Abstract
An improved process for making acrylamide from a composition of acrylonitrile and water utilizing an improved Raney copper catalyst which contains from about 2 to 45 weight percent of aluminum on a 100 weight percent total weight basis. Preferably, this catalyst is prepared under low temperature, and/or slow caustic addition conditions from a copper aluminum alloy. The process can be practiced continuously for extended periods of time at high reaction rates and high conversion yields even when employing concentrated acrylonitrile starting feeds.
