Abstract:
A method for producing 1,4-bis(difluoromethyl)tetrafluorobenzene is disclosed, which has the following steps: (a) mixing 1,4-bis(dichloromethyl)tetrafluorobenzene, a catalyst, an aprotic polar solvent, and an alkali metal fluoride to form a reaction mixture; (b) heating the reaction mixture; and (c) purifying the resultant to obtain 1,4-bis(difluoromethyl)tetrafluorobenzene.
