Abstract
Hydration of nitriles to amides by reaction of a selected nitrile with water in presence of a solid catalyst selected from copper acetylide or copper nitride is described. The reaction is carried out with the reaction mixture in liquid state contacting the solid catalyst which is preferably in finely divided particulate form. The specific examples describe catalytic hydration of acrylonitrile to make acrylamide.
