Chemical Properties:

Styrene ndi madzi firiji, colorless, ndi fungo lamphamvu, styrene ndi choyaka, otentha mfundo 145.2 digiri Celsius, kuzizira mfundo -30.6 digiri Celsius, yeniyeni yokoka 0,906, styrene ndi insoluble m'madzi, ngati 25 digiri Celsius, styrene solubility ndi 0.066% yokha. Styrene imatha kusakanizidwa ndi ether, methyl ferment, carbon disulfide, acetone, benzene, toluene ndi tetra-ironic carbon mugawo lililonse. Styrene ndi chosungunulira chabwino cha mphira wachilengedwe, mphira wopangidwa ndi zinthu zambiri zachilengedwe. Styrene ndi poizoni ndipo angayambitse poizoni ngati thupi la munthu litakoka mpweya wochuluka wa styrene. Mlingo wololedwa wa styrene mu mpweya ndi 0.1mg/L. Mpweya wa styrene ndi mpweya zidzapanga chisakanizo chophulika.

Ntchito:

Styrene ndi monomer yofunika kwambiri ya mphira wopangira, zomatira ndi mapulasitiki. [3,4,5] Amagwiritsidwa ntchito popanga mphira wa styrene butadiene ndi utomoni wa polystyrene, mapulasitiki opangidwa ndi galasi la polyester ndi zokutira. Amagwiritsidwa ntchito popanga polystyrene, ion exchange resin, ndi thovu polystyrene. Amagwiritsidwanso ntchito pa copolymerization ndi ma monomers ena kupanga mapulasitiki osiyanasiyana aumisiri, monga copolymerization ya acrylonitrile ndi butadiene kupanga utomoni wa ABS, womwe umagwiritsidwa ntchito kwambiri pazida zosiyanasiyana zapakhomo ndi m'mafakitale. Copolymerization yokhala ndi acrylonitrile, yopezedwa ndi SAN ndi utomoni wokhala ndi kugwedezeka komanso mtundu wowala. SBS yopangidwa ndi copolymerization ndi butadiene ndi rabala ya thermoplastic, yomwe imagwiritsidwa ntchito kwambiri ngati polyvinyl chloride ndi acrylic modifier. SBS ndi SIS thermoplastic elastomers amapangidwa ndi butadiene ndi isoprene copolymerization, ndipo monga crosslinking monoma, styrene ntchito kusintha PVC, polypropylene, ndi unsaturated poliyesitala.
Syrene imagwiritsidwa ntchito ngati monomer yolimba popanga emulsion ya styrene acrylic ndi zomatira zosungunulira zosungunulira. Emulsion zomatira ndi utoto zitha kukonzedwa ndi copolymerization ndi vinilu acetate ndi akiliriki ester. Styrene ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri pazasayansi, zomwe zimagwiritsidwa ntchito muzinthu zosiyanasiyana zosinthidwa komanso zophatikizika.
Kuphatikiza apo, pang'ono styrene amagwiritsidwanso ntchito ngati mafuta onunkhira ndi zina zapakati. Ndi chloromethylation wa styrene, cinnamyl kolorayidi ntchito ngati wapakatikati kwa sanali anesthetic analgesic mphamvu kutsimikiza ululu, ndi styrene amagwiritsidwanso ntchito ngati antitussive, expectorant ndi anticholinergic mankhwala oyambirira m`mimba Kusintha. Itha kugwiritsidwa ntchito popanga utoto wa anthraquinones, emulsifiers mankhwala ophera tizilombo, ndi ma styrene phosphonic acid ore kuvala wopangira ndi zowunikira zamkuwa.
