Стирол

A three dimensional model of aromatics. Molecular formula C8H8, structure simplified C6H5CH = CH2. Co-exist in the Soviet Union balm (a natural flavor), the. Colorless, with special aroma of oily liquid. Melting point -30.6 °C, boiling point 145.2 °C, relative density 0.9060 (20 / 4 °C), refractive index 1.5469, viscosity 0.762 cP at 68 ° F. Insoluble in water (<1%), with ethanol, ether and other organic solvents miscible. Styrene at room temperature, which can slow polymerization inhibitor to be increased [tert-butyl hydroquinone or catechol (0.0002% 0.002%) as stabilizer, in order to delay the polymerization] can be stored. Poly Styrene from polystyrene resin generated, it can with other unsaturated compounds copolymerized to produce synthetic rubber and resins and other products. For example, styrene butadiene rubber and styrene butadiene copolymer; ABS resin is acrylonitrile (A), butadiene (B) and styrene (S) copolymer; ion exchange resin material is styrene [1] and a small amount of 1,4 - bis (vinyl) benzene copolymer. Styrene can also occur on specific olefin addition reaction. In industry, styrene catalyzed by ethylbenzene dehydrogenase obtained. Laboratory can be heated acid approach.
