| Environmental Impact | Chloromethyl methyl ether might possibly escape into the environment in exhaust gases
associated with its use as a chemical intermediate. It would not be found in waste water due to its
very rapid hydrolysis (half-life < 1 sec). Its half-life in humid air has been measured to be 3.5-6
min and 6.5 hr in 2 studies.

| Environmental Fate | TERRESTRIAL FATE: The fate of chloromethyl methyl ether in moist soil is unknown.
However since it hydrolyzes so rapidly, it will be expected to disappear rapidly from moist soil.
AQUATIC FATE: Chloromethyl methyl ether will hydrolyze instantaneously in water (half-life <
1 sec) . The reaction products are methanol, formaldehdye, and HC1 .
ATMOSPHERIC FATE: Chloromethyl methyl ether will hydrolyze in humid air (half-life 3.5 min
to 6.5 hr)(1,2). However, results suggest that the hydrolysis is surface catlyzyed and therefore
may not represent the true half-life in and the atmospheric room air or outside air. A
half-life would be determined by its reaction with photochemically produced hydroxyl radicals
(estimated 5.7 days .
