1,1,2,2-Tetrafluoroethyl-2,2,2-trifluoroethyl ether, an environmentally friendly solvent, used as a cleaning agent, a desiccant, and an auxiliary for removing dust or non-condensable gases. It can be synthesized from Tetrafluoroethylene and 2,2,2-Trifluoroethanol in diethylene glycol dimethyl ether with potassium hydroxide reaction for 4.8 h, yield 98%.
Yield:406-78-0 98%
Reaction Conditions:
potassium hydroxide in diethylene glycol dimethyl ether;water at 50; under 1500.15 Torr; for 4.8 h;Product distribution / selectivity;Cooling with liquid nitrogen;
Steps:
7
The test of the reaction was carried out in the same manner as in Example 6 except that diglyme was used instead of tetraglyme. The reaction time was 4.8 hours, and no TFEO was present in the obtained reaction solution. The yield was 98%.
