Styrene is an organic compound that can be formed by both benzene and ethylene. It is a colorless and transparent liquid that is very easy to contaminate drinking water, soil and surface water, and has strong volatility and is easily volatile under light environment, so it is often stored and transported in steel drums. Currently it is widely used in synthetic resins and rubber, such as polystyrene, ABS resin and other engineering plastics.

　　Production process of styrene

　　Currently, there are two methods of making styrene, namely ethylbenzene co-oxygenation and ethylbenzene dehydrogenation, in which ethylbenzene is the main raw material for producing styrene, and benzene and ethylene produce ethylbenzene. In the ethylbenzene co-oxygenation method, ethylbenzene and propylene are the main raw materials, ethylbenzene reacts with oxygen to produce a peroxide, and then the peroxide reacts with propylene in an oxidation reaction, and finally the resulting product is distilled to obtain styrene by dehybridization. In the case of ethylbenzene dehydrogenation, a catalyst is needed, and then the reaction is carried out in a reactor, and finally the dehydrogenation process and distillation separation process are carried out to obtain pure styrene.

　　Application of Styrene

　　Styrene can be used as synthetic rubber and resin, the most common finished products are styrene-butadiene, ABS resin, polystyrene, styrene-butadiene rubber is the main raw material, styrene content is different, but also will lead to different properties of styrene-butadiene rubber, so styrene-butadiene rubber material in the content of strict requirements, ABS resin must be known, is a kind of high strength and high toughness of the resin. Styrene can be mixed with acrylonitrile and butadiene to form ABS resin, which is widely used in the field of home appliances and automobiles. Polystyrene, a direct product of styrene, polystyrene along the transparency of styrene, its glass transition temperature up to 100 & deg; ℃ C, excellent adiabatic properties, can be used for disposable packaging, automotive materials.
