| titleOfInvention | A kind of preparation method of 2-bromo-3,3,3-trifluoropropene |
| abstract | The present invention relates to a preparation method of 2-bromo-3,3,3-trifluoropropene. The preparation method comprises the following steps: mixing trifluoropropene and liquid bromine, adding a Pd catalyst, and sealing under the condition of 80° C. The tube reaction is carried out for 1-1.5 h to obtain a reaction solution containing 2-bromo-3,3,3-trifluoropropene, and the 2-bromo-3,3,3-trifluoropropene is obtained by distillation and purification. According to the preparation method of 2-bromo-3,3,3-trifluoropropene provided by the present invention, trifluoropropene is used to react under the action of transition metal Pd catalyst, and liquid bromine is used as a bromination reagent. During the reaction, there is no need to add an additional organic solvent, and the reaction time is 1-1.5 h, the reaction time is short, and the reaction yield is high. |
