12,530 PROCESS FOR THE PREPARATION OF EPOXIDES FROM ALKYLENE CARBONATES 12,530 A B S T R A C T A homegeneous catalytic process for converting an alkylene carbonate to the corresponding epoxide wherein a liquid phase comprising said alkylene carbonate and a catalyst is heated at a temperature of from about 100°C to about 250°C to form a product mixture comprising said epoxide and carbon dioxide. The improvement comprises conducting the reaction of alkylene carbonate to epoxide at a pressure below one atmosphere thereby minimizing the formation of undesired aldehyde and/or ketone byproducts.
