Abstract
Solid catalyst of reduced copper magnesium silicate type is improved for its use in catalytic hydration of acrylonitrile to make acrylamide by calcining the catalyst prior to such use. Calcining strengthens the catalyst particles for longer catalyst life in the reactor and slows the rate of decay of catalytic activity so the average productivity over the life of the catalyst is improved.
