Abstract
p-Toluenesulfonyl chloride was synthesized by taking toluene as raw material .In the reaction of sulfonation, the azeotropic water removing, sulfuric acid was used as sulfonating agent . In the reaction of chlorination, carbon tetrachloride was used as agent, and chlorine gas as chlorinating agent. By using this technique, the use ratio of sulfuric acid was higher, and operating cost was lower.
