QXB

The Henry's Law constant for sulfolane is estimated as 4.8X10-6 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that sulfolane 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 6 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 64 days(SRC). Sulfolane's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Sulfolane is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure 0.0062 mm Hg(3).

Sulfolane exhibited very high mobility in batch adsorption experiments using aquifer material from 3 natural gas plants in Canada(1). In each experiment, the soil adsorption isotherms were linear and the soil adsorption coefficient (Kd) of sulfolane was very low (Kd < 1). The corresponding Koc values in these low organic (0.2-0.9% organic carbon) materials were in the range of 4-35. The Koc value of sulfolane using a humus rich soil (pH = 6.9, 3.6% organic carbon) was 3(1). According to a classification scheme(2), this range of Koc values suggests that sulfolane is expected to have very high mobility in soil(SRC).
