Njirimara kemịkalụ:

Styrene bụ ihe mejupụtara kemịkalụ organic nke nwere usoro kemịkalụ C8H8 na usoro nhazi CH2 = CHC6H5, nke a makwaara dị ka styrol, vinylbenzene, phenylethene, phenylethylene, styrene, styreen na ndị ọzọ. Ihe mejupụtara kemịkal ya bụ mgbanaka benzene nke e jikọtara na otu vinyl. Na okpomọkụ ụlọ na nrụgide, styrene bụ mmiri mmiri doro anya, nke na-enweghị agba. Styrene bụ monomer dị mkpa nke roba sịntetik, adhesives na plastik, dị ka mpempe akwụkwọ styrene.

Ngwa:

Styrene bụ monomer dị mkpa nke roba sịntetik, adhesives na plastik. [3,4,5] A na-eji ya eme ihe maka njikọ nke styrene butadiene roba na polystyrene resin, polyester glass fiber mesikwuru plastik na mkpuchi. A na-eji ya maka ịkwadebe polystyrene, resin mgbanwe ion, na polystyrene foam. A na-ejikwa ya maka copolymerization na monomers ndị ọzọ iji mepụta plastik injinịa dị iche iche, dị ka copolymerization nke acrylonitrile na butadiene iji mepụta resin ABS, nke a na-ejikarị na ngwa ụlọ na ụlọ ọrụ dị iche iche. Copolymerization na acrylonitrile, nwetara SAN bụ resin nwere ujo na-eguzogide na agba na-egbuke egbuke. SBS nke copolymerization na butadiene mepụtara bụ roba thermoplastic, nke a na-ejikarị eme ihe dị ka polyvinyl chloride na acrylic modifier. A na-eme SBS na SIS thermoplastic elastomers na butadiene na isoprene copolymerization, na dị ka monomer na-agafe agafe, a na-eji styrene mee ihe na mgbanwe nke PVC, polypropylene, na polyester na-adịghị mma.
A na-eji Syrene dị ka monomer siri ike maka mmepụta nke emulsion styrene acrylic na nrapado mmetụta mgbaze. Emulsion nrapado na agba nwere ike kwadebere site copolymerization na vinyl acetate na acrylic ester. Styrene bụ otu n'ime vinyl monomers ndị a na-ejikarị eme ihe na ngalaba sayensị, nke a na-eji n'ụdị dị iche iche gbanwetụrụ na ihe mejupụtara.[6].
Tụkwasị na nke ahụ, a na-ejikwa obere styrene dị ka ihe na-esi ísì ụtọ na ndị ọzọ dị n'etiti. Site na chloromethylation nke styrene, a na-eji cinnamyl chloride mee ihe dị n'etiti maka mkpebi mgbu na-adịghị anestetiiki analgesic siri ike, a na-ejikwa styrene dị ka ọgwụ antitussive, expectorant na anticholinergic mbụ na afọ na-agbanwe. Enwere ike iji ya na-emepụta ihe ndị na-esiji ihe anthraquinones, emulsifiers pesticide, na styrene phosphonic acid ore na ihe mgbakwasa ọla kọpa.
