The Henry's Law constant for bis(2-ethylhexyl) hydrogen phosphite is estimated as 1.7X10-4 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that bis(2-ethylhexyl) hydrogen phosphite 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 14 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 9.6 days(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column(SRC). The estimated volatilization half-life from a model pond is 10 years if adsorption is considered(3). Bis(2-ethylhexyl) hydrogen phosphite's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). However, volatilization is expected to be attenuated by adsorption to soil (SRC). Bis(2-ethylhexyl) hydrogen phosphite is not expected to volatilize from dry soil surfaces(SRC), based upon a vapor pressure of 5.8X10-5 mm Hg(4).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of bis(2-ethylhexyl) hydrogen phosphite can be estimated to be 1.2X10+4(SRC). According to a classification scheme(2), this estimated Koc value suggests that bis(2-ethylhexyl) hydrogen phosphite is expected to be immobile in soil.
