Volatilization | The Henry's Law constant for methyl palmitate is estimated as 0.009 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that methyl palmitate 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 approximately 5 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 approximately 6.5 days(SRC). Methyl palmitate's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). The volatilization half-life from a model pond 2 m deep is estimated to be about 60 hours ignoring adsorption; when considering maximum adsorption the volatilization half-life increases to 150 days(3). Methyl palmitate is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.00006 mm Hg(4).

Soil Adsorption | Using a structure estimation method based on molecular connectivity indices(1), the Koc for methyl palmitate can be estimated to be about 18,000(SRC). According to a classification scheme(2), this estimated Koc value suggests that methyl palmitate is expected to be immobile in soil.
