Propylene oxideyog cov khoom siv tshuaj lom neeg siv dav, uas feem ntau yog siv rau hauv kev tsim cov polyether polyols, polyurethanes, surfactants, thiab lwm yam. Cov propylene oxide siv rau cov synthesis ntawm cov khoom no feem ntau tau los ntawm oxidation ntawm propylene nrog ntau yam catalysts. Yog li ntawd, lo lus teb rau lo lus nug seb puas propylene oxide yog hluavtaws yog muaj.

Ua ntej ntawm tag nrho cov, cia peb saib lub hauv paus ntawm propylene oxide. Propylene oxide yog ib hom tshuaj tseem ceeb raw khoom tau los ntawm propylene. Propylene yog ib hom olefin tau los ntawm cov roj av tawg, thiab nws cov qauv molecular yog tsim los ntawm carbon thiab hydrogen nkaus xwb. Yog li ntawd, propylene oxide synthesized los ntawm propylene kuj yog ib hom organic compound uas tsuas yog carbon thiab hydrogen.

Qhov thib ob, peb tuaj yeem txheeb xyuas cov txheej txheem hluavtaws ntawm propylene oxide. Cov txheej txheem hluavtaws ntawm propylene oxide feem ntau siv ntau yam catalysts los ua cov tshuaj tiv thaiv oxidation ntawm propylene nyob rau hauv qhov kub thiab txias. Ntawm lawv, feem ntau siv catalyst yog nyiaj. Nyob rau hauv tus txheej txheem ntawm oxidation cov tshuaj tiv thaiv, propylene thiab oxygen nyob rau hauv cov huab cua yog catalyzed nyiaj los tsim propylene oxide. Tsis tas li ntawd, lwm cov catalysts xws li titanium dioxide thiab tungsten oxide kuj tau siv rau kev sib txuas ntawm propylene oxide.

Thaum kawg, peb tuaj yeem txheeb xyuas qhov kev thov ntawm propylene oxide. propylene oxide feem ntau yog siv los tsim cov polyether polyols, polyurethanes, surfactants, thiab lwm yam. Cov khoom no tau siv dav hauv lub neej txhua hnub, xws li polyurethane ua npuas ncauj rau rwb thaiv tsev thiab kev poob siab, polyether polyols rau epoxy resins, surfactants rau kev ntxuav thiab ntxuav. Yog li ntawd, daim ntawv thov ntawm propylene oxide yog dav heev.

Raws li kev soj ntsuam saum toj no, peb tuaj yeem kos qhov xaus tias propylene oxide yog cov khoom siv hluavtaws tau los ntawm propylene los ntawm oxidation cov tshuaj tiv thaiv nrog ntau yam catalysts. Nws qhov chaw, txheej txheem hluavtaws thiab daim ntawv thov yog txhua yam cuam tshuam nrog tib neeg lub neej thiab kev ua haujlwm ntau lawm.
