Ethanol yog ib yam tshuaj uas siv tau ntau yam thiab siv tau dav dav uas ua lub luag haujlwm tseem ceeb hauv ntau yam lag luam vim nws cov qib kev ntshiab sib txawv. Cov kev ntshiab feem ntau hauv kev ua lag luam yog 99%, 96%, thiab 95%, thiab txhua qhov kev ntshiab muaj kev siv sib txawv hauv ntau yam lag luam. Kev nkag siab txog qhov tseem ceeb ntawm cov kev ntshiab no tuaj yeem pab cov tuam txhab xaiv cov ethanol zoo rau lawv cov ntawv thov tshwj xeeb.
99% ethanol ntshiab feem ntau suav hais tias yog tus qauv kub rau cov lag luam uas xav tau cov tshuaj yaj zoo, xws li cov tshuaj thiab cov chaw kuaj mob. Nws qhov kev ntshiab tshwj xeeb ua kom nws tuaj yeem yaj ntau yam tshuaj yam tsis muaj cov khoom tsis huv uas yuav cuam tshuam rau cov txiaj ntsig. Hauv kev lag luam tshuaj, piv txwv li, 99% ethanol yog qhov tseem ceeb rau kev rho tawm thiab kev ntxuav cov khoom xyaw nquag kom ntseeg tau tias cov tshuaj ua haujlwm tau zoo thiab muaj kev nyab xeeb.
Ntawm qhov tod tes, ethanol nrog qhov huv ntawm 96% feem ntau siv rau hauv kev tsim khoom noj thiab dej haus, nrog rau hauv kev lag luam tshuaj pleev ib ce. Qib kev huv no sib npaug ntawm qhov ua tau zoo thiab kev nyab xeeb, ua rau nws tsim nyog rau kev noj lossis siv rau ntawm daim tawv nqaij. Hauv kev lag luam khoom noj, 96% ethanol feem ntau siv ua cov tshuaj tiv thaiv thiab cov tshuaj tsw qab, thaum hauv kev lag luam tshuaj pleev ib ce, nws yog siv ua cov kuab tshuaj rau ntau yam khoom xyaw.
Thaum kawg, ethanol ntawm 95% purity feem ntau siv rau hauv kev siv hauv kev lag luam xws li kev ntxuav thiab tua kab mob. Nws qhov purity qis dua me ntsis ua rau nws pheej yig dua thaum tseem muab kev ua haujlwm txaus rau cov haujlwm uas tsis xav tau qhov purity siab tshaj plaws. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov chaw tsim khoom uas xav kom lawv cov txheej txheem tsim khoom huv si yam tsis muaj nqi ntau dhau.
Hauv kev xaus, cov qib kev ntshiab sib txawv ntawm ethanol (99%, 96%, thiab 95%) ua lub luag haujlwm tseem ceeb hauv kev ua kom tau raws li cov kev xav tau sib txawv ntawm ntau yam lag luam. Los ntawm kev nkag siab txog cov ntawv thov tshwj xeeb thiab cov txiaj ntsig ntawm txhua qib kev ntshiab, cov tuam txhab tuaj yeem txiav txim siab tau zoo los txhim kho kev ua haujlwm zoo thiab cov khoom zoo.
