Propylene oxide yog hom ntawm cov ntaub ntawv tshuaj raw thiab nruab nrab, uas yog siv dav hauv kev tsim cov polyols, polyester, cov tshuab polyester, surfactanes, surfactants thiab lwm yam kev lag luam. Tam sim no, kev tsim cov epylene oxide feem ntau muab faib ua peb yam: tshuaj lom neeg, enzyme catalytic catalesis thiab bermentation fermentation. Peb txoj hauv kev muaj lawv tus cwj pwm thiab daim ntawv thov tau. Hauv daim ntawv no, peb yuav txheeb xyuas cov teeb meem tam sim no thiab kev txhim kho ntawm cov thev naus laus zis roj hmab, tshwj xeeb tshaj yog cov yam ntxwv ntawm peb txoj kev ntau lawm, thiab sib piv qhov teeb meem hauv Suav teb.

Ua ntej tshaj plaws, cov tshuaj lom neeg synthesis oxide yog ib tus qauv ib txwm muaj, uas muaj qhov zoo ntawm cov thev naus laus zis, cov txheej txheem yooj yim thiab tus nqi qis. Nws tau muaj keeb kwm ntev thiab nthuav dav cov kev cia siab. Ib qho ntxiv, qauv tshuajntsw synthesis tseem tuaj yeem siv rau kev tsim cov khoom siv raw khoom tseem ceeb thiab cov nruab nrab, xws li oxes oxide, butylene oxide thiab styrene oxide thiab styrene oxide. Txawm li cas los xij, hom no tseem muaj qee qhov tsis zoo. Piv txwv li, kev siv tshuab hluav taws xob hauv cov txheej txheem feem ntau yog qhov tsis sib xws thiab muaj kev nyuaj, uas yuav ua rau kev puas tsuaj rau cov khoom siv thiab ib puag ncig pa paug. Tsis tas li ntawd, cov txheej txheem tsim cov txheej txheem yuav tsum tau haus ntau lub zog thiab dej kev pab, uas yuav ua rau cov nqi ntau lawm. Yog li ntawd, hom no tsis haum rau ntau-teev ntau lawm hauv Suav teb.

Qhov thib ob, enzyme catalytic cov qauv hluavtaws yog txoj kev tshiab tsim nyob rau xyoo tas los no. Cov qauv no siv cov enzymes ua catalysts los hloov propylene rau hauv cov tshuaj yaig rau cov oxes oxide. Hom no muaj ntau yam zoo. Piv txwv li, cov qauv no tau hloov dua siab tshiab thiab xaiv cov kev xaiv ntawm enzyme catalyst; Nws muaj cov pa phem tsis muaj kuab lom thiab siv hluav taws xob me; Nws tuaj yeem nqa tawm hauv qab cov kev tshwm sim me me; Nws kuj tseem tuaj yeem tsim lwm cov ntaub ntawv nyoos thiab cuam tshuam los ntawm kev hloov catalysts. Tsis tas li ntawd, cov qauv no siv cov kev sib txuas lus tsis zoo uas yog cov tshuaj tiv thaiv kev ua haujlwm lossis cov mob hnyav rau kev cuam tshuam rau kev ua haujlwm ib puag ncig. Txawm hais tias hom no muaj ntau yam zoo, tseem muaj qee qhov teeb meem uas yuav tsum tau daws. Piv txwv li, tus nqi ntawm enzyme catalyst yog qhov siab, uas yuav ua rau cov nqi ntau lawm; Lub enzyme catalyst yog ib qho yooj yim kom ua tsis tiav lossis ua tsis tau zoo hauv cov txheej txheem tshuaj tiv thaiv; Tsis tas li ntawd, hom no tseem nyob hauv chav kuaj mob nyob rau theem tam sim no. Yog li ntawd, cov qauv no xav tau kev tshawb fawb ntau dua thiab tsim kho cov teeb meem no ua ntej nws tuaj yeem siv rau kev lag luam khoom.

Thaum kawg, tus qauv fermological fermentation txujci kuj yog txoj kev tshiab tsim nyob rau xyoo tas los no. Cov qauv no siv cov kab mob me li catalysts los hloov propylene rau hauv cov tshuaj pleev kom ua rau epylene oxide. Hom no muaj ntau yam zoo. Piv txwv li, cov qauv no tuaj yeem siv cov peev txheej txuas ntxiv xws li cov ntaub pua chaw ua liaj ua teb yog cov khoom siv raw; Nws muaj cov pa phem tsis muaj kuab lom thiab siv hluav taws xob me; Nws tuaj yeem nqa tawm hauv qab cov kev tshwm sim me me; Nws kuj tseem tuaj yeem tsim lwm cov ntaub ntawv nyoos thiab cov nruab nrab ntawm cov microorganisms. Tsis tas li ntawd, cov qauv no siv cov kev sib txuas lus tsis zoo uas yog cov tshuaj tiv thaiv kev ua haujlwm lossis cov mob hnyav rau kev cuam tshuam rau kev ua haujlwm ib puag ncig. Txawm hais tias hom no muaj ntau yam zoo, tseem muaj qee qhov teeb meem uas yuav tsum tau daws. Piv txwv li, cov kab mob me me yuav tsum tau xaiv thiab tshuaj ntsuam; Qhov ntsuas hloov dua siab tshiab thiab xaiv cov microorganism catalyst tseem tsawg; Nws yuav tsum tau kawm ntxiv yuav ua li cas tswj hwm cov txheej txheem tsis ua kom ntseeg tau tias ua haujlwm ruaj khov thiab ntau lawm ntau lawm; Hom no tseem xav tau kev tshawb fawb ntxiv thiab kev txhim kho ua ntej nws tuaj yeem siv rau kev lag luam theem ntau lawm.

Hauv kev xaus, txawm hais tias tshuaj synthesis txoj kev tau ntev keeb kwm thiab kev siv teeb meem xws li kev ua qias tuaj thiab kev siv hluav taws xob ntau. Enzyme catalytic txoj kev synthesis yog txoj kev tshiab nrog kev tshawb fawb tsawg dua thiab kev tsim kho me ntsis ua ntej lawv tuaj yeem siv rau kev lag luam theem ntau lawm. Tsis tas li ntawd, txhawm rau kom ua tiav cov roj loj loj ntawm cov olylene oxide hauv cov hauv ntej, peb tuaj yeem txhawb nqa cov kev lag luam R & D tau zoo dua qub ua ntej kev tsim khoom loj ua ntej kev tsim khoom loj yog pom tau.
