| Abstract: | Mesoporous solid base was prepared by loading KI,K 2CO 3 and KOH on active carbon,and was used as catalyst for synthesis of dimethyl carbonate by transesterification of propylene carbonate (PC) and methanol. Effects of base strength,catalyst content,temperature and mole ratio of methanol to PC on the reaction as well as regeneration of the catalyst were investigated. |
