The Henry's Law constant for 2-mercaptobenzothiazole is estimated as 4.1X10-11 atm-cu m/mole(SRC) derived from its vapor pressure, 2.25X10-8 mm Hg(1), and water solubility, 120 mg/L(2). This Henry's Law constant indicates that 2-mercaptobenzothiazole is expected to be essentially nonvolatile from water surfaces(3). 2-Mercaptobenzothiazole's estimated Henry's Law constant indicates that volatilization from moist soil surfaces is not expected to occur(SRC). 2-Mercaptobenzothiazole is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

The Koc of 2-mercaptobenzothiazole was measured as 677, 326 and 1360 in California sandy loam, California clay loam and California sandy soil respectively(1). The Koc of 2-mercaptobenzothiazole was measured as 2130, 3560 and 2590 in three different sediments(1). The Koc of 2-mercaptobenzothiazole was measured as 915, 863, 1429 and 1829 in Drummer silty clay loam, Spinks sandy loam, Ray silt loam and Lintonia sandy loam soil respectively(1). According to a classification scheme(2), these estimated Koc values suggest that 2-mercaptobenzothiazole is expected to have moderate to slight mobility in soil. The pKa of 2-mercaptobenzothiazole is 7.03(1), indicating that this compound will exist partially 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(3).

The Henry's Law constant for 4-thiocresol is estimated as 3.6X10-4 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that 4-thiocresol is expected to volatilize from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life of the neutral species from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 3 hrs(SRC). The volatilization half-life of the neutral species from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 5.2 days(SRC). A pKa of 6.82(3) for 4-thiocresol indicates that the anionic form of 4-thiocresol will exist in slightly acidic to basic waters and the anionic form is not expected to volatilize from water(SRC). 4-Thiocresol's Henry's Law constant(1) indicates that volatilization of the neutral species from moist soil surfaces may occur(SRC). However, 4-thiocresol in the anionic form is not expected to volatilize. 4-Thiocresol is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.807 mm Hg(4).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for 4-thiocresol can be estimated to be 430(SRC). According to a classification scheme(2), this estimated Koc value suggests that 4-thiocresol is expected to have moderate mobility in soil. The pKa of 4-thiocresol is 6.82(3) indicating that the anionic form of 4-thiocresol will exist in slightly acidic to basic soils and anions are expected to have higher mobility than the neutral species(SRC). Volatilization from moist soil surfaces is not expected to be an important fate process for the anionic species.

The Henry's Law constant for 2-mercaptoehtanol is estimated as 1.8X10-7 atm-cu m/mole(SRC) derived from its vapor pressure, 1.76 mm Hg(1), and an assigned value for water solubility of 1.00X10+6 mg/L (miscible)(2). This Henry's Law constant indicates that 2-mercaptoethanol is expected to be essentially nonvolatile from water surfaces(3). 2-Mercaptoethanol's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may not occur(SRC). 2-Mercaptoethanol is expected to volatilize from dry soil surfaces(SRC) based upon its extrapolated vapor pressure(1).

The Henry's Law constant for methyl mercaptan is estimated as 0.0031 atm-cu m/mole(SRC) derived from its vapor pressure, 1,510 mm Hg(1), and water solubility, 15,400 mg/L(2). This Henry's Law constant indicates that methyl mercaptan 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 0.8 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 2.8 days(SRC). Methyl mercaptan's Henry's Law constant indicates that volatilization from moist soil surfaces is expected to occur(SRC). Methyl mercaptan is expected to volatilize rapidly from dry soil surfaces based upon its vapor pressure and because it is a gas a temperatures above 6 deg C(SRC). However, gaseous methyl mercaptan gas has been found to strongly adsorb to moist and dry soil surfaces suggesting that adsorption might be an environmental sink for methyl mercaptan(4). Therefore, the importance of volatilization from soil surfaces may be attenuated by adsorption(SRC).
Literature: (1) Daubert TE, Danner RP; Physical and Thermodynamic Properties of Pure Chemicals Data Compilation. Washington, DC: Taylor and Francis (1989) (2) Hine J, Mookerjee PK; J Org Chem 40: 292-8 (1975) (3) Lyman WJ et al; Handbook of Chemical Property Estimation Methods. Washington, DC: Amer Chem Soc pp. 15-1 to 15-29 (1990) (4) Smith KA et al; Soil Sci 116: 313-9 (1973)

Using a structure estimation method based on molecular connectivity indices(1), the Koc of methyl mercaptan can be estimated to be 13(SRC). According to a classification scheme(2), this estimated Koc value suggests that methyl mercaptan is expected to have very high mobility in soil. Gaseous methyl mercaptan has been observed to partition to soils(3). For example, when gaseous methyl mercaptan was passed over six air-dried and moist (50% field capacity) soils, 2.4-32.1 mg/g and 2.2-21.4 mg/g of methyl mercaptan rapidly adsorbed to the dry and moist soils, respectively(3). Neither the capacity or rate of sorption was correlated to soil pH, organic matter content, or clay content; sterile controls ruled out the involvement of microorganisms(3); it was suggested that adsorption to soil surfaces might be an environmental sink for gaseous methyl mercaptan(3).

The Henry's Law constant for ethyl mercaptan is 4.53X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that ethyl mercaptan 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 2.4 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 3.2 days(SRC). Ethyl mercaptan's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Ethyl mercaptan is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 529 mm Hg(3).
