Abstract
PURPOSE: To make the deactivated catalysts containing metallic copper (produced by decomposing copper hydride), used for producing meth)acrylamide by the catalytic hydration of (meth)acrylonitrile, recover their activity and filterability at the same time by impregnating them with an aq. solution of e.g. specific metallic salts.
