IsoPropanolyog cov kua tsis muaj kob, cov kua dej uas tau siv dav hauv ntau yam kev lag luam xws li cov kuab tshuaj, rub, cov nplaum, thiab lwm tus. Ib qho ntawm thawj txoj hauv kev los tsim isopropanol yog los ntawm hydrogenation ntawm acetone. Hauv tsab xov xwm no, peb yuav delve ntxaum rau hauv cov txheej txheem no.

Thawj kauj ruam hauv kev hloov dua siab tshiab ntawm acetone rau isopropanol yog los ntawm hydrogenation. Qhov no ua tiav los ntawm kev rov qab ua acetone nrog hydrogen roj nyob rau hauv muaj ib tug catalyst. Cov tshuaj tiv thaiv cov tshuaj tiv thaiv rau tus txheej txheem no yog:

2C3C (O) CH3 + 3H2 ->>> 2CH3CHCHCH3

Lub catalyst siv nyob rau hauv qhov kev tawm tsam no yog feem ntau yog cov nove hlau xws li palladium lossis platinum. Qhov kom zoo dua ntawm kev siv cov catalyst yog tias nws txo qis lub zog yuav tsum muaj rau cov tshuaj tiv thaiv kom ua, nce nws txoj kev ua tau zoo.

Tom qab hydrogenation kauj ruam, cov khoom lag luam uas yog sib xyaw ntawm isopropanol thiab dej. Cov kauj ruam tom ntej nyob rau hauv tus txheej txheem cuam tshuam nrog ob feem. Qhov no feem ntau ua tiav siv txoj kev distillation. Lub ntsiab lus npau npau ntawm cov dej thiab isopropanol yog qhov sib ze sib luag, tab sis los ntawm cov fractional distillations, lawv tuaj yeem sib cais.

Thaum cov dej tau muab tshem tawm, cov khoom lag luam uas yog isopropanol ntshiab. Txawm li cas los xij, ua ntej nws tuaj yeem siv rau hauv ntau yam kev siv, nws yuav tsum tau mus ua kom muaj kev lim dej ntau ntxiv xws li lub cev qhuav dej xws li lub cev qhuav dej los yog hydrogenation kom tshem tawm cov khoom tsis muaj zog.

Cov txheej txheem tshaj plaws los tsim isopropanol los ntawm acetone cuam tshuam nrog peb qib tseem ceeb: hydrogenation, sib cais, thiab kev sib cais, thiab kev sib cais, thiab kev sib cais, thiab ua kom huv. Txhua kauj ruam ua si lub luag haujlwm tseem ceeb hauv kev ua kom pom tseeb tias cov khoom kawg tau raws li cov qauv kev coj dawb huv thiab cov qauv zoo.

Tam sim no koj muaj kev nkag siab zoo dua ntawm isopropanol yog tsim los ntawm acetone, koj tuaj yeem txaus siab rau cov txheej txheem hloov siab tshiab. Cov txheej txheem yuav tsum muaj kev sib xyaw ua ke ntawm lub cev thiab tshuaj lom neeg muaj kev cuam tshuam rau kev tswj hwm kom tau txiaj ntsig isopropanol. Ib qho ntxiv, kev siv cov catalysts, xws li palladium lossis platinum, plays ib qho tseem ceeb tshaj plaws hauv kev txhim kho kev ua haujlwm ntawm cov tshuaj tiv thaiv.
