Abstract

The invention herein relates to a process for the selective preparation of Para dichlorobenzene, comprising reacting benzene or monochlorobenzene with chlorine in presence of Lewis acid catalyst, at least one inorganic modifier and at least one organic modifier in a reactor. In particular, a process provided in which the para dichlorobenzene is obtained with a selectivity >72% by reacting benzene and chlorine under normal pressure in presence of a new catalyst technology in solution phase with ortho dichlorobenzene <25%, Meta dichlorobenzene <0.025 and trichlorobenzene <2%.
