The Henry's Law constant for acetyl acetone is estimated as 2.3X10-6 atm-cu m/mole(SRC) derived from its vapor pressure, 2.96 mm Hg(1), and water solubility, 166,000 mg/L(2). This Henry's Law constant indicates that acetyl acetone is expected to volatilize from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(3) is estimated as 16 days(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 120 days(SRC). Acetyl acetone's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of acetyl acetone from dry soil surfaces may exist(SRC) based upon its vapor pressure(1).

The Koc of acetyl acetone is estimated as 39(SRC), using a log Kow of 0.40(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that acetyl acetone is expected to have very high mobility in soil.
