Abstract

PURPOSE: To obtain the titled compound at a high reaction rate in a high conversion with the inhibited formation of a tarry substance as a by-product, by oxidizing chlorotoluene with a gas containing molecular oxygen in the presence of a reaction product and a catalyst containing Co, Mn and Br without using a solvent.
CONSTITUTION: o-or m-Chlorotoluene is oxidixed with a gas containing molecular oxygen to prepare the corresponding chlorobenzoic acid. In the process, a catalytic system containing Co, Mn and Br essentially is used, and chlorobenzoic acid which is the aimed product in an amount of 20wt% or more based on the raw material chlorotoluene is present in the reaction system to carry out the reaction at 120W200°C, preferably 130W180°C. Preferably the amounts of the Co, Mn and Br are as follows: 0.02W0.7wt%, expressed in terms of Co metal, based on the chlorotoluene, Co compound, 2W20wt%, expressed in terms of Mn metal, based on the Co metal, Mn compound and a Br compound in an amount of 2W5 times that of Co metal expressed in terms of Br atom.
