The Henry's Law constant for n-heptane is estimated as 1.8 atm-cu m/mole(SRC) derived from its vapor pressure, 46 mm Hg(1), and water solubility, 3.4 mg/L(2). This Henry's Law constant indicates that n-heptane 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 2.9 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 4.0 days(SRC). n-Heptane's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of n-heptane from dry soil surfaces may exist(SRC) based upon a vapor pressure of 46 mm Hg(1).

Literature: #In a study quantifying the passive volatilization of a synthetic gasoline and its individual components in three air-dried soils over a period of up to 16 days, n-heptane had a volatilization half-life of approximately 10 hours in a loamy sand at a depth of 50 mm(1). Using different soil types, n-heptane, at a depth of 50 mm, volatilized first from sand, followed by a loamy sand and finally a silt loam, showing that as the particle size of the soil decreased and the clay and organic content matter increased, the volatilization rate decreased(1). Complete volatilization of n-heptane from a tray containing a gasoline pool thickness of 7 mm at a temperature of 18.5 deg C occurred after approximately 5.6 hours(1). In a study in which a jet fuel mixture was incubated in freshwater from the Escambia River, FL at 25 deg C, a 99% loss of n-heptane in the controls was attributed to evaporation(2). n-Heptane as a component of missile fuel was also lost to volatilization within 5 hours when incubated with water from the Range Point salt marsh, FL(3). n-Heptane degradation was observed in active and sterile sandy loam treated with JP-4 jet fuel (10 uL per gram of soil)(4). The concentration of n-heptane at 0 time was 0.277 ug/mL in the active soil and 0.235 ug/mL in the sterile soil while the concentrations in both soils were 0 ug/mL when they were tested a second time after 5 days; evaporation was considered to be the primary removal process(4).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of n-heptane can be estimated to be 240(SRC). According to a classification scheme(2), this estimated Koc value suggests that n-heptane is expected to have moderate mobility in soil.
