The Henry's Law constant for vanillin for the neutral species is estimated as 2.1X10-9 atm-cu m/mole(SRC) derived from its vapor pressure, 1.18X10-4 mm Hg(1), and water solubility, 1.102X10+4 mg/L(2). This Henry's Law constant indicates that vanillin is expected to be essentially nonvolatile from water surfaces(3). Vanillin is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of vanillin can be estimated to be 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that vanillin is expected to have very high mobility in soil. The pKa of vanillin is 7.4(3), indicating that this compound will partially exist 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(4).
