ABSTRACT:
Benzoyl chloride is prepared by a process in which the high-boiling residue obtained in the catalytic oxidation of toluene with oxygen or oxygen-containing gases in the liquid phase is largely freed of heavy metal salts which are present, and is then chlorinated at elevated temperatures, optionally under the action of light, and the benzoyl chloride is then separated off.
