Benzene (also called cyclohexatriene) is an organic chemical compound with the molecular formula C6H6. Benzene is a natural constituent of crude oil and is one of the elementary petrochemicals.
Benzene is used mainly as an intermediate to make other chemicals, above all ethylbenzene, cumene, cyclohexane, nitrobenzene, and alkylbenzene and also used to make some types of rubbers, lubricants, dyes, detergents, drugs, explosives, and pesticides.

Benzene is a key raw material in the production of plastics such as polystyrene, polyethylene, and nylon, as well as synthetic fibers such as polyester and nylon. It serves as a building block in chemical reactions to produce monomers, which are then polymerized to form these materials.
Benzene is classified as a carcinogen by regulatory agencies such as the International Agency for Research on Cancer (IARC) and the U.S. Environmental Protection Agency (EPA). Chronic exposure to benzene can lead to serious health effects such as leukemia, lymphoma, and other blood disorders. Benzene emissions from industrial processes and vehicle exhaust also contribute to air pollution and environmental contamination.
Benzene is primarily produced through the catalytic reforming of naphtha, a mixture of hydrocarbons obtained from crude oil refining. The reforming process involves heating naphtha in the presence of a catalyst to break down larger hydrocarbon molecules into smaller aromatic compounds, including benzene. Benzene can also be produced as a byproduct of other chemical processes, such as ethylene production in steam cracking.
Regulatory agencies such as the Occupational Safety and Health Administration (OSHA) and the EPA have established regulations and guidelines to limit occupational exposure to benzene in workplaces and to control benzene emissions from industrial sources. These measures include permissible exposure limits (PELs), emission standards, and monitoring requirements to protect workers and the environment from the health hazards of benzene.
