Volatilization | The Henry's Law constant for diethyl ketone is 5.0X10-5 atm-cu m/mole(1). This Henry's Law constant indicates that diethyl ketone 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 19 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 8.6 days(SRC). diethyl ketone's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Diethyl ketone is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 37.7 mm Hg(3).

Soil Adsorption | The Koc of diethyl ketone is estimated as 82(SRC), using a log Kow of 0.99(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that diethyl ketone is expected to have high mobility in soil. Literature: (1) Hansch C et al; Exploring QSAR.
