Acetic Acid

CAS RN: 64-19-7


The Henry's Law constant for acetic acid has been experimentally determined to be 1.43X10-7 atm-cu m/mole at 25 deg C(1). This Henry's Law constant indicates that acetic acid is expected to be essentially nonvolatile from water surfaces(2). Acetic acid's Henry's Law constant indicates that volatilization from moist soil surfaces is not expected to be an important fate process(SRC). Acetic acid is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 15.7 mm Hg at 25 deg C(3).
