The Henry's Law constant for 2(5H)-furanone is estimated as 9.7X10-6 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that 2(5H)-furanone 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 3.6 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 29 days(SRC). 2(5H)-Furanone's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 2(5H)-Furanone is not expected to volatilize from dry soil surfaces(SRC) based upon a an estimated vapor pressure of 0.98 mm Hg(SRC), determined from a fragment constant method(3).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of 2(5H)-furanone can be estimated to be 6(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2(5H)-furanone is expected to have very high mobility in soil.
