The Henry's Law constant for 1-pentene calculated from its vapor pressure, 635 mm Hg(1), and water solubility, 148 mg/l(2), is 0.40 atm-cu m/mole (SRC). This Henry's Law constant indicates that 1-pentene should volatilize rapidly from water surfaces(3). 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)(3) is estimated as 2.4 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)(3) is estimated as 3.3 days(SRC). 1-Pentene's Henry's Law constant(1,2) indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of 1-pentene from dry soil surfaces exists based upon its vapor pressure of 635 mm Hg(1).

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