Dimethyl carbonate(DMC) was synthesized from EC and methanol using a heterogeneous basic catalyst. A series of heterogeneous catalysts were prepared and their activities were evaluated. After intensive studies on the synthesis of DMC by a transesterification between EC and MeOH, we have found that DMC can be very effectively synthesized by using K/MgO as a solid base catalyst impregnated with K2CO3 aqueous solution. EC conversion of 52.9% and DMC yield of 52.5% were obtained at 80oC. These values were very close to those of K2CO3 which was well known as efficient homogeneous base catalyst for DMC synthesis. In addition, due to the heterogeneous character of K/MgO, the catalyst could be easily separated from reactants/products and be regenerated efficiently. |
