Benzene 45 (organic compound)

Benzene,with the chemical formula C6H6,formerly known as benzene,xylene,cyclohexane,etc.,is an aromatic hydrocarbon that is flammable,volatile,has a special aromatic odor,and is a colorless liquid at room temperature.Benzene is highly toxic.On October 27,2017,the International Agency for Research on Cancer of the World Health Organization released a preliminary list of carcinogens,and benzene was listed as a Group 1 carcinogen.
Benzene is the simplest aromatic hydrocarbon,difficult to dissolve in water,easily soluble in organic solvents,and can also be used as an organic solvent.Benzene is a basic raw material in the petrochemical industry,and its production volume and technological level are indicators of the development level of the country's petrochemical industry.The ring system of benzene is called the benzene ring,which is the simplest aromatic ring.The structure of a benzene molecule after removing one hydrogen atom is called a phenyl group,represented by Ph;Therefore,benzene can also be expressed as PhH.
