Title
Propylene carbonate synthesis from propylene glycol, carbon dioxide and benzonitrile by alkali carbonate catalysts
Abstract

The synthesis of propylene carbonate from propylene glycol and carbon dioxide in the presence of various catalysts has been reported. Benzonitrile has been used as both solvent and dehydrating agent. Under optimal conditions, the best results were obtained in the presence of alkali carbonate catalysts. The propylene carbonate yield could reach up to 20% with a propylene-1,2-glycol conversion of 44%.
