The Henry's Law constant for acetoin is estimated as 1.0X0-5 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that acetoin 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 2 days(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 28 days(SRC). Acetoin's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Acetoin is expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.7 mm Hg(SRC), determined from a fragment constant method(3).

The Koc of acetoin is estimated as 2(SRC), using a water solubility of 1.0X10+6 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that aetoin is expected to have very high mobility in soil.

The Henry's Law constant for isovaleric acid was measured as 8.33X10-7 atm-cu m/mole(1). This value indicates that isovaleric acid will volatilize slowly from water surfaces(2,SRC). Based on this Henry's Law constant, the estimated volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec) is estimated as approximately 45 days(2,SRC). The estimated 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 330 days(2,SRC). In addition, a pKa of 4.78 for isovaleric acid(3) indicates that isovaleric acid will not significantly volatilize from water as it will exist predominately in the ionic form under environmental pHs(SRC). Isovaleric acid's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). Isovaleric acid is not expected to volatilize from dry soil surfaces(SRC) based on a measured vapor pressure of 0.44 mm Hg(4).

The Koc of isovaleric acid is estimated as approximately 100(SRC), using a measured log Kow of 1.16(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that isovaleric acid is expected to have high mobility in soil(SRC).

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).
