styrene e sebelisoang ho polima

Styrene ke mokelikeli o hlakileng oa hydrocarbon o hlahisoang haholo ho tsoa lihlahisoa tsa peterole ka mor'a ts'ebetso ea "fractional distillation" ho ntša li-olefin le aromatics tse hlokahalang bakeng sa lisebelisoa tsa lik'hemik'hale ho hlahisa Styrene.Boholo ba limela tsa lik'hemik'hale tsa petrochemical li tšoana le setšoantšo se ka ho le letona.Ela hloko kholomo e kholo e emeng e bitsoang "fractional distillation column".Mona ke moo likarolo tsa petroleum li futhumatsang mocheso o phahameng hobane e 'ngoe le e' ngoe ea likarolo tse kholo tsa lik'hemik'hale li na le lintlha tse fapaneng tsa ho belisa kahoo li li arola ka mokhoa o nepahetseng haholo.

Styrene ke se tsejoang ka har'a khemistri e le monoma.Karabelo ea li-monomers tse etsang "ketane" le bokhoni ba ho hokahana le limolek'hule tse ling li bohlokoa tlhahisong ea Polystyrene.Limolek'hule tsa styrene li boetse li na le sehlopha sa vinyl (ethenyl) se arolelanang lielektrone ka karabelo e tsejoang e le covalent bonding, sena se e lumella hore e etsoe ka polasetiki.Khafetsa, Styrene e hlahisoa ka mehato e 'meli.Ntlha ea pele, alkylation ea benzene (e leng unsaturated hydrocarbon) e nang le ethylene ho hlahisa ethylbenzene.Aluminium chloride catalyzed alkylation e ntse e sebelisoa limela tse ngata tsa EB (ethylbenzene) lefatšeng ka bophara.Ha seo se se se entsoe, EB e kenngoa ka mokhoa o nepahetseng haholo oa dehydrogenation ka ho fetisa EB le mouoane holim'a sesebelisoa se kang iron oxide, aluminium chloride, kapa morao tjena, mokhoa o tsitsitseng oa bethe ea zeolite ho fumana mofuta o hloekileng haholo oa Styrene.Hoo e ka bang ethylbenzene eohle e hlahisoang lefatšeng ka bophara e sebelisetsoa ho etsa li-styrene.Khatelo-pele ea morao-rao tlhahisong ea Styrene e ekelitse mekhoa eo Styrene e ka hlahisoang ka eona.Mokhoa o mong ka ho khetheha o sebelisa Toluene le Methanol sebakeng sa EB.Ho khona ho sebelisa li-feedstocks tse fapaneng ho etsa hore Styrene e be mohloli oa tlholisano oa theko e tlase.
