专利号:US-3674848-A 优先权日:1970-08-19 标题 :Hydration of nitriles using metal salts of cation exchange resins 发明人:SCHOENBRUNN ERWIN FREDERICK; SINHA VINOD TARKESHWAR 权利人:AMERICAN CYANAMID CO 摘要:Solid catalysts for hydration of nitriles to amides comprise metal salts of cation exchange resins. Group I B and II B metals are used with either strong acid or weak acid cation exchange resins. A variety of organic nitriles may be used in the process. Detailed examples describe preparation of several catalysts and the synthesis of acrylamide, acetamide and benzamide. The reactants in liquid solution are contacted with the solid catalyst at 70* - 180* C.
