ABSTRACT

Industrial chlorination of benzene is carried out in the liquid phase at moderate temperature with the aid of a catalyst to produce monochlorobenzene, the three isomeric dichlorobenzenes, and small amounts of the more highly chlorinated derivatives. Chlorobenzene and the 0-and p-dichlorobenzenes are the principal products. The meta-isomer is produced only in minor quantities. The more highly chlorinated derivatives are not normally produced in significant quantities and have only very limited industrial applications.
