Cov ncauj lus kom ntxaws tshuaj ntawm lub boiling taw tes ntawm methanol
Methanol yog ib qho tseem ceeb tshaj plaws cov ntaub ntawv hauv kev lag luam tshuaj, thiab yog siv dav raws li roj, kuab tshuaj thiab tshuaj lom neeg. Hauv daim ntawv no, peb yuav txheeb xyuas qhov teeb meem ntawm "methanol boil point", thiab sib tham txog qhov tob ntawm methanol, qhov tseem ceeb hauv kev siv cov ntawv thov.
Lub cev ntawm lub cev ntawm methanol
Methanol, tseem hu ua ntoo cawv lossis ntoo dab, tshuaj siv tshuaj rau Chioh, yog qhov yooj yim haus cawv sib txawv. Raws li cov xim tsis muaj kob, kua roj, methanol yog qhov nrov heev thiab tsis tshua muaj txiaj ntsig. Nws lub point boiling yog qhov tseem ceeb rau kev nkag siab txog cov khoom ntawm methanol. Ntawm atighpheric siab, methanol muaj lub boiling taw tes ntawm 64.7 ° C (14.5 ° F), uas ua rau nws raug rau kev hloov pauv ntawm chav sov. Yog li ntawd, thaum tuav thiab khaws cov methanol, nws yog ib qho tseem ceeb uas yuav tau txiav txim siab nws cov kev tsis sib xws thiab cov nplaim taws thiab coj kev ntsuas kev nyab xeeb txog kev nyab xeeb.
Yam cuam tshuam rau lub boiling taw tes ntawm methanol
Muaj ntau cov ntsiab lus uas yuav tsum tau coj mus rau hauv tus account thaum nkag siab txog qhov teeb meem ntawm "methanol npau taw". Cov qauv molecular ntawm methanol txiav txim nws qhov cub npau npau tsawg. Lub methanol molecule muaj ib pab methyl (ch ₃) thiab cov pab pawg hydroxyl (Oh) thiab muaj ib pawg nyhav me. Vim tias muaj cov pab pawg nruab nrab hauv hydroxyl pab pawg, qhov no nce nws qhov cub npau npau, tab sis nws tseem qis dua li lwm cov dej cawv nrog hnyav dua molecular hnyav.
Sab nraud mob xws li kev hloov pauv hauv siab kuj tseem tuaj yeem cuam tshuam rau cov methanol ntawm methanol. Nyob rau hauv cov kev mob siab qis, lub tswb ntsuas ntawm methanol txo, hos nyob rau hauv cov kev mob siab, nws nce. Yog li ntawd, nws yuav tsim nyog los tswj cov tshuaj methanol evaporation thiab cov txheej txheem hws los ntawm kev kho lub siab ntawm cov txheej txheem sib txawv.
Qhov Tseem Ceeb ntawm Methanol Boiling Taw Taw Rau Hauv Kev Muaj Kev Siv
Lub tswb ntsuas ntawm methanol yog qhov tseem ceeb rau nws daim ntawv thov hauv kev tsim cov tshuaj lom neeg. Piv txwv li, hauv methanol ntau lawm, nws yog qhov tseem ceeb kom tswj tau qhov kev sib cais kom tsim nyog thiab lub siab rau kev sib cais ua tau zoo thiab ua kom huv ntawm methanol. Vim nws lub boiling qis, methanol tuaj yeem evaporated ntawm atmospheric siab siv cov khoom siv cua sov cua sov, uas yog qhov zoo tshaj plaws ntawm kev txuag hluav taws xob.
Methanol lub boiling point kuj tseem ua rau nws cov kuab tshuaj zoo tshaj plaws, tshwj xeeb hauv cov ntawv thov uas yuav tsum tau nrawm nrawm, xws li cov xim av thiab tshuaj ntxuav. Thaum siv, qhov kub thiab qhov chaw ua haujlwm yuav tsum tau tswj kev ua haujlwm kom tiv thaiv kev tsim cov methanol vapor, yog li zam kev phom sij lossis kev noj qab haus huv.

Los ntawm cov kev tsom xam saum toj no, nws tuaj yeem pom tau tias nkag siab tias "npau npau kis methanol" yog qhov tsim nyog siv ntawm methanol hauv kev siv tshuaj. Lub tswb ntsuas ntawm methanol tsis tsuas yog cuam tshuam nws lub cev nqaij daim tawv thiab kev khiav hauj lwm muaj feem xyuam rau nws xaiv thiab siv hauv ntau daim ntawv thov. Qhov kev paub no pab kom ua kom zoo dua kev siv cov txheej txheem, txuag lub zog thiab nce ntau lawm ntau lawm kev ua haujlwm.
