The Henry's Law constant for 3-methylbutanal is estimated as 4.0X10-4 atm-cu m/mole(SRC) derived from its vapor pressure, 50 mm Hg(1), and water solubility, 1.4X10+4 mg/L(2). This Henry's Law constant indicates that 3-methylbutanal is expected to volatilize rapidly 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 4 days(SRC). 3-Methylbutanal's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of 3-methylbutanal from dry soil surfaces may exist(SRC) based upon its vapor pressure(1).

The Koc of 3-methylbutanal is estimated as 23(SRC), using a water solubility of 1.4X10+4 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 3-methylbutanal is expected to have very high mobility in soil.
