Dab tsi yog cov khoom ntawm methyl acetate (cas 79 20 9)?

Methyl acetate, kuj hu uaacetic acid methyl esterlos yogmethyl ethanoate, yog cov kua ntshiab, flammable nrog tus yam ntxwv, tsis tsw ntxhiab tsw zoo li qee cov kua nplaum los yog ntsia thawv polish tshem tawm. Methyl acetate muaj cov yam ntxwv zoo ib yam li nws cov analog ethyl acetate.

Methyl acetate (cas 79 20 9) yog siv los ua cov kuab tshuaj hauv cov kua nplaum thiab cov ntsia thawv polish tshem tawm, hauv tshuaj lom neeg, thiab rau kev tshem tawm. Nws yog ib qho uas tsis yog -polar (lipophilic) rau tsis muaj zog polar (hydrophilic) aprotic hnyav. Methyl ethanoate muaj solubility ntawm 25% hauv dej ntawm chav tsev kub. Thaum kub siab nws miscibility nrog dej yog ntau dua. Methyl acetate tsis ruaj khov nyob rau hauv lub xub ntiag ntawm muaj zog aqueous bases los yog acids.
