| Volatilization | The Henry's Law constant for dipropyl ketone is estimated as 2.4X10-4 atm-cu m/mole(SRC) derived from its vapor pressure, 5.2 mm Hg at 20 deg C(1), and water solubility, 3.19X10+3 mg/L(2). This Henry's Law constant indicates that dipropyl ketone 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 3.7 hours(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 5.4 days(SRC). Dipropyl ketone's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of dipropyl ketone from dry soil surfaces may exist(SRC) based upon its vapor pressure(1).

| Soil Adsorption | The Koc of dipropyl ketone is estimated as 178(SRC), using a log Kow of 2.04(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that dipropyl ketone is expected to have moderate mobility in soil.
