Abstract: A supported catalyst (I) containing 0.1-20 wt.% rhenium and 0.05-10 wt.% platinum (with respect to the total weight of the catalyst) is prepared by: (a) treatment of the optionally pretreated support with a solution of a rhenium compound; (b) drying and heating in a reducing atmosphere at 80-600 degreesC and; (c) impregnation with a solution of a platinum compound and drying. An Independent claim is also included for a process for the production of alcohols by catalytic hydrogenation of carbonyl compounds using the catalyst (I).

Abstract: A process for the preparation of caprolactam is provided, whereina) a mixture (I) containing 6-aminocapronitrile and water is reacted in the liquid phase, in the presence of a catalyst, to give a mixture (II) containing caprolactam, ammonia, water, high-boiling components and low-boiling components,b) ammonia is then removed from the mixture (II) to give a mixture (III) containing caprolactam, water, high-boiling components and low-boiling components,c) water is then removed from the mixture (III) to give a mixture (IV) containing caprolactam, high-boiling components and low-boiling components, andd) a solid (V) containing caprolactam is then obtained from the mixture (IV) by crystallization, the proportion by weight of caprolactam in the solid (V) being greater than in the mixture (IV).

Abstract: A process for removing high boilers from crude caprolactam which comprises high boilers, caprolactam and in some cases low boilers, and which has been obtained by a) reacting 6-aminocapronitrile with water to give a reaction mixture b) removing ammonia and unconverted water from the reaction mixture to obtain crude caprolactam, which comprises c) feeding the crude caprolactam to a distillation apparatus to obtain a first substream via the top as a product and a second substream via the bottom, by setting the pressure in the distillation in such a way that the bottom temperature does not go below 170° C., and adjusting the second substream in such a way that the caprolactam content of the second substream is not less than 10% by weight, based on the entire second substream.
