Synthesis method of 1, 1, 2, 3, 3, 3-hexafluoropropyl methyl ether

The invention discloses a synthesis method of 1, 1, 2, 3, 3, 3-hexafluoropropyl methyl ether. The method includes the steps of: adding methanol, a solvent, a catalyst and a ligand into a reaction kettle, introducing hexafluoropropylene under stirring and starting reaction, with the mole ratio of methanol to hexafluoropropylene being 1-10:1, the mass ratio of the solvent to hexafluoropropylene being 1-20:1, the mole ratio of the catalyst to hexafluoropropylene being 0.01-0.2:1, and the mole ratio of the catalyst to the ligand being 1:1-6, controlling the reaction temperature at 30-150DEG C andthe reaction pressure at 0.1-2MPa, stopping introducing hexafluoropropylene, then further carrying out reaction for 2-24h, and at the end of the reaction, conducting cooling, discharging and distillation, thus obtaining 1, 1, 2, 3, 3, 3-hexafluoropropyl methyl ether. The synthesis method of 1, 1, 2, 3, 3, 3-hexafluoropropyl methyl ether provided by the invention has the advantages of no use of strong base, simple process,
