Anwendungen

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.

Bemerkungen

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