Description
Styrene Monomer (SM)
Styrene monomer is a pale yellow to pale yellow color like aromatic substances. In low concentrations, this substance has a sweet smell and flowers, and at high concentrations, it has an odorant and permeable odor. The styrene monomer is very volatile and has a low solubility in water (300 mg/liter of water at 20 ° C), but in petrol and benzene, ethanol is also soluble in ethanol, methanol, diethyl ether, acetone, and toluene. The boiling point of styrene is 146 degrees Celsius and its specific weight is 0.9 grams per cubic centimeter. This aromatic hydrocarbon is an oil that quickly evaporates and has a pleasant smell.
Application of styrene monomer
Styrene monomer used in painting and polystyrene coatings as a thermoplastic. Styrene is a high-monomer in the production of plastics and resins, such as polystyrene resins, copolymers such as:
- styrene acrylonitrile (SAN), benzene denial styrene copolymers, styrene-butadiene-styrene (SBR), acrylonitrile butadiene styrene (ABS) latex, Unpolished polyester (styrene) and polystyrene.
Methods of Styrene Monomer Production
Styrene is produced in the industry from ethylbenzene, which is widely used in benzene-alkenylation with ethylene.
Laboratory method: This method is the first method used to generate styrene. In the laboratory, cyanoacrylate is produced from styrene acid.
