ABSTRACT
Diethylene glycol dimethyl ether may be released to the environment via effluents at sites where it is produced or used as a solvent and an anhydrous reaction medium for organometallic synthesis. Diethylene glycol dimethyl ether is not expected to undergo hydrolysis or direct photolysis in the environment. The complete miscibility of diethylene glycol dimethyl ether in water suggests that volatilization, adsorption and bioconcentration are not important fate processes. This is supported by the estimated Henry's Law constant, which indicates that volatilization of diethylene glycol dimethyl ether from natural waters and moist soil should be extremely slow. Yet, it may evaporate from dry surfaces, especially when present in high concentrations such as in spill situations. A low estimated log BCF suggests diethylene glycol dimethyl ether should not bioconcentrate among aquatic organisms.
