B15C5 was readily converted to the highly pure 4′ chlorosulfonylbenzo 15 crown 5(2) by chlorosulfonation with chlorosulfonic acid at ambient temperature,then reduction of the sulfonyl chloride moiety in 2 with zinc and sulfuric acid provided the 4′ mercaptobenzo 15 crown 5 in good yield.

Synthesize 2-methyl-5-acetamino benzene sulfochloride using p-toluidine as primer reactant by aceylation and chlorosulfonation.

During the chlorosulfonation of N-acetanilide to p-acetamidobenzenesulfonyl chloride,sodium sulphate was added in late stage.

In the reaction of chlorosulfonation carbon tetrachloride was used as solvent,adding the sodium chloride in later stage reaction.

To improve the synthetic technology,albendazole is synthesized from carbendazole by sulfochlorination,reduction of iron powder and thiolation under alkalinious catalyst condition.

2,4-Dichloro-5-sulfamoylbenzoic acid(1)was synthesized by sulfochlorination, ammoniation and hydrolysis with 2,4-dichlorobenzoic acid as raw materials, and the reaction conditions were optimized.
