The Henry's Law constant for 2,4,4-trimethyl-1-pentene is estimated as 0.746 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that 2,4,4-trimethyl-1-pentene is expected to volatilize rapidly 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 1.082 hr 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)(2) is estimated as 4.2 days(SRC). 2,4,4-Trimethyl-1-pentene's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of 2,4,4-trimethyl-1-pentene from dry soil surfaces may exist(SRC) based upon a vapor pressure of 44.7 mm Hg(3).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for 2,4,4-trimethyl-1-pentene can be estimated to be about 275(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2,4,4-trimethyl-1-pentene is expected to have moderate mobility in soil.
