The Henry's Law constant for ethyl n-butyrate is estimated as 4.4X10-4 atm-cu m/mole(SRC) derived from its vapor pressure, 14.0 mm Hg(1), and water solubility, 4,900 mg/L(2). This Henry's Law constant indicates that ethyl n-butyrate 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 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)(3) is estimated as 5 days(SRC). Ethyl n-butyrate's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of ethyl n-butyrate from dry soil surfaces may exist(SRC) based upon its vapor pressure(1).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of ethyl n-butyrate can be estimated to be 20(SRC). According to a classification scheme(2), this estimated Koc value suggests that ethyl n-butyrate is expected to have very high mobility in soil.
