The Henry's Law constant for acetoin is estimated as 1.0X0-5 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that acetoin is expected to volatilize from water surfaces(2). 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)(2) is estimated as 2 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)(2) is estimated as 28 days(SRC). Acetoin's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Acetoin is expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.7 mm Hg(SRC), determined from a fragment constant method(3).

The Koc of acetoin is estimated as 2(SRC), using a water solubility of 1.0X10+6 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that aetoin is expected to have very high mobility in soil.
