The Henry's Law constant for 1-undecene is estimated as 1.48 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that 1-undecene is expected to volatilize rapidly 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 1 hr(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 5 days(SRC). However, the volatilization half-life does not take into account the effects of adsorption. This is apparent from the results of two EXAMS model runs, one in which the effect of adsorption was considered, yielding an estimated half-life of 21 days in a model pond 2 m deep, and one in which the effect of adsorption was ignored, yielding an estimated half-life of 42 hrs in a model pond 2 m deep(3). 1-Undecene's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). 1-Undecene is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.493 mm Hg(4).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for 1-undecene can be estimated to be about 3180(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1-undecene is expected to have slight mobility in soil.
