Diisobutyryl peroxide Chemical Properties,Usage,Production
General Description
Diisobutyryl peroxide(in solution,content≤52%) is particularly sensitive to temperature rises and contamination. Above a given "Control Temperature" they decompose violently.
Reactivity Profile
Most of the isolated diacyl(including sulfonyl) 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 ISOBUTYRYL PEROXIDE in ether was being evaporated to dryness with a stream of air when Diisobutyryl peroxide(in solution,content≤52%) exploded violently, [MCA Case History No. 579]. Can generate electrostatic charges. REF [Handling Chemicals Safely, 1980. p. 250].
Flammability and Explosibility
Not classified
Safety Profile
May explode when dried at room temperature. When heated to decomposition it emits acrid smoke and fumes. See also PEROXIDES.
