Raney nickel catalysts obtainable by a process in which the melt of an alloy comprising 50 to 95 wt.% aluminum, 10 to 50 wt.% nickel, 0 to 20 wt.% iron, 0 to 15 wt.% cerium, cerium mixed metal, vanadium, niobium, tantalum, chromium, molybdenum or manganese and, optionally, further glass-forming elements is allowed to solidify rapidly with a cooling rate of >10<SP>4</SP> K/s and the rapidly solidified alloy is then subjected to a treatment with organic or inorganic bases are described. A process for the preparation of the Raney nickel catalysts mentioned and their use in the hydrogenation of organic compounds, in particular aromatic nitro compounds are furthermore described. |
