Propylene OxidePuas yog siv cov khoom siv tshuaj lom neeg cov khoom siv tshuaj tsw qab, uas yog siv los ntawm polyether Polyols, thiab lwm yam. Yog li no, lo lus teb rau lo lus nug seb puas epylene oxide yog cov khoom siv hluavtaws yog tau.

Ua ntej tshaj plaws, cia saib ntawm qhov chaw ntawm propylene oxide. Propylene oxide yog hom ntawm cov khoom siv tshuaj lom neeg muaj txiaj ntsig zoo los ntawm propylene. Propylene yog hom ntawm ovefined los ntawm cracking roj av, thiab nws cov qauv molecular muaj tsuas yog cov carbon thiab hydrogen. Yog li no, pr Propylene oxide synthesized los ntawm Propylene kuj yog hom organic sib xyaw ua ke ntawm cov roj carbon thiab hydrogen.

Thib ob, peb tseem tuaj yeem txheeb xyuas cov txheej txheem hluavtaws ntawm cov tshuaj pleev kom ua kom zoo. Cov txheej txheem hluavtaws ntawm propylene outral feem ntau siv ntau catalysts los ua kom cov oxidation ntawm propylene hauv qab kub thiab siab cov xwm txheej. Ntawm lawv, feem ntau siv catalyst yog nyiaj. Nyob rau hauv cov txheej txheem ntawm oxidation cov tshuaj tiv thaiv, propylene thiab oxygen nyob rau saum huab cua yog catalenyzed los ntawm cov nyiaj los tsim cov olelene oxide. Tsis tas li ntawd, lwm cov catalysts xws li titanium dioxide thiab tungsten oxide kuj feem ntau siv rau cov synthesis ntawm cov epylene oxide.

Thaum kawg, peb kuj tuaj yeem txheeb xyuas daim ntawv thov propylene oxide. Propylene oxide feem ntau yog siv nyob rau hauv kev tsim cov polyether Polyols, polyeth Polyols rau kev tu thiab ntxuav. Yog li, daim ntawv thov ntawm propylene oxide yog qhov dav heev.

Raws li kev txheeb xyuas saum toj no, peb tuaj yeem kos ib qho xaus uas propylene oxide tau muab los ntawm propylene los ntawm oxidation cov tshuaj tiv thaiv nrog ntau catalysts nrog ntau yam tshuaj tua kab. Nws cov khoom siv, cov txheej txheem hluavtaws thiab daim ntawv thov muaj feem xyuam nrog tib neeg lub neej thiab cov haujlwm tsim khoom.
