methyl acetate (MeOAc) feem ntau siv rau dab tsi?

Methyl acetate (MeOAc, CAS 79-20-9), tseem hu ua acetic acid methyl ester, yog ib qho tsis muaj xim, tsis muaj zog organic ester nrog qab zib, txiv hmab txiv ntoo tsw. Nws ua ke ntawm cov tshuaj lom neeg tsawg, siab solubility, thiab evaporation sai ua rau nws muaj ntau yam hnyav hnyav thiab tshuaj lom neeg nruab nrab hauv ntau qhov kev lag luam.

Feem ntau siv kev lag luam

• Organic Solvent: Dav siv nyob rau hauv cov xim, inks, adhesives, thiab ntxuav cov neeg ua haujlwm raws li cov organic hnyav.
• Resin thiab Xim Ntau Lawm: Hauv kev tsim cov resin thiab xim, methyl acetate yog cov khoom siv tseem ceeb, txhim kho cov khoom zoo xws li txheej zaj duab xis hardness thiab puas.
• Fragrance Manufacturing: Muaj ib qho txawv aroma, methyl acetate kuj ua hauj lwm nyob rau hauv cov khoom noj khoom haus thiab naj hoom industries raws li ib tug tshuaj tsw qab tivthaiv kom muab cov scents rau cov khoom.
• Chemical Synthesis: Tsis tas li ntawd, methyl acetate ua haujlwm ua haujlwm nruab nrab hauv kev tsim lwm yam tshuaj, suav nrog qee yam yas, tshuaj, thiab dyes.
• Extraction Agent: Nyob rau hauv cov txheej txheem tshuaj extraction, methyl acetate tuaj yeem rho cov roj thiab lwm cov khoom siv sib txuas los ntawm cov khoom cog thiab tsiaj txhu.

Cov ntaub ntawv ntxiv ntawm Methyl Acetate

Dab tsi yog cov khoom ntawm methyl acetate (MeOAc)?

Methyl acetate, tseem hu ua acetic acid methyl ester, yog cov organic ester uas muaj cov pab pawg ua haujlwm heteroatom.

Chemical Properties

• Flammability: Flash point -10 degree, tawg txwv 3.1% -16.0% (los ntawm ntim). Vapors tsim tawg sib xyaw nrog huab cua.
• Hydrolysis: Hydrolyzes hauv vivo tsim methanol, uas yog ntxiv metabolized rau hauv formaldehyde thiab formic acid.
• Reactivity: Decomposes raws li UV irradiation rau CO₂, H₂, thiab CO; reacts nrog thorium oxide ntawm qhov kub thiab txias los tsim acetone thiab lwm yam khoom.

Dab tsi yog qhov chaw cia rau methyl acetate (MeOAc)?

Thaum tuav cov methyl acetate, nws raug nquahu kom ua haujlwm hauv qhov dej zoo - qhov cua, nyob deb ntawm qhov chaw kub thiab qhib nplaim taws. Khaws cov thawv ntim kom nruj rau hauv qhov chaw txias, qhuav. Rau kev sim lossis kev siv hauv kev lag luam, cov cuab yeej tiv thaiv tsim nyog xws li lub tshuab ua pa thiab cov hnab looj tes tiv thaiv yuav tsum hnav kom ruaj ntseg.
