Isopropanolyog ib qho organic compound nrog ntau yam kev siv, nrog rau cov tshuaj tua kab mob, cov kuab tshuaj, thiab cov khoom siv tshuaj lom neeg. Nws muaj ntau yam kev siv hauv kev lag luam thiab lub neej txhua hnub. Txawm li cas los xij, kev nkag siab txog cov txheej txheem tsim khoom ntawm isopropanol yog qhov tseem ceeb rau peb kom nkag siab zoo dua nws cov khoom thiab kev siv. Kab lus no yuav muab cov ncauj lus qhia ntxaws txog kev tsim cov txheej txheem ntawm isopropanol thiab nws cov teeb meem cuam tshuam.

Lub cev tseem ceeb:

1.Synthesis txoj kev ntawm isopropanol

Isopropanol feem ntau yog tsim los ntawm hydration ntawm propylene. Propylene hydration yog txheej txheem ntawm reacting propylene nrog dej los tsim isopropanol nyob rau hauv qhov kev txiav txim ntawm ib tug catalyst. Catalysts ua lub luag haujlwm tseem ceeb hauv cov txheej txheem no, vim tias lawv tuaj yeem ua kom nrawm cov tshuaj tiv thaiv thiab txhim kho cov khoom xaiv. Tam sim no, feem ntau siv catalysts suav nrog sulfuric acid, alkali hlau oxides, thiab ion pauv resins.

2.Qhov chaw ntawm propylene

propylene feem ntau yog los ntawm fossil fuels xws li roj thiab nkev roj. Yog li ntawd, kev tsim cov txheej txheem ntawm isopropanol nyob ntawm qee qhov ntawm fossil fuels. Txawm li cas los xij, nrog kev paub txog kev tiv thaiv ib puag ncig thiab kev txhim kho lub zog tauj dua tshiab, tib neeg tab tom tshawb nrhiav cov txheej txheem tshiab los tsim cov propylene, xws li los ntawm kev siv tshuaj lom neeg los yog cov tshuaj synthesis.

3.Manufacturing txheej txheem ntws

Cov txheej txheem tsim khoom ntawm isopropanol feem ntau suav nrog cov kauj ruam hauv qab no: propylene hydration, catalyst rov qab, cov khoom sib cais, thiab kev ua kom zoo. Propylene hydration tshwm sim ntawm qhov kub thiab txias, thaum lub sij hawm lub catalyst yog ntxiv rau qhov sib tov ntawm propylene thiab dej. Tom qab cov tshuaj tiv thaiv tiav, cov catalyst yuav tsum tau rov qab los txo cov nqi tsim khoom. Cov khoom sib cais thiab kev ua kom zoo yog cov txheej txheem ntawm kev sib cais isopropanol los ntawm cov tshuaj tiv thaiv sib xyaw thiab ua kom zoo kom tau txais cov khoom lag luam siab.

Isopropanol yog ib qho tseem ceeb organic compound nrog ntau yam kev siv. Cov txheej txheem tsim khoom feem ntau suav nrog cov tshuaj tiv thaiv dej ntawm propylene, thiab cov catalyst plays lub luag haujlwm tseem ceeb hauv cov txheej txheem no. Txawm li cas los xij, tseem muaj qee qhov teeb meem nrog rau hom catalyst siv hauv kev tsim cov isopropanol thiab qhov chaw ntawm propylene, xws li kev ua qias tuaj ib puag ncig thiab kev siv peev txheej. Yog li ntawd, peb yuav tsum tau txuas ntxiv tshawb nrhiav cov txheej txheem tsim khoom tshiab thiab thev naus laus zis kom ua tiav ntsuab, ua haujlwm tau zoo, thiab muaj txiaj ntsig zoo ntawm isopropanol.
