| titleOfInvention | A kind of preparation method of 4,4- difluorinated ethylene carbonate |
| abstract | The present invention relates to a kind of preparation methods of 4,4- difluorinated ethylene carbonate.Mainly include the following steps: that (1) vinylidene fluoride by epoxidation reaction, obtains 1,1- difluoro ethylene oxide；(2) 1,1- difluoro ethylene oxide and carbon dioxide reaction obtain 4,4- difluorinated ethylene carbonate.Compared with prior art, obtained product has higher selectivity and yield to the preparation method, and raw material vinylidene fluoride is cheap and easy to get, remarkable in economical benefits, is suitable for industrialized production. |
