The Henry's Law constant for phthalic acid is estimated as 2X10-11 atm-cu m/mole(SRC) derived from its vapor pressure, 6.36X10-7 mm Hg(1), and water solubility, 6965 mg/L(2). This Henry's Law constant indicates that phthalic acid is expected to be essentially nonvolatile from water surfaces(3). Phthalic acid's Henry's Law constant indicates that volatilization from moist soil surfaces will not occur(SRC). Phthalic acid is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

The Koc values were determined for an acidic forest soil (Podzol, 4.85% organic carbon, pH 2.8), an agricultural soil (Alfisol, 1.25% organic carbon, pH 6.7) and a sublimnic soil (sediment from Lake Constance, Germany, 1.58% organic carbon, pH 7.1) as 31, 2 and 2, respectively(1). According to a classification scheme(2), these Koc values suggest that phthalic acid is expected to have very high mobility in soil. Phthalic acid adsorbs strongly to aluminum and iron oxides via a surface ligand exchange reaction(3). Adsorptivity is sensitive to pH; for aluminum oxide the fraction absorbed is >0.8 below pH 6 and falls below 0.1 above pH 7.5(3).
