Production Method of Sodium 3-Nitrobenzenesulfonate: 

Sulfonation method: nitrobenzene is sulfonated with sulfuric acid to produce 3-nitrobenzene sulfonic acid. This method needs to use a lot of sulfuric acids and sodium hydroxide; the cost is high and will produce a lot of wastewater and waste gas, causing environmental pollution.

Chlorination: the chlorination reaction of nitrobenzene with chlorination agent (such as phosphorus pentachloride) to produce 3-nitrochlorobenzene, and then hydrolysis reaction with sodium hydroxide to produce 3-nitrobenzene sulfonate. This method requires using phosphorus pentachloride and other toxic substances, causing environmental pollution, more by-products, and low yield.

Oxidation method: phenol or sodium phenol is oxidized with nitric acid to produce sodium 3-nitrobenzene sulfonate. This method requires a large amount of nitric acid and phenol or sodium phenol; the cost is high, causing environmental pollution.

Esterification method: nitrobenzene is esterified with dimethyl sulfate or diethyl sulfate to produce 3-nitrobenzoate methyl ester or 3-nitrobenzoate ethyl ester and then hydrolyzed with sodium hydroxide to produce 3-nitrobenzoate sodium. This method requires a large amount of dimethyl sulfate, diethyl sulfate, and sodium hydroxide; the cost is high and will produce a lot of wastewater and waste gas, causing environmental pollution.
