Volatilization | The Henry's Law constant for 2-methyl-1-pentanol is estimated as 4.3X10-5 atm-cu m/mole(SRC) from its experimental values for vapor pressure, 1.92 mm Hg at 25 deg C(1), and water solubility, 6000 mg/L at 25 deg C(2). This value indicates that 2-methyl-1-pentanol will volatilize from water surfaces(3,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 24 hours(3,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 10 days(3,SRC). 2-Methyl-1-pentanol's vapor pressure(1) and Henry's Law constant(1,2,SRC) indicate that volatilization from dry and moist soil surfaces may occur(SRC).

Soil Adsorption | The Koc of 2-methyl-1-pentanol is estimated as approximately 37(SRC), using a measured water solubility of 6000 mg/L(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that 2-methyl-1-pentanol has very high mobility in soil(SRC).
