The utilization of glycerol for the synthesis of added value chemicals is a theme of great industrial interest because glycerol is formed as by-product in large amounts during the production of biodiesel from natural triglycerides. Commercial lipase, Novozym 435 was used to produce the benign monomer glycerol carbonate from renewable starting materials: glycerol and dimethyl carbonate. Tetrahydrofuran was used as the reaction medium to enhance the formation rate of glycerol carbonate and conversion approached quantitative yield. Removal of methanol produced as by-product during reaction increased the yield of glycerol carbonate. Other by-products such as glycerol dicarbonate and diglycerol tricarbonate were found. However the total amount of by-products was minute compared with that of glycerol carbonate, which means that lipase-catalyzed reaction is very regioselective for the synthesis of glycerol carbonate.
