A pKa of 4.31(1) indicates phenylacetic acid will exist almost entirely in the anion form at pH values of 5 to 9(2) and therefore volatilization from water surfaces is not expected to be an important fate process. Phenylacetic acid is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(3).
Literature: (1) Dean JA; Lange's Handbook of Chemistry 13th ed NY, NY: McGraw-Hill, Inc p. 5-53 (1985) (2) Doucette WJ; pp. 141-188 in Handbook of Property Estimation Methods for Chemicals. Boethling RS, Mackay D, eds. Boca Raton, FL: Lewis Publ (2000) (3) Perry RH, Green D; Perry's Chemical Engineer's Handbook 6th ed NY, NY: McGraw-Hill, Inc p. 3-59 (1984)

Koc values of 31, 26, and 28 were experimentally determined for phenylacetic acid in three specific soils: a Podzol (pH = 2.8, sand = 89.2%, silt = 8.2%, and clay = 2.6%), an alfisol (pH = 6.7, sand = 69.7%, silt = 14.4%, and clay = 15.9%) and sediment from Lake Constance (pH = 7.1, sand = 5.5%, silt = 58.8%, and clay = 35.7%), respectively(1). According to a recommended classification scheme(2), these Koc values suggest that phenylacetic acid is expected to have very high mobility in soil(SRC). The pKa of phenylacetic acid is 4.31(3), 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(4).

The Henry's Law constant for 2-phenylethanol estimated from its vapor pressure, 0.0868 mm Hg at 25 deg C(1), and water solubility, 16,000 mg/L(2), is 1.5X10-7 atm-cu m/mol(SRC). Using this value for the Henry's Law constant, one can estimate a volatilization half-life of 2-phenylethanol in a model river 1 m deep flowing at 1 m/s with a wind speed of 3 m/s is 46.5 days(3,SRC). 2-Phenylethanol's relatively low Henry's Law constant and vapor pressure suggest that volatilization from moist and dry soil surfaces will be minimal(SRC).
Literature: (1) Daubert TE, Danner RP; Data Compilation Tables of Properties of Pure Compounds NY, NY: Amer Inst for Phys Prop Data (1989) (2) Valvani SC et al; J Pharm Sci 70: 502-7 (1981) (3) Lyman WJ et al; Handbook of Chemical Property Estimation Methods, NY: McGraw-Hill Chapt 15 (1982)

Using an estimation method based on molecular connectivity indices(1), the Koc for 2-phenylethanol is estimated to be 29(SRC). According to a suggested classification scheme(2), this Koc value suggests that 2-phenylethanol will have very high mobility in soil(SRC).

A pKa of 4.84(1) indicates isobutyric acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces and moist soil is not expected to be an important fate process(2). Isobutyric acid is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.81 mm Hg(3).

The Koc of isobutyric acid is estimated as 77(SRC), using a log Kow of 0.94(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that isobutyric acid is expected to have high mobility in soil. The pKa of isobutyric acid is 4.84(4), indicating that this compound will exist almost entirely 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).

InChI=1/C5H10O2/c1-4(2)3-5(6)7/h4H,3H2,1-2H3,(H,6,7

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).
