The Henry's Law constant for trans-2-pentene is estimated as 0.32 atm-cu m/mole(SRC) using a fragment constant estimation method(1). The value for the Henry's Law constant indicates that trans-2-pentene is expected to volatilize rapidly from water surfaces(2). Based on the Henry's Law constant, the half-life for volatilization of trans-2-pentene from model river water (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 1 hr(SRC). The half-life for volatilization from model lake water (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 80 hrs(SRC). The Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of trans-2-pentene from dry soil surfaces may exist(SRC) based upon a vapor pressure of 506 mm Hg(3).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for trans-2-pentene can be estimated to be about 81(SRC). According to a classification scheme(2), this estimated Koc value suggests that trans-2-pentene is expected to have a high mobility in soil.
