Methyl acetate, tseem hu ua MeOAc, acetic acid methyl ester lossis methyl ethanoate, yog carboxylate ester nrog cov tshuaj CH3COOCH3. Acetic acid, methyl ester yog cov kua ua pa nrog lub cim ntxhiab tsw zoo ntawm qee qhov ci thiab ntsia thawv polish remover. Methyl Acetate yog qee zaum siv los ua cov kuab tshuaj, ua lub cev tsis muaj zog thiab lipophilic, tab sis nws cov txheeb ze zoo ethyl acetate yog cov kuab tshuaj uas nquag ua kom tsis tshua muaj tshuaj lom thiab tsawg soluble hauv dej. Methyl acetate muaj solubility ntawm 25% hauv dej hauv chav tsev. Thaum txhawb kub nws solubility hauv dej yog qhov siab dua. Methyl acetate tsis ruaj khov nyob rau hauv qhov muaj qhov muaj zog aqueous puag los yog kua qaub kua qaub. Methyl acetate yog VOC raug zam. Cov ntawv ceeb toom pom muaj nyob rau hauv cov txiv apple, txiv tsawb, qab zib thiab kua txiv qab zib, kua txiv kab ntxwv, dub currants, zaub txhwb, txiv quav ntswv nyoos, txiv duaj, txiv duaj, txiv moj coos, txiv puv luj, pos nphuab, zaub qhwv, lws suav, paj suav, roj peppermint, kua txob, qhob cij, cheeses, butter kua mis nyeem qaub, nqaij nyuj, npias, cognac, rum, cawv, cider, sherry, txiv hmab txiv ntoo, cocoa, kas fes, filbert, txiv laum huab xeeb, zib ntab, taum pauv, txiv ntseej, txiv hmab txiv ntoo, txiv hmab txiv ntoo brandies, fig, gin, kiwifruit, clary sage, arrack thiab nectarine. Methyl acetate yog siv los ua cov kuab tshuaj, cov roj, roj, thiab nitrocellulose; kev nrhiav neeg loj; raws li cov tsw qab ua kab mob; thiab kev siv tshuab ua kom tawv neeg.
