Claims
- 1. A process for hydrogenating acetylene-alcohols which comprises: contacting the acetylene-alcohols with a hydrogenation catalyst containing the oxides of the metals nickel, copper and molybdenum, with or without manganese, said catalysts being prepared by precipitating a solution of salts of the metals with an alkali metal carbonate, filtering the resulting suspension and washing, drying and heating the filter residue, wherein an aluminum salt and/or iron salt is added to the metal salt solution, the precipitation is carried out at from 35.degree. to 95.degree. C. and a pH of from 5 to 9 and the heating is carried out at from 350.degree. to 700.degree. C., and the amount of metal salts is so chosen that, after heating, the catalyst consists of from 5 to 70 percent of aluminum oxide and/or iron oxide, the remainder being principally nickel oxide and, based on nickel oxide, from 20 to 40 percent by weight of copper oxide, from 0.5 to 6 percent by weight of molybdenum oxide and from 0 to 10 percent by weight of manganese oxide.
- 2. The process of claim 1, wherein the catalyst, after heating, consists of from 20 to 60 percent by weight of aluminum oxide and/or iron oxide, the remainder being principally nickel oxide and, based on nickel oxide, from 28 to 37 percent by weight of copper oxide, from 1 to 5 percent by weight of molybdenum oxide and from 0 to 8.5 percent by weight of manganese oxide.
- 3. The process of claim 1 or 2, wherein the acetylene-alcohols are hydrogenated at a temperature of from about 40.degree. to 180.degree. C. under a hydrogen pressure of from about 30 to 320 bar.
