Applicazioni

Nitrobenzene is used as a solvent and as a starting material in the organic synthesis for the preparation of aniline, benzidine, azobenzene, nitrosobenzene, phenylhydroxylamine and acetaminophen. It is also used as a solvent for electrophilic reagents in synthetic chemistry. Further, it is used to prevent the unpleasant odor in shoe, floor and metal polishes. It acts as a precursor to rubber chemicals, azo dyes and pharmaceuticals.

Note

Incompatible with strong oxidizing agents, strong reducing agents and strong bases.

For selective reduction to phenylhydroxylamine with hydrazine hydrate in the presence of rhodium, see: Org. Synth. Coll., 8, 16 (1993).

Electrophilic iodination of the deactivated ring has been effected with N-Iodosuccinimide, A14320, in triflic acid: J. Org. Chem., 58, 3194 (1993).

Commonly used, high dielectric constant solvent, e.g. in Friedel-Crafts reactions. CAUTION! Exothermic reactions can occur with aluminum chloride.
