Nitrobenzene is an organic compound with the chemical formula C6H5NO2. It is a water-insoluble pale yellow oil with an almond-like odor. It freezes to give greenish-yellow crystals. It is produced on a large scale from benzene as a precursor to aniline. In the laboratory, it is occasionally used as a solvent, especially for electrophilic reagents. WebThe introduction of a further nitro group to give 1,3,5-trinitrobenzene requires a prolonged reaction time. The bromination and chlorination of nitrobenzene is achieved by reaction with the appropriate halogen in the presence of a suitable catalyst ( p. 46 ).
