Investigation of Carbonate Dimethyl Ester Production from Propylene Carbonate and Methanol on Calcium Cerium-based Catalysts

The calcium cerium based catalysts with different proportions were prepared by the sol gel method, and their transesterification performance for the synthesis of dimethyl carbonate from propylene carbonate and methanol was studied. The catalyst activity was evaluated using a three necked flask with a serpentine condenser tube, and the reaction products were analyzed using the internal standard method.

The catalyst was characterized using XRD, N2 adsorption and desorption, FT-IR, XPS, and CO2-TPD, and analyzed using Origin to study the structure activity relationship of the catalyst.
