摘要
Raney nickel catalysts obtainable by a process in which the melt of an alloy comprising 50 to 94 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 104 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.
