Abstract

PURPOSE: The reaction of p-toluenesulfonic acid with chlorine is carried out in the presence of water, an inert solvent and sulfure to produce title compound which is important as the starting material of 2,4-dichlorobenzoyl chloride and intermediate of agricultural and medical chemicals inexpensively in high yield.
CONSTITUTION: Title compound is obtained by reaction of p-toluenesulfonic acid with chlorine in the presense of an inert solvent, e.g., carbon tetrachloride or tetrachloroethane, water (preferably 0.1W3.0wt%) and sulfur (preferably 0.5W1.5 moles per mole of p-toluenesulfonic acid) at 30W100°C.
EFFECT: The process is simplified and unnecessary for a specific chlorination catalyst, thus giving economic and technical advantages.
