Application | 2-bromo-3, 3, 3-trifluoropropene has superior performance as fire extinguishing agent, refrigerant and other materials, compared with the widely used fire extinguishing materials such as trifluoromethane and heptafluoropropane, its performance is much superior, so it is an ideal substitute for halon. In addition, 2-bromo-3, 3, 3-trifluoropropene, as an important fluorine-containing block, is also widely used in the field of organic synthesis. |
preparation | (1) 1.6g of mesoporous sulfonic acid and 160g(1mol) of liquid bromine were added with a thermometer, in the three bottles of the air duct and the reflux condenser, the temperature is raised to 35 ° C. With stirring, and 91.2g(0.95mol) of 3,3, 3-trifluoropropene is introduced, and about 2H is passed through, the reaction was continued to be stirred at a temperature of 35 ° C. For 0.5h, cooled to room temperature, and the catalyst was filtered off to obtain a reaction solution. The filtered catalyst can be reused. (2) in the three bottles with thermometer, constant pressure dropping funnel and atmospheric distillation device, add 25% sodium hydroxide aqueous solution 200g, stir and raise the temperature to 75 ℃ ~ 85 ℃, Dropwise add step (1) the obtained reaction solution was simultaneously distilled to receive a fraction at 32 to 36 ° C. To obtain 2-bromo-3, 3, 3-trifluoropropene. |
