Isobutyraldehyde or isobutyl aldehyde [UN2045] [Flammable liquid]

The Henry's Law constant for isobutyraldehyde is estimated as 1.8X10-4 atm-cu m/mole(SRC) based upon its vapor pressure, 173 mm Hg(1), and water solubility, 8.9X10+4 mg/l(2). This Henry's Law constant indicates that isobutyraldehyde 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 3.6 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 4.6 days(SRC). Isobutyraldehyde's estimated Henry's Law constant(1,2) indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of isobutyraldehyde from dry soil surfaces may exist(SRC) based upon a vapor pressure of 173 mm Hg(1).

The Koc of isobutyraldehyde is estimated as 8(SRC), using a water solubility of 8.9X10+4(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that isobutyraldehyde is expected to have very high mobility in soil(SRC).
