Abstract:
The present invention relates to a facile method of preparing 1,4-bis(chlorodifluoromethyl)benzene, comprising the steps of: (A) providing a reactant liquid of 1,4-bis(difluoromethyl)benzene; optionally (B) providing a light source for UV radiation; and (C) introducing chlorine gas into the reactant liquid at a temperature of 50-90° C. under a pressure above 1 atm to obtain 1,4-Bis(chlorodifluoromethyl)benzene. The invented facile method can be utilized in a batch process or a continuous process for effective production of 1,4-bis(chlorodifluoromethyl)benzene.
