Volatilization | The Henry's Law constant for diethyl adipate is estimated as 3.6X10-6 atm-cu m/mole(SRC) from its vapor pressure, 0.058 mm Hg(1), and water solubility, 4,230 mg/l(2). This Henry's Law constant indicates that diethyl adipate is expected to volatilize from water surfaces(3). 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)(3) is estimated as 10 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)(3) is estimated as 110 days(SRC). Diethyl adipate's estimated Henry's Law constant(1,2) indicates that volatilization from moist soil surfaces may occur(SRC). Volatilization from dry soil surfaces is not expected to be an important environmental fate process for diethyl adipate(SRC) based on its vapor pressure(1). |
Soil Adsorption | The Koc of diethyl adipate is estimated as 45(SRC), using a water solubility of 4,230 mg/l(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that diethyl adipate is expected to have very high mobility in soil(SRC). |
