Abstract
A particularly active Raney nickel catalyst is provided with a high-iron content, containing about 10 to 30% by weight of iron relative to the sum of the active metals nickel and iron. The catalyst can be prepared by treating aluminum/nickel/iron alloys which contain (1) 21 to 49.5% by weight of nickel, (2) 3 to 16.5% by weight of iron and (3) aluminum to make up to 100%, with an inorganic or organic base and separating the catalyst from the reaction mixture. According to the invention, said particularly active Raney nickel catalysts are used for the hydrogenation of organic compounds.
