Abstract
The invention relates to a method for producing a bis(trifluoromethyl)benzene. This method includes the steps of (a) chlorinating a compound represented by the general formula (1) by chlorine, thereby to produce a trichloromethyltrifluoromethylbenzene; and (b) fluorinating the tricbloromethyltrifluoromethylbenzene by hydrogen fluoride, thereby to produce the bis(trifluoromethyl)benzene, ##STR1## where m is 1, 2 or 3. It is not necessary in the invention to handle solid in any reaction step. Therefore, the invention is very useful in the production of a bis(trifluoromethyl)benzene in an industrial scale
