What is Benzene Styrene?

Benzene Styrene is an organic compound formed by replacing a hydrogen atom of ethylene with benzene. The electrons of the vinyl group are conjugated with the benzene ring. It is a kind of aromatic hydrocarbon. Molecular formula C8H8, simple structural formula C6H5CH=CH2. Exist in Suhe balsam (a natural spice). 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 1.5469, viscosity 0.762cPat68°F. Insoluble in water, soluble in ethanol and ether, gradually polymerized and oxidized when exposed to the air, and should be stabilized by adding a polymerization inhibitor [hydroquinone or tert-butylcatechol (0.0002% to 0.002%) agent to delay its polymerization] before storage. Industrially, it is an important monomer of synthetic resin, ion exchange resin and synthetic rubber. Benzene Styrene can also undergo addition reactions unique to alkenes.

In industry, Benzene Styrene can be prepared by catalytic dehydrogenation of ethylbenzene. It can be obtained by heating cinnamic acid in the laboratory.

As early as 1850, it was known that Benzene Styrene does not react with natural resins but polymerizes. But it wasn’t used industrially until the 1830s, when styrene was produced by dehydrogenating styrene (a compound of ethylene and benzene extracted from gasoline). In 1937, German Farben and American Dow Chemical Company carried out the industrial production of Benzene Styrene by using ethylbenzene dehydrogenation method. During World War II, production expanded rapidly due to the need to produce synthetic rubber. After the war, styrene production skyrocketed due to the development of Benzene Styrene-based plastics, and several other production methods emerged. For example: In 1966, the American Haakon Company developed the ethylbenzene co-oxidation method; in the early 1970s, Japan and other countries used extractive distillation to separate styrene from pyrolysis gasoline, and the amount of styrene produced depended on the scale of ethylene production. In 1981, the total capacity of Benzene Styrene devices in the world reached 17.13Mt, of which more than 90% were manufactured by the catalytic dehydrogenation of ethylbenzene.
