A process for dehydrogenating 1,4-butanediol to .gamma.-butyrolactone in the gas phase in the presence of a copper-containing catalyst, wherein the catalyst contains 4-40% by weight of copper and 0-5% by weight of Na.sub.2 O, based on the total weight of the catalyst, on a carrier consisting of 80-100% by weight of SiO.sub.2 and 0-20% by weight of CaO.

Dehydrogenation of 1,4-butanediol to .gamma.-butyrolactone

In a process for the hydrogenation of multiply unsaturated C.sub.2 -C.sub.8 hydrocarbons, in particular C.sub.2 -C.sub.8 -alkynes and/or C.sub.4 -C.sub.8 -alkynenes and/or C.sub.4 -C.sub.8 -alkadienes in fluids comprising these by contact with a catalyst packing in the presence of free hydrogen, the catalyst packing can be produced by applying at least one substance which is active as catalyst and/or promoter to woven or knitted meshes or foils as support material.

Hydrogenation process

N-Substituted cyclic amines are prepared by reacting diols with primary amines over a copper-containing catalyst which is obtainable by impregnation of an inert support with an aqueous solution of an ammine complex of a readily thermally decomposable copper compound and subsequent drying and calcination and contains from 5 to 50% by weight of copper, calculated as CuO.
