Use Nitrobenzene is an important organic intermediate thereof. Nitrobenzene was sulfonated with sulfur trioxide to obtain m-nitrobenzene sulfonic acid. It can be used as a dye intermediate, mild oxidant and anti-dye salt s. Nitrobenzene was sulfonated with chlorosulfonic acid to obtain m-nitrobenzenesulfonyl chloride, which was used as intermediate of dye, medicine and so on. Nitrobenzene is chlorinated to M-nitrochlorobenzene, which is widely used in the production of dyes and pesticides. After reduction, M-chloroaniline can be obtained. Used as a dye orange GC, is also a pharmaceutical, pesticide, fluorescent whitening agent, organic pigment intermediates. Nitrobenzene re-nitration can be m-dinitrobenzene, by reduction can be m-phenylenediamine, used as dye intermediates, epoxy resin curing agent, petroleum additives, Cement accelerator, M-dinitrobenzene such as sodium sulfide for part also principle to M-nitroaniline. For the dye orange base R, is an intermediate of azo dyes and organic pigments.
