styrene

styrene;vinylbenzene
CAS 100-42-5


nature : also known as vinyl benzene. Colorless liquid-fuel easily. A strong aroma and refraction. Melting point HSNSI ÿ?C Boiling Point 145.2 ÿ?C The relative density of 0.9059. Refractive index of 1.5467. Flash point (open cup) 31.11 ÿ?C Spontaneous point 490 ÿ?C Do not dissolve in water, soluble in alcohol and ether. Polymerization can have with the other monomer (1-butene) copolymer. Hydride can play and halogenated role. Exposed air gradually undergoing polymerization and oxidation. When exposed to heat or sunlight, or in the presence of peroxidase easy polymerization, the simultaneous release of energy, and can cause an explosion. Explosion limits of 1.1% ~ 6.1% (vo1). Industrial mainly ethylene and benzene alkylation generation ethylbenzene, ethylbenzene via catalytic dehydrogenation obtained. Another part of ethylbenzene and styrene from propylene oxide production, which also received styrene and propylene oxide two products. Styrene monomer is important that the Department used in the manufacture of polystyrene resins, styrene-butadiene rubber, thermoplastic elastomer, ABS engineering plastics, unsaturated polyester and ion exchange resin.
