The Henry's Law constant for methyl isobutyl ketone is estimated as 1.4X10-4 atm-cu m/mole(SRC) derived from its vapor pressure, 19.9 mm Hg(1), and water solubility, 19,000 mg/L (2). This Henry's Law constant indicates that methyl isobutyl 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 9 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 6 days(SRC). Methyl isobutyl ketone's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of methyl isobutyl ketone from dry soil surfaces may exist based upon its vapor pressure(1).

The Koc of methyl isobutyl ketone is estimated as 120(SRC), using a log Kow of 1.31(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that methyl isobutyl ketone is expected to have high mobility in soil.
