The Henry's Law constant for 2,3-butanediol is estimated as 2.9X10-8 atm-cu m/mole(SRC) derived from its vapor pressure, 0.24 mm Hg(1), and an assigned value for water solubility of 1.0X10+6 mg/L (miscible)(2). This Henry's Law constant indicates that 2,3-butanediol is expected to be essentially nonvolatile from water surfaces(3). 2,3-Butanediol is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure of 0.24 mm Hg(1).

The Koc of 2,3-butanediol is estimated as 7.5(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 2,3-butanediol is expected to have very high mobility in soil.
