Isopropyl cawv, tseem hu ua isopropanol lossis rubbing cawv, yog ib hom tshuaj ntxuav tsev thiab cov kuab tshuaj.Nws tus nqi siab feem ntau yog ib qho puzzle rau ntau tus neeg.Hauv tsab xov xwm no, peb yuav tshawb xyuas cov laj thawj vim li cas isopropyl cawv thiaj li kim.

1. Synthesis thiab ntau lawm txheej txheem

Isopropyl cawv feem ntau yog tsim los ntawm propylene, uas yog cov khoom lag luam ntawm cov roj crude distillation.Cov txheej txheem synthesis suav nrog ntau cov kauj ruam, suav nrog cov tshuaj tiv thaiv catalytic, purification, sib cais, thiab lwm yam haujlwm.Cov txheej txheem ntau lawm yog complex thiab yuav tsum tau siv technology siab, ua rau cov nqi ntau lawm.

Tsis tas li ntawd, cov khoom siv raw propylene tsis tsuas yog kim, tab sis kuj muaj kev xav tau siab hauv kev ua lag luam.Qhov no kuj nce tus nqi ntawm isopropyl cawv ntau lawm.

2. Kev lag luam xav tau thiab khoom siv

Isopropyl cawv muaj ntau yam kev siv, suav nrog kev tu tsev, kev kho mob, luam ntawv, txheej, thiab lwm yam lag luam.Yog li ntawd, qhov kev thov rau isopropyl cawv yog qhov siab hauv khw.Txawm li cas los xij, vim muaj peev xwm tsim tau tsawg ntawm cov tuam txhab thiab cov txheej txheem tsim khoom nyuaj, cov khoom siv ntawm isopropyl cawv tsis tuaj yeem ua tau raws li kev xav tau ntawm kev lag luam txhua lub sijhawm.Qhov no ua rau muaj kev cuam tshuam tsis zoo thiab ua rau tus nqi nce.

3. Cov nqi thauj khoom siab

Isopropyl cawv muaj qhov ntom ntom ntom thiab ntim siab thiab ntim, uas txhais tau tias cov nqi thauj mus los yog siab.Cov nqi thauj khoom thiab cov nqi thauj khoom yuav ntxiv rau tus nqi kawg ntawm cov khoom.Yog tias cov nqi tsheb thauj mus los siab dhau lawm, lawv yuav cuam tshuam ncaj qha rau tus nqi ntawm isopropyl cawv.

4. Tsoom fwv cov cai thiab cov se

Qee lub tebchaws tau siv cov se siab ntawm isopropyl cawv los tswj nws kev siv thiab muag.Cov se no yuav nce tus nqi ntawm isopropyl cawv.Tsis tas li ntawd, qee lub tebchaws muaj cov kev cai nruj heev ntawm kev tsim thiab muag ntawm isopropyl cawv kom muaj kev noj qab haus huv rau pej xeem thiab kev tiv thaiv ib puag ncig.Qhov no tseem ua rau cov nqi tsim khoom lag luam thiab nce tus nqi ntawm isopropyl cawv.

5. Hom nqi thiab kev lag luam tawm tswv yim

Qee lub tuam txhab siv cov tswv yim lag luam siab kawg los txhawb lawv cov khoom lag luam hauv kev ua lag luam.Lawv tuaj yeem nce tus nqi ntawm isopropyl cawv los txhim kho cov nqi lag luam thiab kev lag luam kev sib tw.Tsis tas li ntawd, qee lub tuam txhab kuj tseem siv cov khoom lag luam siab kom nyiam cov neeg siv khoom nyiam thiab txhim kho kev lag luam.Lub tswv yim kev lag luam no tseem yuav nce tus nqi ntawm isopropyl cawv.

Hauv cov ntsiab lus, tus nqi siab ntawm isopropyl cawv yog vim muaj ntau yam xws li cov nqi tsim khoom, kev xav tau ntawm kev lag luam thiab cov khoom siv, cov nqi tsheb thauj mus los, tsoomfwv cov cai thiab cov se, nrog rau cov nqi lag luam thiab cov tswv yim lag luam.Txhawm rau txo tus nqi ntawm isopropyl cawv, cov lag luam yuav tsum tau ua kom zoo dua qub thiab txo cov nqi tsim khoom thaum ntxiv dag zog rau kev tshawb fawb kev lag luam thiab kev xav tau kev txheeb xyuas kom tau raws li kev xav tau ntawm kev lag luam.Tsis tas li ntawd, tsoomfwv yuav tsum tau muab kev txhawb nqa rau cov lag luam hauv kev txo se thiab kev hloov pauv kev lag luam los pab cov lag luam txo cov nqi tsim khoom thiab txhim kho kev lag luam kev sib tw.
