PRODUCTION OF UNSATURATED CARBOXYLIC ACID ESTER

摘要

PURPOSE:To produce an unsaturated carboxylic acid ester in a high-space-time yield by a new catalytic preparation method. CONSTITUTION:An olefin is made to react with oxygen and acetic acid in a vapor phase in the presence of a palladium catalyst prepared by subjecting a palladium ammonium complex to ion exchange with the surface hydroxyl group of a catalyst support, then subjecting the ion-exchanged complex to reduction treatment and further carrying an alkali metal acetic acid salt on a catalyst support to produce the objective unsaturated carboxylic acid ester.
