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.

Yuav Ua Li Cas Ua Tau Zoo Ua Kua Acetic Acid (CAS 64-19-7)?
Thaum tuav cov acetic acid, nws yog ib qho tseem ceeb kom nco ntsoov ntau yam kev ceev faj txog kev nyab xeeb. Tsis txhob ntxiv dej rau cov tshuaj no, thiab nco ntsoov khaws cov acetic acid kom deb ntawm qhov chaw kub, qhov hluav taws xob, lossis nplaim taws. Yog tias ua haujlwm nrog acetic acid nyob rau hauv qhov chaw tsis zoo, hnav tiv thaiv ua pa tsim nyog. Piv txwv li:
- Hnab looj tes
- Splash tsom iav
- Cov khaub ncaws tiv thaiv
Dab tsi yog qhov chaw cia rau Acetic acid kua (CAS 64-19-7)?
Acetic acid 99% yuav tsum muab khaws cia rau hauv qhov chaw pom zoo kom deb ntawm qhov chaw sov lossis lwm qhov chaw taws teeb. Khaws nws cais ntawm cov ntaub ntawv tsis sib xws, suav nrog oxidizers, txo cov neeg ua haujlwm, hlau, acids, thiab alkalis. Khaws acetic acid nyob rau hauv lub thawv ntim rau hauv qhov chaw txias, zoo - qhov cua.
Kev nyab xeeb yog qhov tseem ceeb tshaj plaws thaum tuav cov tshuaj muaj kev phom sij xws li acetic acid.
