An homogeneous catalytic oxychlorination reaction of aromatic hydrocarbons was carried out on H202 as catalyst on HCI oxidation for chlorine for chlorination process in situ. Presence of Ar-H in the medium shifted the oxidation rate of the HCl through bond breaking in the Ar-H-Cl upon which chlorine distribution was· found to be dependent on H202 concentration, .and temperature. Increase in HCI concentration beyond 30% showed significant effect on the rate of chlorine liberation but no influence on chlorine distribution in the Ar-H, except on branched hydrocarbon groups. Temperature profile showed that 99% of the available chlorine was liberated between 40 55°C while only 98% of the liberated chlorine reacted with the aromatic hydrocarbons. Above 60°C over 400/o of the liberated chlorine dissolve in the inorganic phase as a result of evaporation of the Ar-H from the reaction zone at that temperature.
