The Henry's Law constant for cyclobutane is estimated as 0.14 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This value indicates that cyclobutane is expected to volatilize rapidly from water surfaces(2,SRC). Based on this Henry's Law constant, the estimated volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec) is approximately 2 hours(2,SRC). The estimated volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec) is approximately 3 days(2,SRC). Cyclobutane's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of cyclobutane from dry soil surfaces may exist(SRC) based on a vapor pressure of 1.18X10+3 mm Hg(3).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for cyclobutane can be estimated to be about 49(SRC). According to a classification scheme(2), this estimated Koc value suggests that cyclobutane is expected to have very high mobility in soil(SRC).
