ntshiab acetic acid formula
Dab tsi yog cov khoom ntawm ntshiab acetic acid (CAS 64-19-7)?
Acetic acid, tshuaj, ntau tshaj 80% acid yog ib tug ntshiab xim tsis muaj dej aqueous tov nrog ib tug pungent tsw. COLORLESS LIQUID nrog PUNGENT ODOUR. Cov kua uas tsis muaj xim lossis muaj kua muaj kua qaub, kua qaub - zoo li tsw. Cov kua dej tsis muaj xim lossis muaj kuab muaj kua qaub, kua qaub - zoo li tsw.
Kev nthuav tawm cov khoom tseem ceeb hauv qab no:
Lub cev muaj zog
- Cov tsos mob: tsis muaj xim tsis muaj pob tshab kua nrog ib qho pungent, irritating tsw.
- Solubility: Yooj yim soluble hauv dej, ethanol, diethyl ether, thiab lwm yam; insoluble hauv carbon disulfide.
- Cov ntsiab lus khov: 16.6℃(anhydrous acetic acid ua cov xim tsis muaj xim raws li solidification).
Cov khoom siv tshuaj
- Acetic acid yog hygroscopic, txhais tau tias nws nyiam nqus dej noo. Nws sib tov nrog ethyl cawv, glycerol, ether, carbon tetrachloride thiab dej thiab reacts nrog oxidants thiab bases. Concentrated acetic acid yog corrosive thiab tawm tsam ntau cov hlau uas tsim cov nplaim hluav taws kub los yog tawg.
- Lwm yam khoom
- Corrosiveness: Vapors khaus qhov muag thiab qhov ntswg; aqueous daws yog weakly acidic thiab corrosive.
- Cov ntawv thov kev lag luam: Cov khoom tseem ceeb ntawm vinegar (3% -5% concentration), siv rau cov khoom noj khoom haus, organic synthesis, thiab lwm yam.
