Reaktive GruppePeroxides, Organic
Reactivity AlertsExplosive
Reactivity ProfileMost of the isolated diacyl peroxides are solids with relatively low decomposition temperatures, and are explosive, and sensitive to shock, heat, or friction. Several, particularly the lower members, will detonate on the slightest disturbance. Autocatalytic, self-accelerating decomposition, which is promoted by tertiary amines, is involved. A sample of DIISOBUTYRYL PEROXIDE in ether was being evaporated to dryness with a stream of air when it exploded violently, [MCA Case History No. 579]. Can generate electrostatic charges. REF [Handling Chemicals Safely, 1980. p. 250].
Air and Water ReactionsNo rapid reaction with air. No rapid reaction with water.
