The Henry's Law constant for 2-pentanone is 8.36X10-5 atm-cu m/mole(1). This Henry's Law constant indicates that 2-pentanone 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 12 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)(2) is estimated as 6.6 days(SRC). 2-Pentanone's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 2-Pentanone is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 35.4 mm Hg(3).

The Koc of 2-pentanone is estimated as 75(SRC), using a log Kow of 0.91(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 2-pentanone is expected to have high mobility in soil(SRC).
