Abstract

A process for preparing a copper-modified nickel hydrogenation catalyst comprises mixing a water-soluble copper salt with a water-soluble inorganic alkaline hydroxide in an aqueous solution at a pH high enough to insolubilize the copper salt in the form of suspended copper oxide, admixing the resulting aqueous suspension of copper oxide with a finely divided nickel catalyst, and treating the resulting admixture with gaseous hydrogen to deposit metallic copper on the nickel catalyst. Specified copper salts are sulphate, chloride, nitrate, acetate, formate and cyanide. The nickel catalyst may be supported, e.g. on C, SiO2 or Al2O3 or may be of the Raney-nickel type. Specified alkaline hydroxides are NaOH, KOH, LiOH, Mg(OH)2, Ba(OH)2 and Sr(OH)2. An example describes the hydrogenation of 1,4 butynediol to 1,4 butanediol. U.S.A. Specifications 2,950,326, 2,953,605 and 2,967,893 are referred to.ALSO:Hydrogenation catalysts, prepared by mixing a water soluble copper salt with a water soluble inorganic alkaline hydroxide in an aqueous solution at a pH high enough to insolubilise the copper salt in the form of CuO, admixing the suspended CuO with a finely divided Ni catalyst and reducing the CuO to Cu with hydrogen, are used to reduce aiiphatic and aromatic nitro compounds to amines, ketones and aldehydes to the corresponding alcohols, ethylenic compounds to the corresponding saturated compounds and acetylenic compounds to the corresponding ethylenic or saturated compounds. An example describes the hydrogenation of 1.4 butynediol to 1:4 butanediol. U.S.A. Specifications 2,950,326, 2,953,605 and 2,967,893 are referred to.
