Synthesis of Dimethyl Carbonate from Methyl Carbamate and Methanol Using a Fixed-Bed Reactor

摘要

Several mixed oxide catalysts were prepared by coprecipitation for dimethyl carbonate (DMC) synthesis from methyl carbamate and methanol. During the batch process, the DMC yield was below 35 %. In order to minimize the unfavorable thermodynamic equilibrium and side reactions for the DMC synthesis, a fixed-bed reactor was designed. A maximum DMC yield of ~ 73 % could be realized over a ZnO-Al2O3 catalyst. The effects of reaction conditions for this type of reactor were investigated in detail.
