The Henry's Law constant for amylene is 0.110 atm-cu m/mole(1). This Henry's Law constant indicates that amylene 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 2.5 hrs(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 80 hrs(SRC). Amylene's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of amylene from dry soil surfaces may exist(SRC) based upon a vapor pressure of 468 mm Hg(3).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for amylene can be estimated to be about 68(SRC). According to a classification scheme(2), this estimated Koc value suggests that amylene is expected to have high mobility in soil.
