Styrene CAS 100-42-5

Styrene is an organic compound formed by replacing one hydrogen atom of ethylene with benzene. The electrons of the vinyl group are conjugated with the benzene ring, which is a kind of aromatic hydrocarbon. Molecular formula C8H8, simple structure C6H5CH=CH2. Exist in Suhe Balsam (a natural fragrance). Colorless, oily liquid with special aroma. Melting point -30.6°C, boiling point 145.2°C, relative density 0.9060 (20/4°C), refractive index 1.546, viscosity 0.762cPat68°F. It is insoluble in water, soluble in ethanol and ether. It will gradually polymerize and oxidize when exposed to the air. Polymerization inhibitor [hydroquinone or tert-butylcatechol (0.0002%～0.002%) must be added for stability Agent to delay its polymerization] can be stored. Industrially, it is an important monomer for synthetic resins, ion exchange resins and synthetic rubbers. Styrene can also undergo addition reactions specific to olefins.
