The Henry's Law constant for dimethylhydroxy furanone is estimated as 1.5X10-5 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that dimethylhydroxy 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 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 25 days(SRC). Dimethylhydroxy furanone's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Dimethylhydroxy furanone is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 0.008 mm Hg(SRC), determined from a fragment constant method(1); however, dimethylhydroxy furanone does emit an odor(3) even though it exists as a solid.

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