The Henry's Law constant for n-undecane is estimated as 6.1 atm-cu m/mole(SRC) derived from its vapor pressure, 0.412 mm Hg(1), and water solubility, 0.014 mg/L(2). This Henry's Law constant indicates that n-undecane is expected to 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 3.6 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 5 days(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is about 1 month if adsorption is considered(4). n-Undecane's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). n-Undecane is not expected to volatilize from dry soil surfaces based upon its vapor pressure(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of n-undecane can be estimated to be 2,600(SRC). According to a classification scheme(2), this estimated Koc value suggests that n-undecane is expected to have slight mobility in soil.
