ABSTRACT OF THE DISCLOSURE Continuous preparation of mono- or di-(trichloromethy)- benzenes or of mono- or di-(trichloromethyl)-benzenes substitut- ed in the benzene ring by halogen a?oms from the corresponding mono- or dimethylbenzenes and chlorine in several steps with radiation by means of rays of high energy, by reacting mono- or dimethylbenzene with chlorine in 4 to 14 steps, at a temperature in the range of from 20 to 130°C, whereby chlorine is introduced into the second step and the following steps, the resulting waste gas is introduced into step 1 and chlorine contained in the waste gas is reacted in reactor 1 with fresh mono- and di- methylbenzene. A preferred embodiment for carrying out the process is the reaction in a reactor arrangement in cascade form, wherein the number of steps corresponds to the number of reac- tors and wherein as reactors circulation reactors are used. The mono- and di-(trichloromethyl)-benzenes are valuable intermediates for the preparation of pesticides, textile auxiliaries and dye- stuffs.
