The Henry's Law constant for n-pentane is 1.25 atm-cu m/mole(1). This Henry's Law constant indicates that n-pentane 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 hours(3). 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 3.4 days(3). n-Pentane's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). n-Pentane is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 514 mm Hg(4).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of n-pentane can be estimated to be 72(SRC). According to a classification scheme(2), this estimated Koc value suggests that n-pentane is expected to have high mobility in soil.
