Summary:
The present invention discloses a synthetic method of 4-trifluoromethyl ethylene carbonate. Add urea and 3,3, 3-trifluoro-1, 2-propanediol with a molar ratio of 1:1 to 1:4 to the reaction vessel, heat to melt it, and then add a catalyst that accounts for 0.6% to 5% of the total mass of 3,3, 3-trifluoro-1, 2-propanediol and urea, and heat the above mixture to 150°C to 190°C for reaction, the reaction system was vacuumed to 0 ~-0.04MPa, the generated by-product ammonia was discharged, the reaction was cooled to room temperature for 1~6h, and solid-liquid separation and rectification purification were carried out to obtain 4-trifluoromethyl vinyl carbonate product. The invention has the advantages of mild reaction conditions, simple process, economy and environmental protection.
