The Henry's Law constant for methyl n-butyrate is 2.05X10-4 atm-cu m/mole(1). This Henry's Law constant indicates that methyl n-butyrate 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 4 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 5 days(SRC). Methyl n-butyrate's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of methyl n-butyrate from dry soil surfaces may exist(SRC) based upon a vapor pressure of 32.3 mm Hg(3).

The Koc of methyl n-butyrate is estimated as 120(SRC), using a log Kow of 1.29(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that methyl n-butyrate is expected to have high mobility in soil(SRC).
