The invention discloses a method for synthesizing 1,2-dimethoxy-1,1,2,2-tetrafluoroethane, and relates to the technical field of battery electrolyte additives. The synthetic method of 1,2-dimethoxy-1,1,2,2-tetrafluoroethane, its synthetic steps are as follows: S1: pass into the four-necked flask with stirrer, thermometer and condensation reflux device Nitrogen was used to replace the air inside, then the solvent was added to the four-necked flask, the stirrer and condensed water were turned on, and then 1,2-dihydroxy-1,1,2,2-tetrafluoroethane, methanol and The catalyst was added into a four-necked bottle to obtain mixed solution A. The synthesis method of the present invention is relatively simple, and is suitable for industrial production. At the same time, the reaction process is simple, there is no intermediate in the reaction process, and the reaction by-product is less, so the subsequent separation of the reaction product is convenient to obtain a higher purity 1,2-dimethoxy-1,1,2,2-tetrafluoroethane, high-purity 1,2-dimethoxy-1,1,2,2-tetrafluoroethane for subsequent applications . |
