Synthesis of Dimethyl Carbonate from Propylene Carbonate and Methanol Using Imidazolium Salt Catalysts |
| 초록 |
The synthesis of dimethyl carbonate (DMC) was investigated through the transesterification of propylene carbonate (PC) with methanol using imidazolium salt catalysts. The reaction was carried out in an autoclave at 140 - 180 oC under carbon dioxide pressure of 200 - 1000 psig. The main by-product was propylene glycol (PG). The imidazolium salts of smaller alkyl group, and more nucleophilic exhibited higher catalytic activity. The conversion of PC increased as CO2 pressure and reaction temperature increased. Kinetic studies are also performed to better understand the reaction mechanism. |
