Dab tsi yog qhov ceev ntawm methyl acetate (MeOAc) kua?

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

Methyl Acetate (MeOAc) yog cov kua ntshiab, tsis muaj xim uas muaj cov ntxhiab tsw ester zoo ib yam li cov kua nplaum thiab cov ntsia hlau tshem tawm. Nws yog flammable heev nrog ib tug flashpoint ntawm -10℃C thiab ib tug flammability ntsuam xyuas ntawm 3. Methyl acetate feem ntau yog siv nyob rau hauv tsawg toxicity solvents xws li kua nplaum, ntsia thawv polish removers.

Dab tsi yog qhov ceev ntawm methyl acetate (MeOAc) kua?

Methyl acetate (C₃H₆O₂) yog cov kua tsis muaj xim, tsis muaj kuab lom nrog lub qab ntxiag qab zib, tsw qab zoo li txiv apples lossis txiv pos nphuab. Raws li qhov yooj yim ester ntawm acetic acid, nws muaj lub teeb molecular hnyav (74.08 g / mol),Tsawg ceev (0.932 g / mL ntawm 20 degree), thiab qhov chaw txias txias (-98 degree). Nws boils ntawm 56.9℃thiab yooj yim vaporizes nyob rau hauv me me tshav kub. Me ntsis soluble hauv dej, nws yog tag nrho miscible nrog cov organic solvents xws li ethanol thiab diethyl ether.

Kev Siv Methyl Acetate (MeOAc) Liquid yog dab tsi?

Methyl Acetate (MeOAc) kua yog thawj siv yog nyob rau hauv zus tau tej cov acetic anhydride, uas yog ntxiv txheej txheem los npaj cellulose acetate los yog ua hauj lwm raws li ib tug acetylating neeg sawv cev nyob rau hauv tshuaj, dyes, fragrances, thiab organic synthesis. Nws kuj tseem ua haujlwm nyob rau hauv kev tsim cov tawv tawv thiab cov tshuaj tsw qab, ua cov roj extraction tus neeg sawv cev, thiab ua cov khoom siv chromatographic txheem thiab hnyav.

Gneebio yog ib tug ntseegmethyl acetate hmoov (CAS 79-20-9) tus neeg muag khoom, muab tus nqi ncaj qha rau lub Hoobkas, ntau qhov ntau, thiab xa khoom sai thoob ntiaj teb.
