Cov ntaub ntawv ntxiv ntawm Methyl Acetate
methyl acetate CAS No. 79-20-9 yog dab tsi?
Methyl acetate, tseem hu ua methyl ethanoate, yog cov xim tsis muaj xim, pob tshab, tsis muaj kuab lom nrog cov ntxhiab tsw ntxhiab, muaj cov tshuaj formula CH₃COOCH₃. Raws li cov khoom lag luam ntawm cov tshuaj tiv thaiv esterification ntawm acetic acid thiab methanol, nws pom kev siv dav hauv kev lag luam xws li kev tsim khoom, tshuaj engineering, thiab tshuaj.
Physical thiab Chemical Properties
Methyl acetate CAS No. 79-20-9 muaj qhov hnyav ntawm 74.08 g / mol, qhov kub ntawm 57.1 ° C, melting point ntawm -98 ° C, thiab qhov ceev ntawm 0.932 g / cm³ ntawm 20 ° C. Tsis muaj zog, nws yog yooj yim soluble nyob rau hauv feem ntau cov organic solvents (xws li, ethanol, diethyl ether) thiab me ntsis soluble nyob rau hauv dej (solubility kwv yees li 25 g / L ntawm 20 ° C). Vim nws cov ester pawg qauv, nws nthuav tawm cov khoom siv tshuaj lom neeg, ua rau hydrolysis, alcoholysis, thiab cov tshuaj ammonolysis. Piv txwv li, nyob rau hauv acidic los yog alkaline tej yam kev mob, methyl acetate yooj yim hydrolyzes tsim acetic acid thiab methanol; reacting nrog ammonia yields acetamide. Tsis tas li ntawd, nrog lub teeb nyem ntawm -10 ° C, nws raug cais raws li cov kua hluav taws xob thiab yuav tsum tau ceev kom deb ntawm qhov hluav taws kub thiab qhov chaw kub.
Dab tsi yog kev lag luam siv methyl acetate (MeOAc) cas no 79 20 9?
- Organic Solvent: Vim nws zoo heev solubility, methyl acetate (MeOAc) yog dav siv los ua cov organic hnyav nyob rau hauv coatings, inks, adhesives, thiab cov tshuaj ntxuav.
- Resin thiab Txheej Ntau Lawm: Hauv kev tsim khoom thiab txheej txheej, MeOAc ua haujlwm tseem ceeb ntawm cov khoom siv uas txhim kho cov khoom zoo xws li txheej zaj duab xis hardness thiab abrasion tsis kam.
- 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: Hauv cov txheej txheem kev rho tawm cov tshuaj, methyl acetate (MeOAc) 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 qhov chaw cia rau methyl acetate cas tsis muaj 79 20 9?
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.
