4-Chloro-3-nitrobenzenesulfonic acid synthesis

8synthesis methods
It is derived from the nitration of p-chlorobenzenesulfonic acid. Add p-chlorobenzenesulfonic acid and 98% sulfuric acid into the reaction pot, cool to 20°C, add 67% nitric acid solution under stirring, react at 40°C for half an hour, salt out, filter, acidify, and filter to obtain the finished product. 4-Chloro-3-nitrobenzenesulfonic acid was synthesized by
