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.

The Henry's Law constant for isopentanol is 1.41X10-5 atm-cu m/mol(1). Using this value for the Henry's Law constant, one can estimate that the volatilization half-life of isopentanol in a model river 1 m deep flowing at 1 m/s with a wind speed of 3 m/s is 2.55 days(2). Similarly, the half-life of isopentanol in a model lake 1 m deep with a 0.05 m/s current and a 0.5 m/s wind is 21 days(2). In view of isopentanol's relatively high vapor pressure, 2.37 mm Hg at 25 deg C(3) and moderate Henry's Law constant and low adsorptivity to soil, isopentanol would be expected to volatilize from dry and moist soil(SRC).

The Koc for isopentanol estimated from its water solubility, 26.7 mg/L(1), using recommended regression equations are 720(2) and 679(4). However, the chemicals used in developing these equations were mainly pesticides and their structures are not similar to isopentanol. The Koc for isopentanol estimated from molecular structure is 4(3). This should be a reasonable estimate for the Koc because it is close to the experimental value for the structurally similar chemical, 1-pentanol, 1.6(6). According to a suggested classification scheme(5), the estimated Kocs based on molecular structure suggests that isopentanol is very highly mobile in soil(SRC).
