Abstract
Acrylamide may be prepared by the hydrolysis of acrylonitrile by treating the acrylonitrile with water in the presence of a copper catalyst which has been prepared by volatilizing copper metal at a temperature in the range of from about 1000.degree. to about 1500.degree. C. in vacuo and condensing the vapors in the presence of an organic solvent.
Claims11
A process for the preparation of acrylamide which comprises treating acrylonitrile with water at hydrolysis conditions in the presence of a catalyst comprising finely divided metallic copper and prepared by volatilizing copper metal, subsequently cooling the copper vapors in contact with an organic solvent and heating to ambient temperature, and recovering the resultant acrylamide.
