Methanol thiabisopropanolyog ob feem ntau siv cov kuab tshuaj.Thaum lawv qhia qee qhov sib xws, lawv kuj muaj cov khoom sib txawv thiab cov yam ntxwv uas ua rau lawv sib nrug.Hauv tsab xov xwm no, peb yuav delve rau hauv qhov tshwj xeeb ntawm ob cov kuab tshuaj no, piv rau lawv lub cev thiab tshuaj lom neeg, nrog rau lawv cov kev siv thiab kev nyab xeeb profiles.

Cia peb pib nrog methanol, tseem hu ua ntoo cawv.Nws yog cov kua ntshiab, tsis muaj xim uas yog miscible nrog dej.Methanol muaj qhov kub ntawm qhov kub ntawm 65 degrees Celsius, uas ua rau nws tsim nyog siv rau hauv cov ntawv thov kub.Nws muaj qhov ntsuas octane siab, uas txhais tau hais tias nws tuaj yeem siv los ua cov kuab tshuaj thiab cov tshuaj tiv thaiv kabmob hauv cov roj av.

Methanol kuj tseem siv los ua khoom noj hauv kev tsim khoom ntawm lwm cov tshuaj, xws li formaldehyde thiab dimethyl ether.Nws kuj yog ua hauj lwm nyob rau hauv zus tau tej cov biodiesel, ib tug tauj dua tshiab roj qhov chaw.Ntxiv rau nws cov ntawv thov kev lag luam, methanol kuj tseem siv rau hauv kev tsim cov kua roj vanish thiab lacquers.

Tam sim no cia peb tig mus rau isopropanol, tseem hu ua 2-propanol lossis dimethyl ether.Cov kuab tshuaj no tseem meej thiab tsis muaj xim, nrog rau qhov kub kub me ntsis siab dua methanol ntawm 82 degrees Celsius.Isopropanol yog cov miscible heev nrog ob qho tib si dej thiab lipids, ua rau nws cov kuab tshuaj zoo heev rau ntau yam kev siv.Nws yog feem ntau siv los ua tus neeg sawv cev txiav hauv cov xim thinners thiab hauv kev tsim cov hnab looj tes latex.Isopropanol kuj tseem siv rau hauv kev tsim cov nplaum, sealants, thiab lwm yam polymers.

Thaum nws los txog rau kev nyab xeeb, ob qho tib si methanol thiab isopropanol muaj lawv tus kheej kev phom sij.Methanol yog tshuaj lom thiab tuaj yeem ua rau qhov muag tsis pom kev yog tawg ntawm qhov muag lossis noj.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 thiab tsis tshua muaj hluav taws xob ntau dua li methanol thaum sib xyaw nrog huab cua.Txawm li cas los xij, nws tseem yog nplaim taws thiab yuav tsum tau ua tib zoo saib xyuas.

Hauv kev xaus, methanol thiab isopropanol yog ob qho tib si muaj txiaj ntsig muaj cov kuab tshuaj nrog lawv cov khoom tshwj xeeb thiab kev siv.Qhov kev xaiv ntawm lawv yog nyob ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov thiab kev ruaj ntseg profile ntawm txhua qhov hnyav.Methanol muaj qhov kub qis dua thiab tawg ntau dua, thaum isopropanol muaj qhov kub siab dua thiab tsis tshua muaj hluav taws kub tab sis tseem muaj hluav taws kub.Thaum xaiv cov kuab tshuaj, nws yog ib qho tseem ceeb uas yuav tau xav txog nws lub cev lub cev, tshuaj stability, toxicity, thiab flammability profile kom ntseeg tau tias kev nyab xeeb thiab siv tau zoo.
