Volatilization | The Henry's Law constant for ethyl methyl ether is estimated as 6.7X10-4 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that ethyl methyl ether is expected to volatilize 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 approximately 3.3 hours(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 approximately 3.4 days(2,SRC). Ethyl methyl ether's Henry's Law constant(1,SRC) indicates that volatilization from moist soil surfaces may occur(SRC). Volatilization of ethyl methyl ether from dry soil surfaces is expected(SRC) |
Soil Adsorption | The Koc of ethyl methyl ether is estimated as approximately 48(SRC), using an estimated log Kow of 0.56(1,SRC) and a regression-derived equation(2,SRC). According to a classification scheme(3), this estimated Koc value suggests that ethyl methyl ether is expected to have very high mobility in soil(SRC). |
