| titleOfInvention | The catalyst and its method of synthesizing ethylene carbonate |
| abstract | The present invention relates to a kind of catalyst of synthesizing ethylene carbonate and its method, and it is low mainly to solve the problems, such as that prior art has heterogeneous catalysis activity.The present invention includes major catalyst and co-catalyst by using the catalyst；The major catalyst is alkaline earth metal carbonate；The co-catalyst is organic base R 1 R 2 R 3 X；Wherein, R 1 、R 2 And R 3 It is hydrogen or formula is C a H b Fat-based or aromatic yl group, but R 1 、R 2 、R 3 Hydrogen can not be all, a is any integer in 1~18, and b is any integer in 3~37, and X is N or P；The weight of co-catalyst and major catalyst preferably solves the problem than the technical scheme for 0.1~10, in the industrial production that ethylene carbonate is prepared available for oxirane and carbon dioxide. |
