use

It is a dye intermediate, used as a color-protecting agent for vat dyes, sulfur dyes, dyes and dyes, and can be used as a rust inhibitor and electroplating nickel-removal agent for ships.

production method

In the enamel kettle, first add 350 parts of fuming sulfuric acid, control the kettle temperature 0 ~ 5 °C, slowly add nitrobenzene under stirring, add 132 parts of nitrobenzene in 1h after the kettle temperature is raised to 100 °C, insulation 2h. Samples were taken to determine the sulfonation end point (1 to 2 drops of material were dropped into a 10 ml test tube filled with clean water and no turbidity was demonstrated until the end point). After the sulfonation reaction is completed, it is cooled, slowly added to ice water, and added in about 3 hours.
2 000 parts of salt, salting out several hours later, standing overnight, suction filtration, pressure drying, intermediates between nitrobenzene sulfonic acid. Into 500 parts of hot water, m-nitrobenzene sulfonic acid was boiled and dissolved. Remove a small amount of sulfone. Add 50 parts of soda ash to neutralization and then add active carbon to decolorize. Heat and filter. The filtrate is cooled and crystallized. The filter cake is washed with a small amount of water and dried at below 50°C to obtain the finished product.
