The Henry's Law constant for 1-butyl mercaptan is 4.54X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that 1-butyl mercaptan 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 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 days(SRC). 1-Butyl mercaptan's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 1-Butyl mercaptan is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 45.5 mm Hg(3).

The Koc of 1-butyl mercaptan is estimated as 410(SRC), using a log Kow of 2.28(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1-butyl mercaptan is expected to have moderate mobility in soil.
