The Henry's Law constant for 4-xylene is measured as 6.90X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that 4-xylene 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 3.1 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)(2) is estimated as 4.1 days(SRC). 4-Xylene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 4-Xylene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 8.84 mm Hg(3).

Koc values of 246 and 540 have been measured for 4-xylene in silt and sandy loam soils respectively(1). A Koc value of 204 was measured for 4-xylene using sandy aquifer materials(2). A median experimental Koc value of 295 has also been reported(3). According to a classification scheme(4), these Koc values suggest that 4-xylene is expected to have moderate to low mobility in soil. A soil leaching column study estimated a 4-xylene Koc of 331 using a chromatographic methodology(5). Another soil column leaching study estimated a Koc range of 118-298 based on HPLC measurement(6).

The Henry's Law constant for n-pentanoic acid is 4.72X10-7 atm-cu m/mole(1). This Henry's Law constant indicates that n-pentanoic acid is expected to be essentially nonvolatile from water surfaces(2). Volatilization of the ionized form from water surfaces is not expected to be an important fate process(SRC). Pentanoic acid is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.96X10-1 mm Hg(3).
Literature: (1) Khan I et al; J Atmos Chem 22:285-302 (1995) (2) Lyman WJ et al; Handbook of Chemical Property Estimation Methods. Washington, DC: Amer Chem Soc pp. 15-1 to 15-29 (1990) (3) Daubert TE, Danner RP; Physical and Thermodynamic Properties of Pure Chemicals Data Compilation. Washington, DC: Taylor and Francis (1989)

The Koc of n-pentanoic acid is estimated as 140(SRC), using a log Kow of 1.39(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that n-pentanoic acid is expected to have high mobility in soil. In aqueous solution, n-pentanoic acid adsorbed 15.4 and 37.9% onto the clay minerals kaolinite and montmorillonite, respectively, after 144 hours at 22 deg C(4). The pKa of n-pentanoic acid is 4.84(5), indicating that this compound will partially exist in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(6).

The Henry's Law constant for propylene glycol is estimated as 1.3X10-8 atm-cu m/mole(SRC) derived from its vapor pressure, 0.13 mm Hg(1), and assigned value for water solubility of 1X10+6 mg/L (miscible)(2). This Henry's Law constant indicates that propylene glycol is expected to be essentially nonvolatile from water surfaces(3). Propylene glycol is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

The Koc of propylene glycol is estimated as 1(SRC), using a log Kow of -0.92(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that propylene glycol is expected to have very high mobility in soil(SRC).

A pKa of 4.87(1) indicates propionic 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(2). Propionic acid is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure of 3.35 mm Hg(3).

The Koc of propionic acid is estimated as 36(SRC), using a log Kow of 0.33(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that propionic acid is expected to have very high mobility in soil. The pKa of propionic acid is 4.87(4), indicating that this compound will primarily exist in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).
