| titleOfInvention | A kind of preparation method of fluoro ethylene carbonate with high purity |
| abstract | The invention discloses a kind of preparation methods of fluoro ethylene carbonate with high purity.The preparation method comprises the steps of: that (1) crude product fluorinated ethylene carbonate must synthesize: using dried metal fluoride and chlorocarbonic acid vinyl acetate as raw material, the maintaining reaction temperature under the effect of high polymer three phase catalyst synthesizes crude product fluorinated ethylene carbonate at 20 DEG C ~ 50 DEG C；(2) purifying of crude product fluorinated ethylene carbonate: reaction solution can obtain the sample that purity is greater than 99.95% after the processes such as filtering, distillation, recrystallization, rectification under vacuum.High polymer three phase catalyst is used in this method, reaction condition is mild, and high catalytic efficiency, product are easily purified, and catalyst recycling is simple reusable. |
