Propylene Oxideyog ib hom ntawm cov khoom tseem ceeb organic cov ntaub ntawv raw thiab nruab nrab. Nws yog tsuas yog siv nyob rau hauv cov synthesis ntawm polyether Polyols, polyester polyols, polyterthane, polyterthans, polytertane, thiab yog ib qho tseem ceeb ntawm kev ua haujlwm ntawm kev ua haujlwm ntawm polyurethane. Propylene oxide kuj tseem siv tau ua cov khoom siv raw rau ntau cov surfactants, tshuaj, kev ua liaj ua teb tshuaj, thiab yog ib qho ntawm cov ntaub ntawv tseem ceeb rau kev lag luam tshuaj lom neeg.

Propylene oxide yog tsim los ntawm oxidation ntawm propylene nrog cov catalyst. Cov khoom lag luam nyoos yog cov khoom siv sib xyaw nrog cov huab cua compressed thiab tom qab ntawd dhau los ntawm ib tug reactor uas muaj catalyst. Cov tshuaj tiv thaiv kub feem ntau yog 200-300 deg c, thiab lub siab yog li 1000 kpa. Cov tshuaj tiv thaiv yog qhov sib xyaw muaj cov epylene oxide, carbon dioxide, carbon monoxide, dej thiab lwm yam sib txuas. Lub catalyst siv nyob rau hauv cov tshuaj tiv thaiv no yog ib qho kev hloov tsheb hlau oxide, thiab lwm yam ntawm cov roj pleev cov roj pleev kom zoo, tab sis cov haujlwm tsawg. Tsis tas li ntawd, cov catalyst nws tus kheej yuav ua tsis tau thaum lub sij hawm cov tshuaj tiv thaiv, yog li nws yuav tsum tau tsim lossis hloov tsis tu ncua.

Kev sib cais thiab kev ua kom huv ntawm cov tshuaj pleev kom loj oxide oxide oxide oxide oxide los ntawm cov tshuaj tiv thaiv kab sib xyaw yog cov kauj ruam npaj tau npaj. Lub txheej txheem sib cais feem ntau suav nrog ntxuav cov dej ntxuav, distillation thiab lwm cov kauj ruam. Ua ntej, cov tshuaj tiv thaiv sib xyaw yog ntxuav nrog dej kom tshem cov roj npau npau xws li siv cov tshuaj pleev cov roj carylene thiab carbon monoxide. Tom qab ntawd, qhov sib tov yog distilled cais cov propylene oxide los ntawm lwm lub siab-boiling Cheebtsam. Txhawm rau tau txais cov kev ua kom siab-huv cov epylene oxide, ntxiv cov kauj ruam ntxiv xws li kev kos duab lossis rho tawm tuaj yeem xav tau.

Feem ntau, kev npaj ntawm propylene oxide yog cov txheej txheem nyuaj, uas yuav tsum tau ntau kauj ruam thiab kev siv zog ntau. Yog li ntawd, txhawm rau txo tus nqi thiab ib puag ncig cuam tshuam ntawm cov txheej txheem no, nws yog qhov tsim nyog los txuas ntxiv txhim kho thev naus laus zis thiab cov cuab yeej cuab tam ntawm cov txheej txheem. Tam sim no, kev tshawb fawb ntawm cov txheej txheem tshiab rau kev siv oxidant, thiab cov kev sib cais tshiab rau kev txhim kho cov txiaj ntsig thiab kev ua kom dawb huv ntawm cov tshuaj pleev thiab ua kom zoo nkauj txo cov nqi ntau lawm.
