スチレン

スチレンは、無色からわずかに黄色を帯びた油状液体で、刺激的で甘くフローラルな臭気を持ち、揮発性が高い。沸点は145 ℃、融点は−30 ℃である。スチレンは芳香族炭化水素であり、ビニル置換ベンゼンであるとともに、主要な有機化学中間体に分類される。スチレンは主に重合されてポリスチレン樹脂および共重合体（アクリロニトリル・ブタジエン・スチレン（ABS）、スチレン・アクリロニトリル（SAN）、スチレン・ブタジエンゴム（SBR）など）が製造され、これらは包装材、自動車部品、建築材料、消費財などに広範に使用されている。また、スチレンは不飽和ポリエステル樹脂における反応性希釈剤としても用いられ、船舶、輸送機器、産業用機器などに使われるガラス繊維強化プラスチック（FRP）の製造にも利用される。

Styrene is an important monomer of synthetic rubber, adhesives and plastics. [3,4,5] It is used for the synthesis of styrene butadiene rubber and polystyrene resin, polyester glass fiber reinforced plastics and coatings. It is used for preparing polystyrene, ion exchange resin, and foam polystyrene. It is also used for copolymerization with other monomers to produce various engineering plastics, such as copolymerization of acrylonitrile and butadiene to produce ABS resin, widely used in various household appliances and industries. Copolymerization with acrylonitrile, obtained SAN is a resin with shock resistance and bright color. The SBS produced by copolymerization with butadiene is a thermoplastic rubber, which is widely used as a polyvinyl chloride and acrylic modifier. SBS and SIS thermoplastic elastomers are made with butadiene and isoprene copolymerization, and as a crosslinking monomer, styrene is used in the modification of PVC, polypropylene, and unsaturated polyester.Syrene is used as a hard monomer for the production of styrene acrylic emulsion and solvent pressure sensitive adhesive. Emulsion adhesive and paint can be prepared by copolymerization with vinyl acetate and acrylic ester. Styrene is one of the most commonly used vinyl monomers in the scientific field, used in various modified and composite materials.[6]In addition, a small amount of styrene is also used as perfume and other intermediates. By chloromethylation of styrene, cinnamyl chloride is used as an intermediate for the non anesthetic analgesic strong pain determination, and styrene is also used as an antitussive, expectorant and anticholinergic original medicine in stomach Changning. It can be used to synthesize anthraquinones dye intermediates , pesticide emulsifiers, and styrene phosphonic acids ore dressing agent and copper plating brighteners.[7]
