Mix and stir o-Chloroaniline, concentrated hydrochloric acid and glacial acetic acid, cool to below 0℃, add sodium nitrite solution dropwise, add SO2 glacial acetic acid solution containing copper chloride after diazotization reaction, and react for 1.5h. Then ice separation was performed and extracted with ether. The extract was washed with alkali water until neutral, dried, evaporated to remove ether, and finally the fraction was collected by decompression distillation at 96-98℃ (0.133kPa) to obtain 2-Chlorobenzenesulfonyl Chloride.
