发明名称 PROCESS FOR THE PRODUCTION OF OLEFIN ACID ANHYDRIDES AND ESTERS THEREOF
摘要 The present invention concerns a method for the production of olefin anhydrides, such as acrylic anhydride and methacrylic anhydride, via reactions between an aromatic acid chloride, such as benzoyl chloride, and carboxylate ions of the olefin acid corresponding to the anhydride to be produced. The method of the invention may be conducted without the use of a solvent, catalyst, polymerization inhibitor, or an external source of heat. Moreover the acrylic anhydrides of the invention can be used to produce high yields of acrylate esters by means of room-temperature reactions, without mineral acid catalysis.
