Abstract
Chlorinated derivatives of benzene are obtained by passing a mixture of benzene or a partially chlorinated benzene and chlorine through a reaction zone at a temperature of 375-700 DEG C., the space velocity employed being less than 100 reciprocal minutes when working in the temperature range 650-700 DEG C. Catalysts, such as the well-known chlorine carriers, iodine, aluminium chloride and ferric chloride may be used. In examples chlorine and benzene or monochlorbenzene are led through a silica tube at varying temperature and space velocities yielding mixtures containing mono-, di- and trichlorbenzene; at temperatures above 500 DEG C., chlorinated diphenyls are also obtained. Specification 342,329 is referred to.
