PROCESS FOR THE MANUFACTURE OF UNSATURATED ESTERS OF CARBOXYLIC ACIDS

摘要

Unsaturated esters of carboxylic acids are prepared by reacting olefins or cycloolefines with carboxylic acids and oxygen in the gaseous phase in the presence of a catalyst containing noble metal salts or noble metals of the VIIIth group of the Periodic System and alcali metal salts and/or alcaline earth metal salts, as activators the content of noble metal being in the range of from 1.2 to 5% by weight and the proportion of the metal fraction of each individual activator to the noble metal content being in the range of from 0.5 to 1 to 3 : 1.
