on ruthenium or on rhodium, ruthenium and rhodium, or nickel and rhodium, promoter (b) may be dispensed with.
