Methanol (tseem hu ua methyl cawv thiab cawv ntoo) yog cov xim tsis muaj xim, tsis muaj kuab lom, thiab nplaim taws nrog cov tshuaj formula CH3OH.
Methanol feem ntau yog siv los ua cov tshuaj tua kab mob, cov kuab tshuaj, roj, thiab ua cov denaturant rau ethyl cawv. Nws kuj yog siv los ua biodiesel ntawm transesterification cov tshuaj tiv thaiv.
Characterization ntawm Methanol
Methanol (Methyl cawv)yog cov cawv uas yooj yim tshaj plaws, uas ua tiav nrog dej. Nws yog lub teeb, volatile, thiab tshuaj lom kua nrog ib qho tsw me me thiab qab zib dua li ethanol. Methanol yog ib qho ntawm cov tshuaj lom neeg (nrog rau ethylene, propylene, thiab ammonia) thiab siv los tsim ntau lwm yam khoom siv xws li formaldehyde, acetic acid, thiab plastics. Methyl acetate specifications muaj xws li:
- Nws qhov hnyav yog 04 g. mol-1.
- Nws melting point yog -98 degree.
- Nws qhov kub thiab txias yog 7 degree.
- Nws qhov ceev yog 791 g / cm³.

Kev siv ntawm Methanol
Methanol yog ib qho tseem ceeb organic compound nrog ntau yam kev siv nyob rau hauv ntau lub lag luam. Hauv qab no yog qee qhov kev siv tseem ceeb ntawm methanol:
Roj Additive
Methanol tuaj yeem sib xyaw nrog lwm cov roj, xws li roj av thiab diesel, ua cov roj methanol ntxiv los txhim kho kev ua haujlwm roj. Nws pab nce tus naj npawb octane, txo cov pa phem emissions, thiab txhim khu lub cav combustion efficiency. Raws li lwm lub zog tivthaiv, methanol roj tau nce nqi rau nws cov txiaj ntsig ib puag ncig.
Muaj Raw Khoom
Kev lag luam methanol yog cov khoom siv tseem ceeb rau kev tsim ntau yam tshuaj, xws li formaldehyde, acetic acid, acetone, thiab hluavtaws roj hmab. Cov khoom lag luam hauv qab no tau siv dav hauv kev tsim khoom, kev ua liaj ua teb, thiab kev lag luam tshuaj.
Solvent thiab Cleaning Agent
Methanol yog ib qho zoo methanol hnyav thiab tu tus neeg sawv cev. Nws yog feem ntau siv los ntxuav ntau qhov chaw thiab tshem tawm cov roj thiab roj. Tsis tas li ntawd, methyl cawv yog siv rau hauv kev tsim ntawm lwm cov tshuaj ntxuav thiab tshuaj kho qhov chaw.
Tshuaj Synthesis
Methanol tuaj yeem hloov mus rau hauv formaldehyde los ntawm cov tshuaj tiv thaiv oxidation thiab siv ntxiv los ua ke rau lwm cov organic tebchaw. Nws tuaj yeem ua rau muaj ntau yam tshuaj los tsim cov tshuaj muaj txiaj ntsig xws li acetic acid, acetone, thiab butanol, ua rau nws yog ib qho tseem ceeb ntawm cov tshuaj nruab nrab.
