Benzene is an organic chemical compound with a molecular formula of C6H6 and is a natural constituent of petroleum and an essential petrochemical. It is classified as an aromatic hydrocarbon due to its cyclic continuous pi bonds between carbon atoms. Benzene is a colorless, highly flammable liquid with a sweet smell, partially responsible for the aroma of gasoline. It is used primarily as a precursor to the manufacture of more complex chemicals, such as ethylbenzene and cumene, which are produced annually. Benzene is a major industrial chemical, but finds limited use in consumer items due to its toxicity. The word "benzene" derives from "gum benzoin," an aromatic resin known since ancient times in Southeast Asia. Michael Faraday first isolated and identified benzene in 1825 from the oily residue derived from the production of illuminating gas, giving it the name bicarburet of hydrogen. Eilhard Mitscherlich produced benzene by distilling benzoic acid and lime, giving the compound the name benzin. French chemist Auguste Laurent named the substance "phène," which has become the root of the English word "phenol" and "phenyl," the radical formed by abstraction of a hydrogen atom (free radical H•) from benzene. In 1845, Charles Blachford Mansfield, working under August Wilhelm von Hofmann, isolated benzene from coal tar and began the first industrial-scale production of benzene. The chemical family of benzene was eventually recognized as an aromatic hydrocarbon in 1855. In 1997, benzene was detected in deep space.
