| Environmental Impact | Diepoxybutane is not produced commercially in the USA and its major use is as a
research chemical. If released to soil, diepoxybutane is predicted to be very mobile in wet soils
and should hydrolyze to 1,2,3,4-tetrahydroxybutane. If released to water, diepoxybutane is
expected to undergo hydrolysis to 1,2,3,4-tetrahydroxybutane. Diepoxybutane is not expected to
react with alkyl peroxy radical in water, volatilize from water, bioconcentrate in aquatic organisms
or adsorb to sediments. If released to the atmosphere, vapor phase diepoxybutane is predicted to
be removed primarily by reaction with photochemically generated hydroxyl radicals (half-life 2.4
hours). In addition, removal via wet deposition may also be possible.

| Environmental Fate | TERRESTRIAL FATE: If released to soil, diepoxybutane is predicted to be very mobile
in wet soils and should hydrolyze to 1,2,3,4-tetrahydroxybutane. Diepoxybutane is expected to
volatilize from dry soil surfaces.
AQUATIC FATE: If released to water, diepoxybutane should hydrolyze to form
1,2,3,4-tetrhydroxybutane. Diepoxybutane is not expected to react with alkyl peroxy radical,
volatilize from water surfaces, bioconcenatrate in aquatic organisms or adsorb to sediments.
ATMOSPHERIC FATE: If released to the atmosphere, vapor phase diepoxybutane is predicted
to be removed primarily by reaction with photochemically generated hydroxyl radicals. Removal
via wet deposition may also be possible considering the solubility of diepoxybutane in water.
Diepoxybutane is not expected to react with ozone or adsorb onto airborne particulate matter.
