Styrene - C₈H₈

Styrene, C₈H₈, is a colourless fluid with pungent aromatic smell. The structural formula of styrene is C₆H₅CH=CH₂.

Styrene is used in the production of polystyrene, styrene rubber and styrene plastics. Styrene itself is produced when benzene is alkylated with ethylene to ethylbenzene with aluminium chloride as catalyst. Then you get styrene by dehydrogenation of ethylbenzene.
