Chlorobenzene is an aromatic organic compound with the chemical formula C6H5Cl. It is a colorless, flammable liquid first made in 1851 by reacting phenol and phosphorus pentachloride.
Chlorobenzene has been used in the manufacture of certain pesticides, most notably DDT by reaction with chloral (trichloroacetaldehyde). It also once found use in the production of phenol. However, use of these manufacturing processes has declined significantly in the past few decades. Today the major use of chlorobenzene is as an intermediate in the production of nitrochlorobenzenes and diphenyl oxide, which are important in the production of commodities such as herbicides, dyestuffs, and rubber.
Chlorobenzene is also used as a high-boiling aprotic solvent in organic chemistry, as a solvent for paints, and for degreasing automobile parts.
