ABSTRACT:
A molten Raney copper alloy containing copper and a metal selected from Al, Si and Zn as major components and, if necessary, specific metals as minor components is solidified at a cooling rate of not less than 1.times.10.sup.2 K/sec by a rotary water atomizing process, water or gas atomizing process, single roll process or similar process. The Raney copper alloy thus obtained is leached to obtain a Raney copper catalyst. The resultant catalyst exhibits activity several times higher than that of conventional Raney copper catalysts in the reaction of acrylonitrile with water to give acrylamide.
