1,4-Bis(trichloromethyl)benzene explained

1,4-Bis(trichloromethyl)benzene is an organic compound with the formula C6H4(CCl3)2. A white solid, it is prepared industrially by chlorination of para-xylene. It reacts with terephthalic acid to give terephthaloyl chloride, a precursor to Kevlar. It also reacts with sulfur dioxide to give the same acid chloride and thionyl chloride.[1] It reacts with hydrogen fluoride in 1,2-dichloroethane to form 1,4-bis(chlorodifluoromethyl)benzene in a yield of 79%.[2]
