3-Nitrobenzenesulfonic acid, sodium salt is used for the manufacture of: textile, leather or fur, fabricated metal products, chemicals and electrical, electronic and optical equipment.
Release to the environment of 3-Nitrobenzenesulfonic acid, sodium salt can occur from industrial use: in processing aids at industrial sites, in the production of articles, as an intermediate step in further manufacturing of another substance (use of intermediates), of substances in closed systems with minimal release and as processing aid.

Production Method    
Industrial production can be obtained by sulfonation and neutralization of nitrobenzene. Raw material consumption quota: benzene (98%)400 kg/t, sulfuric acid (98%)550 kg/t, nitric acid (98%)390 kg/t, liquid alkali (30%)500 kg/t, fuming sulfuric acid (containing SO 320%)410 kg/t, lime milk 550 kg/t, soda ash (95%)30 kg/t.
In enamel kettle, 350 parts of fuming sulfuric acid are added first, the temperature of the kettle is controlled to 0~5 ℃, nitrobenzene is slowly added under stirring, 132 parts of nitrobenzene are added within 1h, then the temperature of the kettle is raised to 100 ℃, and the temperature is kept for 2h. 
Sampling to measure the sulfonation end point (drop 1~2 drops of materials into 10ml test tube filled with clear water, and no turbidity proves to reach the end point). 
After the sulfonation reaction is completed, it is cooled, slowly added into ice water, and 2,000 parts of salt are added in about 3 hours. 
After salting out for several hours, it is left to stand overnight, sucked and filtered, and pressed to dry to obtain the intermediate m-nitrobenzene sulfonic acid. 
Put m-nitrobenzene sulfonic acid into 500 parts of hot water, boil and dissolve. 
Remove a small amount of sulfone. 
Add 50 parts of soda ash to neutralize and then add activated carbon to decolorize, filter while hot, and cool and crystallize the filtrate. 
The filter cake is washed with a small amount of water and dried below 50 ℃ to obtain the finished product.
