Volatilization | The Henry's Law constant for furfuryl alcohol is estimated as 7.9X10-8 atm-cu m/mole(SRC) derived from its vapor pressure, 0.609 mm Hg(1), and an assigned value for water solubility of 1X10+6 mg/L (miscible)(2). This Henry's Law constant indicates that furfuryl alcohol is expected to be essentially nonvolatile from water surfaces(3). Furfuryl alcohol's estimated Henry's Law constant indicates that volatilization from moist soil surfaces is not expected to occur(SRC). Furfuryl alcohol may volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

Soil Adsorption | The Koc of furfuryl alcohol is estimated as 34(SRC), using a log Kow of 0.28(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that furfuryl alcohol is expected to have very high mobility in soil. The pKa of furfuryl alcohol is 9.55(4), indicating that this compound will primarily exist in its neutral form in the environment(5). Literature: (1) Hansch C et al; Exploring QSAR.
