Beschreibung
Zusammenfassung:	A modified Raney catalyst having a high activity and a high selectivity can be prepared by forming, by a mechanical alloying method, a Raney alloy comprising three components or four or more components represented by the formula Al-Me-X wherein Me is one metal selected from the group consisting of Ni, Co, Fe, Cu, Pd and Ag; and X is different from Me and is at least one metal selected from the group consisting of Ag, Co, Pt, Ti, V, Cr, Fe, Cu, Zn, Ge, W, Re, Os, Ir, Au, Zr, Nb, Mo, Ru, Rh, Pd, Cd, In, Sn and Sb, and then leaching the Raney alloy.
