Dab tsi yog cov khoom ntawm acetic acid kua 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.
   

Dab tsi yog kev siv ntawm acetic acid kua?

Hauv cov ntawv thov kev lag luam, acetic acid kua ua haujlwm ua cov khoom siv tshuaj lom neeg tseem ceeb:

• Kev siv tshuaj lom neeg: Kwv yees li 50% ntawm acetic acid kua yog siv los tsim cov yas acetate monomer (VAM), uas yog ntxiv ua rau polyvinyl cawv (PVA) thiab cov nplaum; Lwm daim ntawv thov loj yog synthesizing purified terephthalic acid (PTA) rau polyester (PET) yas thiab fibers.
• Cov kuab tshuaj thiab Esters: Ester cov kuab tshuaj zoo li ethyl acetate thiab butyl acetate tau siv dav hauv cov txheej txheem, inks, thiab tshuaj.
• Kev Lag Luam Khoom Noj: Ua haujlwm ua kua qaub (E260) thiab khaws cia hauv cov khoom noj khoom haus, cov kaus poom, thiab lwm yam.
• Pharmaceutical Applications:
• Ua haujlwm ua ib qho nruab nrab hauv kev tsim cov tshuaj aspirin, sulfonamide tshuaj, thiab vitamin B1.
• Lwm yam kev siv:
• Kho pH nyob rau hauv textiles, coagulates latex nyob rau hauv cov roj hmab ntau lawm, thiab yooj yim kho cov hlau nto thiab dej khib nyiab neutralization.
• Nrog thoob ntiaj teb kev tsim khoom txhua xyoo ntau tshaj kaum lab tons, nws cov derivatives tseem ceeb heev rau kev lag luam niaj hnub.
