The Henry's Law constant for 2-methylpentaldehyde is estimated as 3.7X10-4 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This value indicates that 2-methylpentaldehyde 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 5.3 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 4.7 days(2,SRC). 2-Methylpentaldehyde's vapor pressure, 17.9 mm Hg(3,SRC) and Henry's Law constant(1,SRC) indicate that volatilization from dry and moist soil may occur(SRC).

The Koc of 2-methylpentaldehyde is estimated as approximately 44(SRC), using an experimental water solubility of 4200 mg/L at 25 deg C(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that 2-methylpentaldehyde has very high mobility in soil(SRC).
