Description and Uses
Chlorobenzene is a colorless liquid with analmond-like odor. The odor threshold is between 0.1 and3.0 μg/L. Also reported in the literature at 0.68 and0.741 ppm. Molecular weight=112.56; Boilingpoint=131-132℃; Freezing/Melting point=2 45℃;Flash point=28℃; Autoignition temperature=593℃.Flammable limits are: LEL=1.3%; UEL=9.6%. HazardIdentification (based on NFPA 704 M Rating System):Health 2, Flammability 3, Reactivity 1. Insoluble in water.
Chlorobenzene is a halogenated benzene that is used as a solvent for paints, as a heat transfer medium, and in the manufacture of phenol, aniline and nitrochlorobenzenes. Now chlorobenzene is mainly used as a solvent for pesticide formulations, diisocyanate manufacture, degreasing automobile parts, and for the production of nitrochlorobenzene and chemical toxicity QSAR research for agricultural pollution.
