Styrene NEW

Styrene is an organic compound formed by replacing one hydrogen atom of ethylene with benzene, and the electron of vinyl is conjugated with the benzene ring, which is a kind of aromatic hydrocarbon. Molecular formula C8H8, simple structure C6H5CH=CH2. It's found in balsam, a natural fragrance. A colorless, oily liquid with a distinctive aroma. Melting point -30.6℃, boiling point 145.2℃, relative density 0.9060(20/4 ℃), refractive index 1.5469, viscosity 0.762cPat68°F. Insoluble in water, soluble in ethanol, ether, exposed to the air gradually polymerization and oxidation, to add the inhibitor [hydroquinone or tert-butylcatechol (0.0002% ~ 0.002%) as a stabilizer to delay its polymerization] can be stored. In industry, it is an important monomer of synthetic resin, ion exchange resin and synthetic rubber. Styrene can also undergo addition reactions characteristic of olefins.
