Background
Ethylbenzene, also known as phenylethane, is an aromatic hydrocarbon that is present in crude petroleum and gasoline. In addition, it is used in industry primarily as a chemical intermediate in the production of styrene monomer. Ethylbenzene has also been used as an industrial solvent and as a diluent in the paint industry as well as in the manufacture of synthetic rubber, acetophenone, and cellulose acetate. Ethylbenzene is present in naphtha, asphalt, and as an impurity in xylene solvents.
