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 ...
