still for oxacylering of olefins with up to 4 carbon atoms, by omsettning between a karbonsyra - up to 4 carbon atoms, and oxygen in the gaseous phase in nervaro of a palladiumsalt - based catalyst on berare

摘要

Improvement of a process for the oxacylation of olefins in the gaseous phase in the presence of carrier catalysts containing palladium salts and additives by adding a barium carboxylic acid aurate the carboxylic acid part of which contains from 2 to 10 carbon atoms.
