The Henry's Law constant for isoamyl acetate is 5.87x10-4 atm-cu m/mole. This Henry's Law constant indicates that isoamyl acetate 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)(3) is estimated as 2 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)(3) is estimated as 5 days(SRC). Isoamyl acetate's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of isoamyl acetate from dry soil surfaces may exist(SRC) based upon a vapor pressure of 5.6 mm Hg(4).

The Koc of isoamyl acetate is estimated as 130(SRC), using a log Kow of 2.25(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that isoamyl is expected to have high mobility in soil.
