The Henry's Law constant for n-butyl alcohol is 8.81X10-6 atm-cu m/mole at 25 deg C(1). This Henry's Law constant indicates that n-butanol is expected to volatilize 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 3.7 days(SRC). 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 29 days(SRC). n-Butyl alcohol's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). n-Butyl alcohol is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 7 mm Hg(3).

The measured Koc of n-butyl alcohol is reported as 3.2(1). According to a classification scheme(2), this Koc value suggests that n-butyl alcohol is expected to have very high mobility in soil(SRC).

The Henry's Law constant for n-butanoic acid is measured as 5.35X10-7 atm-cu m/mole(1). This Henry's Law constant indicates that n-butanoic acid is expected to volatilize 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 64 days(SRC). 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 471 days(SRC). A pKa of 4.82(3) indicates n-butanoic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(4). n-Butanoic acid's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). n-Butanoic acid is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.65 mm Hg(5).

The Koc of n-butanoic acid is estimated as 64(SRC), using a log Kow of 0.79(1) and a regression-derived equation(2). Experimental Koc values for n-butanoic acid on a clastic mud (3.5% organic carbon), a lateritic muddy sand (1.3% organic carbon), and a fine carbonate sand (0.17% organic carbon) were 19.1, 27.6, and 14.7, respectively(3). According to a classification scheme(4), these estimated and experimental Koc values suggest that n-butanoic acid is expected to have very high to high mobility in soil. The percent of n-butanoic acid sorbed to a kalonite or montmorillonite clay at 22 deg C was 14.0% and 19.9% after 48 hours, respectively, which increased to 31.4% and 24.2%, respectively, after 144 hours(5). In a field study in which 100 ppm n-butanoic acid was injected underground, the retardation, relative to the linear ground-water velocity, was calculated to be 3%(6). N-butanoic acid is listed as a compound displaying an L-type adsorption isotherm, indicating that specific binding sites may be involved(7). Experimental studies in indicate that adsorption of n-butanoic acid to moist soil is dominated by attractive forces between the compound and soil and not by hydrophobic interactions(8). The pKa of n-butanoic acid is 4.82(9), indicating that this compound will primarily exist in the anion in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(10).

The Henry's Law constant for isovaleric acid was measured as 8.33X10-7 atm-cu m/mole(1). This value indicates that isovaleric acid will volatilize slowly from water surfaces(2,SRC). Based on this Henry's Law constant, the estimated volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec) is estimated as approximately 45 days(2,SRC). The estimated volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec) is estimated as approximately 330 days(2,SRC). In addition, a pKa of 4.78 for isovaleric acid(3) indicates that isovaleric acid will not significantly volatilize from water as it will exist predominately in the ionic form under environmental pHs(SRC). Isovaleric acid's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). Isovaleric acid is not expected to volatilize from dry soil surfaces(SRC) based on a measured vapor pressure of 0.44 mm Hg(4).

The Koc of isovaleric acid is estimated as approximately 100(SRC), using a measured log Kow of 1.16(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that isovaleric acid is expected to have high mobility in soil(SRC).
