| 英文摘要 | Dimethyl carbonate (DMC) is a useful chemical and can substitute some toxic substances. The synthesis of DMC from methanol and urea is an attractive route, but is a thermodynamically unfavourable reaction. Enhancing the equilibrium conversion of the reaction is an intereting topic. In this study, we demonstrate that poly(ethylene glycol) diglyceryl ether (PEGDE, a poly(ethylylene glycol) based bis-diol), which is a non-toxic and cheap polymer, can be used as a functional medium for the synthesis of DMC from methanol and urea using ZnO as the catalyst. In the PEGDE/ZnO catalytic system, PEGDE reacted with urea to form poly(ethylene glycol) di(2,3-carbonateglyceryl)ether (PEGDC), and the reaction equilibrium was shifted by sweeping away the generated ammonia. Then, DMC was produced after methanol was added and PEGDE was regenerated and the PEGDE/ZnO catalytic system could be reused directly. It was shown that a very high equilibrium yield could be achieved. |
