Ethylbenzene is a colorless, flammable liquid with a sweet, gasoline-like odor. It is naturally found in products such as coal tar and crude petroleum. Ethylbenzene is primarily used as a chemical intermediate to produce styrene. In smaller quantities, ethylbenzene is also used as a solvent in common products like rubber, inks, insecticides, paints, and in fuels.
