Studies on the Simultaneous Synthesis of Dimethyl Carbonate and Poly (Ethylene Terephthalate): I. Catalytic Activity of Metal Acetate in Transesterification of Ethylene Carbonate with Dimethyl Terepht

A novel direct method for preparation of dimethyl carbonate and poly (ethylene terephthalate) from ethylene carbonate and dimethyl terephthalate has been demonstrated in the presence of metal acetate catalysts, lithium acetate dihydrate showed highest catalytic activity with 47.9% yield of dimethyl carbonate. This method was a green chemical process.
