Styrene

Styrene (/ˈstaɪriːn/), also known as ethenylbenzene, vinylbenzene, and phenylethene, is an organic compound with the chemical formula C6H5CH=CH2. This derivative of benzene is a colorless oily liquid that evaporates easily and has a sweet smell, although high concentrations have a less pleasant odor.

Etymology

The term "styrene" is derived from "styrax", the Greek name for the Styrax genus of trees from which the resin was first extracted. The suffix "-ene" signifies that it contains a carbon-carbon double bond.

Production and Uses

Styrene is primarily produced by the dehydrogenation of ethylbenzene. It is an important monomer for the production of polystyrene and several copolymers including ABS and SBR.

Health Effects

Exposure to styrene can cause irritation to the skin, eyes, and respiratory tract. It may also affect the central nervous system, causing headaches, fatigue, weakness, and depression.
