| Volatilization | The Henry's Law constant for isooctyl alcohol is estimated as 9.2X10-5 atm-cu m/mole(SRC) derived from its extrapolated vapor pressure, 0.344 mm Hg(1), and water solubility, 640 mg/L(2). This Henry's Law constant indicates that isooctyl alcohol is expected to volatilize from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(3) is estimated as 14 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 7.8 days(SRC). Isooctyl alcohol's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Isooctyl alcohol is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

| Soil Adsorption | The Koc of isooctyl alcohol is estimated as 125(SRC), using a water solubility of 640 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that isooctyl alcohol is expected to have high mobility in soil.
