Abstract
A method and a device for purifying 1,4-bis (bromodifluoromethyl) benzene are disclosed. In order to solve the problem of hard to purify and separate 1,4-bis (bromodifluoromethyl) benzene crude products, diphenylmethane that has a higher boiling point and does not interact with 1,4-bis (bromodifluoromethyl) benzene is mixed with the 1,4-bis (bromodifluoromethyl) benzene crude products for evaporation. Afterwards, the purity of the vaporized product is detected and only that reaching an expected purity is collected to obtain high-purity 1,4-bis (bromodifluoromethyl) benzene.
