Uses
4-Nitrobenzenesulfonyl chloride (CAS NO.98-74-8) is commonly used as a medicine and dyes intermediates.
Production
Mixed 60g 4, 4'-dinitro-diphenyl disulfide, 300ml concentrated hydrochloric acid and 60ml concentrated nitric acid, heated to 80 °C, which leads to chlorine reaction. At the end of the reaction, dump out the resulting chloride, washed with 80 °C water, get the crude, after acetic acid recrystallization may get 72g product.
