Acrylic acid

CAS RN: 79-10-7

Volatilization

The pKa of 4.25(1) indicates acrylic acid will exist almost entirely in the anion form at pH values of 5 to 9, and, therefore, volatilization from water surfaces and moist soil is not expected to be an important fate process(2). The potential for volatilization of acrylic acid from dry soil surfaces may exist(SRC) based upon a vapor pressure of 3.97 mm Hg(3).
