Volatilization | The Henry's Law constant for 2-ethylhexyl acetate was estimated as 1.5X10-3 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This value indicates that 2-ethylhexyl acetate will volatilize from water surfaces(2,SRC). 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) is estimated as approximately 5 hours(2,SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec) is estimated as approximately 130 hours(2,SRC). 2-Ethylhexyl acetate's Henry's Law constant(1) indicates that volatilization from moist soil surfaces is expected(SRC). 2-Ethylhexyl acetate is expected to volatilize from dry soil surfaces based on a vapor pressure of 0.23 mm Hg at 25 deg C(3).

Soil Adsorption | The Koc of 2-ethylhexyl acetate is estimated as approximately 2,500(SRC), using an estimated log Kow of 3.74(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that 2-ethylhexyl acetate is expected to have slight mobility in soil(SRC).
