The Henry's Law constant for hydroquinone is estimated as 4.7X10-11 atm-cu m/mole(SRC) derived from its vapor pressure, 2.4X10-5 mm Hg(1), and water solubility, 7.2X10+4 mg/L(2). This Henry's Law constant indicates that hydroquinone is expected to be essentially nonvolatile from water and moist soil surfaces(3). Hydroquinone 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 hydroquinone is estimated as 240(SRC). According to a classification scheme(2), this estimated Koc value suggests that hydroquinone is expected to have moderate mobility in soil. Hydroquinone can exhibit chemisorption to transition metal-containing particulate matter via reaction with the copper oxide/silca surfaces present(3).
