| Volatilization | The Henry's Law constant for cyclohexanol is 4.40X10-6 atm-cu m/mole(1). This Henry's Law constant indicates that cyclohexanol is expected to volatilize from water surfaces(2). 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)(2) is estimated as 8.4 days(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 64 days(SRC). Cyclohexanol's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Cyclohexanol is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.657 mm Hg(3).

| Soil Adsorption | The Koc of cyclohexanol is estimated as 11(SRC), using a log Kow of 1.23(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that cyclohexanol is expected to have very high mobility in soil.
