Ethylbenzene

A component of paint formations and associated with some carpeting, ethylbenzene off-gases in the home, in office furniture products, in office buildings, and in a subject’s breath. Ethylbenzene is considered a chronic toxin.

Ethylbenzene

 

C6H5CH2CH3, a colorless liquid with a boiling point of 136.2°C, a melting point of –94.97°C, and a density of 0.867 g/cm3 at 20°C. Ethylbenzene is almost insoluble in water, but it dissolves in ethanol, benzene, ether, and carbon tetrachloride.

Ethylbenzene is found in petroleum and coal tar. It is usually produced industrially from benzene and ethylene by the Friedel-Crafts reaction. By passing ethylbenzene vapors over catalysts, styrene is produced; styrene is used as a raw material in the production of important industrial products, including certain types of plastics (seePOLYSTYRENE) and synthetic rubbers. Ethylbenzene is also used in organic synthesis; for example, acetophenone is produced by the liquid-phase catalytic oxidation of the hydrocarbon. Ethylbenzene is also used as a solvent and component of high-octane gasolines. The maximum permissible concentration of ethylbenzene vapor in the air is 0.05 mg per liter.
