Propanoic acid; Propionic acid; Metacetonic Acid C3H6O2 CAS 79-09-4

Lub npe: Propionic acid

CAS Nr: 79-09-4

Cov mis mos molecular: C3H6O2

Nyob rau hauv ib txwm kub thiab siab, propionic acid yog ib tug tsis muaj kob thiab ntshiab oily kua nrog unpleasant rancidity thiab pungent tsw, uas yuav miscible nrog dej, ethanol, chloroform thiab ether.

Propionic acid yog ib qho tsis muaj zog electrolyte (Ka=1.34 × 10-5). Nws cov tshuaj aqueous yog tsis muaj zog acidic tab sis corrosive heev, thiab nws cov vapor yog irritating rau ntawm daim tawv nqaij thiab ua pa ib ntsuj av.
