Benzene (C6H6) is a hydrocarbon, the simplest aromatic hydrocarbon, which is a sweet, flammable, carcinogenic, colorless, transparent liquid at room temperature with a strong aromatic odor. It is hardly soluble in water, soluble in organic solvents, and itself as an organic solvent. The ring system of benzene is called benzene ring, and the structure after benzene ring is removed by one hydrogen atom is called phenyl group, which is represented by Ph. Therefore, the chemical formula of benzene can also be written as PhH. Benzene is a basic petrochemical industry

Therefore, the chemical formula of benzene can also be written as PhH. Benzene is a basic raw material for petrochemical industry. Its production level and technical level of production are one of the indicators of the development level of a national petrochemical industry.

On October 27, 2017, the World Health Organization’s International Agency for Research on Cancer published a preliminary list of carcinogens, benzene in a list of carcinogens.
