Daim teb thov ntawm methanol
Thaj tsam ua haujlwm loj ntawm methanol yog cov khoom lag luam ntawm formaldehyde. Formaldehyde tuaj yeem siv los ua cov nplaum, feem ntau yog siv hauv kev lag luam ntoo ua, thiab qhov thib ob yog tus neeg sawv cev rau kev kho mob rau kev sib xyaw moulding, xim tsev, textiles thiab ntawv.
Kev siv lwm cov tshuaj hnyav nyob hauv kev tsim cov kua qaub (Acetic acid). Acetic acid noj tso nyiaj rau kwv yees li 7% ntawm kev xav tau methanol thoob ntiaj teb, thiab tuaj yeem tsim cov ntaub yas vinyl, acetate thiab acetate. Cov kev xav tau muaj feem cuam tshuam nrog cov kev xav siv rau kev lo, nplaum thiab ntaub.
Methanol tuaj yeem siv los ua cov tshuaj methyl, uas tuaj yeem siv los tsim cov kua qaub, cov qauv thiab lwm yam khoom siv tshuaj zoo, ntxiv rau tshuaj tua kab, fungicides, fumigants, tus neeg sawv cev rau kev haus luam yeeb thiab cov tshuaj ntxiv rau roj av.
Methanol kuj tseem siv tau los ua cov methylamine. Methylamine yog qhov tseem ceeb fatty amine. Nws yog cov khoom siv tshuaj lom neeg ua kom zoo uas tuaj yeem sib cais rau hauv monomethylamine, dimethylamine thiab trimethylamine los ntawm ua kua nitrogen thiab methanol.
Nws tuaj yeem ua ke rau hauv dimethyl carbonate, uas yog ib puag ncig cov khoom siv hauv tshuaj, kev ua liaj ua teb thiab kev lag luam tshwj xeeb.
Nws tuaj yeem muab tso ua ke rau hauv ethylene glycol thiab yog ib qho ntawm cov nruab nrab ntawm petrochemical cov ntaub ntawv. Nws tuaj yeem raug siv los tsim polyester thiab tshuaj tua kab mob.
Yuav siv tau los ua cov txhawb kev loj hlob. Nws tuaj yeem nce cov qoob loo ntawm cov qoob loo, khaws cov nplooj nplooj tshiab thiab muaj zog, vam meej, thiab yuav tsis qhuav hauv lub caij ntuj sov. Nws tuaj yeem txo cov dej kom tsis muaj dej thiab zoo rau kev loj hlob ntawm cov qoob loo qhuav.
Lub cev methanol protein tuaj yeem ua ke los ntawm methanol fermentation. Cov methanol protein ua los ntawm microbial fermentation yog hu ua ob tiam ib zaug ntawm tes protein. Piv nrog cov protein ntuj tsim, cov zaub mov muaj txiaj ntsig zoo dua, cov ntsiab lus ntawm cov zaub mov nyoos yog muaj ntau dua li ntawm cov ntses pluas mov thiab taum pauv, thiab nws muaj cov nplua nuj amino acids, cov zaub mov thiab vitamins, nws tuaj yeem hloov cov ntsesmeme, kua zaub, pob txha pob txha, nqaij thiab skim mis hmoov.

Methanol yog siv los ua tus neeg tu cev thiab tu cev. MOS qib yog siv rau cov khoom txiav tawm, nruab nrab thiab loj qhov sib xyaw ua ke, thiab qib BV-III feem ntau yog siv rau VLSI txheej txheem thev naus laus zis.
Siv raws li kev xav tshuaj lub cev, xws li cov kuab tshuaj, methylation reagent, chromatographic reagent. Kuj tseem siv hauv synthesis organic.
Methanol feem ntau yog cov kuab tshuaj zoo dua li nyob li ethanol thiab tuaj yeem yaj ntau cov ua kua ntsev. Nws kuj tseem tuaj yeem xyaw nrog roj av hluav taws xob li lwm txoj roj. Txij li xyoo 1980, methanol tau siv los tsim cov roj av octane naj npawb ntxiv rau ntxiv xws li methyl tert-butyl ether, methanol roj av, methanol roj, thiab methanol protein, uas tau txhawb kev txhim kho methanol ntau lawm thiab kev ua lag luam xav tau.
Methanol tsis yog tsuas yog cov khoom siv tshuaj tseem ceeb, tab sis kuj yog lub zog zoo tshaj plaws thiab muaj roj tsheb. Methanol yog hnov mob nrog isobutylene los muab MTBE (methyl tert-butyl ether), uas yog lub siab-octane unleaded roj av ntxiv thiab tseem tuaj yeem siv ua cov kuab tshuaj. Ntxiv rau, olefins thiab propylene tuaj yeem tsim tawm los daws cov kev tsis txaus ntawm cov khoom siv.
Methanol tuaj yeem siv los ua cov dimethyl ether. Ntxiv rau nws cov kev siv ntau yam hauv cov tshuaj txhua hnub, tshuaj, tshuaj tua kab, dyes, txheej txheej, thiab lwm yam, nws kuj muaj kev ntxuav yooj yim, cetane tus lej ntau, ua haujlwm zoo dynamic thiab muaj kuab paug tsawg. Yooj yim rau cov khoom zom ua kua, yooj yim khaws thiab lwm yam khoom siv roj. Cov roj ua kua roj tshiab uas npaj los ntawm kev sib tov nrog cov tshuaj methanol thiab dimethyl ether hauv qhov ntsuas piv yog hu ua cawv cawv ether roj. Nws cov kev sib txuas ntau dua thiab kev siv hluav taws xob ntau yog siab dua cov roj liquefied.
