METHOD FOR MANUFACTURING 2,2,2-TRIFLUOROETHYL DIFLUOROMETHYL ETHER

摘要

PURPOSE: A method is provided which manufactures 2,2,2-trifluoroethyl difluoromethyl ether simply and in a high yield by reacting CF3CH2OH with CHCl3 and HF under the existence of a catalyst. CONSTITUTION: In a method for manufacturing 2,2,2-trifluoroethyl difluoromethyl ether, the method is characterized in that CF3CH2OH is reacted with CHCl3 and HF under the existence of a catalyst, that is, chlorides, fluorides or oxides of a metal selected from the group consisting of B, Sn, Ti, Al, Zn, and Ce, wherein an amount of the catalyst is 0.005 to 1 mole per one mole of trifluoroethanol, wherein an amount of CHCl3 is 1 to 10 moles per one mole of trifluoroethanol, wherein an amount of HF is 5 to 50 moles per one mole of trifluoroethanol, and wherein a temperature of the reaction is 100 to 200 deg.C.
