The Henry's Law constant for cyclododecane is estimated as 1.54 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that cyclododecane is expected to volatilize rapidly 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 4 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)(2) is estimated as 5 days(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 9 years if adsorption is considered. Cyclododecane's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Cyclododecane is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 0.029 mm Hg(SRC), determined from a fragment constant method(4).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of cyclododecane can be estimated to be 5,300(SRC). According to a classification scheme(2), this estimated Koc value suggests that cyclododecane is expected to be immobile in soil.
