Mesityl oxide, suitable for neutral marker for measuring electroosmotic flow (EOF), ~98%

The Henry's Law constant for mesityl oxide is estimated as 3.67X10-5 atm-cu m/mole(SRC) derived from its vapor pressure, 8.21 mm Hg(1), and water solubility, 28,900 mg/L(2). This Henry's Law constant indicates that mesityl oxide is expected to volatilize from water surfaces(3). 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)(3) is estimated as 17 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)(3) is estimated as 11 days(SRC). Mesityl oxide's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of mesityl oxide from dry soil surfaces may exist(SRC) based upon its vapor pressure(1).

The Koc of mesityl oxide is estimated as 15(SRC), using a water solubility of 28,900 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that mesityl oxide is expected to have very high mobility in soil.
