Methanol, tseem hu ua methyl cawv, ntoo cawv, ntoo naphtha, methyl hydrate, lossis ntoo ntsuj plig, yog tshuaj nrog cov mis CH3OH (feem ntau yog MeOH luv). Methanol tau txais lub npe" ntoo cawv" vim tias nws tau tsim ua ib zaug dhau los ua cov khoom tsim los ntawm kev ua kom puas tsuaj ntawm cov ntoo. Niaj hnub no, cov tshuaj methanol tau tsim hauv txheej txheem catalytic ncaj qha los ntawm cov pa roj carbon monoxide, carbon dioxide, thiab hydrogen.

Methanol yog cawv yooj yim tshaj plaws, tsuas yog pab pawg methyl txuas rau pawg hydroxyl. Nws yog lub teeb, tsis hloov pauv, tsis muaj xim, ua kua ua kua nrog cov ntxhiab tsw zoo ib yam li ntawm ethanol (haus cawv). Txawm li cas los xij, tsis zoo li ethanol, methanol yog lom heev thiab tsis haum rau siv. Hauv chav sov, nws yog cov kua ncov qaumteb qabteb, thiab tau siv los ua tshuaj tua kab mob, ua kom hnyav, roj, thiab ua qhov tsis lees paub rau ethanol. Nws kuj tseem siv los tsim cov biodiesel ntawm cov tshuaj tiv thaiv transesterification.

Methanol tau tsim tawm ib txwm nyob rau hauv cov metabolism hauv anaerobic ntawm ntau yam kab mob, thiab feem ntau tshwm sim me me hauv ib puag ncig. Vim li ntawd, huab cua muaj me me ntawm cov tshuaj methanol. Tab sis tsuas yog ob peb hnub, methanol huab cua tau oxidized los ntawm tshav ntuj los tsim cov pa roj carbon dioxide thiab dej.Methanol kuj tseem pom muaj ntau hauv cov hnub qub tsim ua thaj chaw ntawm thaj chaw, thiab tau siv hauv kev tshawb fawb hnub qub los ua cim rau thaj tsam ntawd. Nws tau kuaj pom los ntawm nws cov kab hluav taws xob tso tawm.Methanol hlawv hauv cov pa, suav nrog qhib cua, tsim cov pa roj carbon dioxide thiab dej: 2 CH3OH + 3 O2 → 2 CO2 + 4 H2O

Methanol noj ntau ntau yog metabolized ua ntej rau formaldehyde thiab tom qab ntawd mus rau formic acid [13] lossis tsim cov ntsev, uas yog lom rau hauv lub hauv paus paj hlwb thiab yuav ua rau dig muag, tsis nco qab, thiab tuag. Vim tias cov tshuaj lom no, cov tshuaj methanol nquag siv los ua cov tshuaj tsis haum rau ethanol tsim rau kev lag luam. Qhov ntxiv ntawm methanol no zam kev tsim cov ethanol (feem ntau hu ua&"; cawv tsis raug cai &"; lossis&"; methylated plig &";) los ntawm kev sau se cawv hauv Asmeskas thiab qee lub tebchaws.
