Methanol thiabisoPropanolyog ob feem ntau siv cov kuab tshuaj muaj kev muaj zog. Thaum lawv qhia qee yam sib xws, lawv kuj muaj cov khoom sib txawv thiab cov yam ntxwv uas teeb tsa lawv sib nrug. Hauv tsab xov xwm no, peb yuav delve rau hauv cov lus qhia tshwj xeeb ntawm ob cov daws teeb meem no, piv lawv cov khoom siv lub cev thiab tshuaj lom neeg thiab kev nyab xeeb.

Cia peb pib methanol, tseem hu ua ntoo cawv. Nws yog cov kua ntshiab, tsis muaj kob uas tsis meej nrog dej. Methanol muaj qhov cub npau npau tsawg ntawm 65 degrees Celsius, uas ua rau nws haum rau siv nyob rau hauv cov ntawv thov tsawg-. Nws muaj lub siab nyiam octane siab, uas txhais tau tias nws tuaj yeem siv los ua cov kuab tshuaj thiab cov tshuaj tiv thaiv ntawm cov roj hauv roj.

Methanol kuj tseem siv los ua cov pub mis nyob rau hauv kev tsim cov tshuaj, xws li formaldehyde thiab didethyil ether. Nws tseem ua haujlwm hauv kev tsim cov roj biodiesel, cov roj txuas ntxiv dua tshiab. Ntxiv rau nws cov ntawv thov kev lag luam, methanol tseem siv nyob rau hauv kev tsim cov kua roj vanish thiab lacquers.

Tam sim no cia tig peb cov xim rau isopropanol, tseem hu ua 2-propanol lossis dauv etheril ether. Cov kuab tshuaj no tseem meej thiab tsis muaj xim, nrog lub qhov cub npau npau tsawg dua metanol ntawm 82 degrees Celsius. IsoPropanol yog qhov ua tau zoo heev nrog ob qho dej thiab cov lipids, ua rau nws yog cov kuab tshuaj zoo rau ntau cov ntawv thov. Nws yog ib qho siv tau siv raws li tus neeg saib xyuas txiav hauv cov xim looj tes nyias nyias thiab hauv cov hnab looj tes yas. IsoPropanol tseem siv nyob rau hauv kev tsim cov nplaum, cov kab xev, thiab lwm cov polymers.

Thaum nws los txog rau kev nyab xeeb, ob qho methanol thiab isopropanol muaj lawv tus kheej qhov phom sij tshwj xeeb. Methanol yog lom thiab tuaj yeem ua rau dig muag yog tias cuam tshuam hauv lub qhov muag lossis ingested. Nws kuj yog cov nplaim taws heev thiab tawg thaum sib xyaw nrog huab cua. Ntawm qhov tod tes, isopropanol muaj qhov ntsuas hluav taws xob tsawg dua thiab tsis tawg tshaj li methanol thaum sib tov nrog cua. Txawm li cas los xij, nws tseem yog cov nplaim taws thiab yuav tsum ua kom zoo nrog kev saib xyuas.

Hauv kev xaus, methanol thiab isopropanol yog ob qho txiaj ntsig muaj txiaj ntsig zoo ntawm lawv tus kheej cov khoom muaj txiaj ntsig thiab cov ntawv thov. Qhov kev xaiv ntawm lawv nyob ntawm qhov tshwj xeeb uas tau ua ntawm daim ntawv thov thiab cov ntaub ntawv kev nyab xeeb ntawm txhua qhov hnyav. Methanol muaj qhov qis dua npau npau thiab yog ntau tawg, thaum isopropanol muaj qhov cub kub dua thiab tsis tshua muaj neeg tawg. Thaum xaiv cov kuab tshuaj, nws yog ib qho tseem ceeb kom xav txog nws lub cev, tshuaj lom neeg ruaj ntseg, tshuaj ntsuam xyuas cov tshuaj lom los ua kom muaj kev nyab xeeb thiab siv tau zoo.
