Methyl Acetate thiab Acetone
Methyl acetate (CAS 79-20-9) yog dab tsi?
Methyl acetate, tseem hu ua MeOAc, acetic acid methyl ester lossis methyl ethanoate, yog carboxylate ester nrog cov mis CH3COOCH3, Methyl acetate yog cov kua ntshiab, tsis muaj xim nrog cov txiv hmab txiv ntoo, qab zib. Methyl acetate yog ntau yam tshuaj uas muaj ntau yam kev siv. Methyl acetate yog cov kua nplaum uas muaj cov ntxhiab tsw qab uas zoo li nco txog qee cov kua nplaum thiab cov ntsia thawv polish tshem tawm.
Methyl acetate siv los ua cov kuab tshuaj, ua tsis muaj zog polar thiab lipophilic, tab sis Methyl acetate ze txheeb ze ethyl acetate yog cov kuab tshuaj ntau dua uas tsis muaj tshuaj lom thiab tsis tshua muaj dej hauv dej. Methyl acetate muaj solubility ntawm 25% hauv dej ntawm chav tsev kub. Thaum kub siab Methyl acetate solubility hauv dej yog ntau dua.
Kev siv Methyl Acetate
- Organic Solvent: Vim nws zoo heev solubility, methyl acetate yog dav siv los ua cov organic hnyav hauv cov xim, inks, adhesives, thiab tshuaj ntxuav.
- Resin thiab Xim Ntau Lawm: Hauv kev tsim cov khoom siv thiab xim, methyl acetate yog cov khoom siv tseem ceeb uas 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 siv los rho cov roj thiab lwm cov khoom siv sib txuas los ntawm cov khoom cog thiab tsiaj txhu.
Dab tsi yog acetone (cas 67-64-1)?
Acetoneyog cov kua tsis muaj xim uas tseem hu ua propanone. Nws feem ntau lees paub tias muaj kev nyab xeeb (GRAS) hauv qee qhov ntau, nrog cov tshuaj lom neeg tsawg, tab sis muaj hluav taws kub. Cov tshuaj no yog cov kuab tshuaj uas sib tov zoo nrog dej thiab evaporates sai, ua kom zoo - haum rau ntau tsev neeg thiab kev tsim khoom siv.
Kev siv Acetone
- Dav siv nyob rau hauv cov xim, ntsia thawv polish removers, adhesives, thiab plastics ntau lawm.
- Cov chav kuaj hnyav hnyav rau chromatography thiab qauv npaj.
- Degreasing thiab ntxuav tus neeg sawv cev hauv cov kab ntau lawm.
