With 1H-imidazole; 1,2-dibromohexafluoropropane; water; at 50 - 120℃; under 15001.5 Torr; for 28h;Autoclave; | Adding a moisture content of 4000 ppm in a 50 mL stainless steel autoclave equipped with agitation3,3,3-trifluoropropylene oxide (33.6 g, 0.3 mol), 3-bromo-1,1,1-trifluoro-2-propanol (2.3 g, 12 mol),2,3-dibromo-1,1,1,2,3,3-hexafluoropropane (5.6 g, 18 mol), imidazole (1.6 g, 24 mmol),After sealing, the reactor was replaced twice with CO2, and the stirring was set to a reaction temperature of 120 C.Continuously pass CO2 to maintain the reaction pressure at 2MPa, react for 4h, cool to normal temperature, and slowly releaseTo the excess CO2 gas, 50% water of a molar amount of 3,3,3-trifluoroepoxypropane was added to the reaction solution, and the reaction was stirred at 50 C for about 24 hours to obtain 3,3,3-trifluoro. Crude product of propylene carbonate and 3,3,3-trifluoro-1,2-propanediol, analysis of reaction product distribution by gas chromatography, separation,Refined process to get the target product3,3,3-trifluoropropene carbonate and42.3 g of 3,3,3-trifluoro-1,2-propanediol was used to calculate the yield |
