What is Di-(2-ethylhexyl)peroxydicarbonate?

Chemical properties

It is colorless liquid with unpleasant odor. Thermally unstable with required continuous refrigeration below -10°C (-14°F). Refer to the Code for the Storage of Organic Peroxide Formulations. Storage incompatibility includes strong acids, oxidizing agents, alkaline materials, reducing agents, and amines. Also, it should be stored away from excessive heat, sources of ignition, and reactive materials (12b).

General Description

Di-(2-ethylhexyl)peroxydicarbonate is particularly sensitive to temperature rises. Above a given "Control Temperature" they decompose violently. They are generally stored or transported in a solvent slurry.

Reactivity Profile

DI-(2-ETHYLHEXYL) PEROXYDICARBONATE decomposes violently or explosively at temperatures 0-10° C. owing to self-accelerating exothermic decomposition; Several explosions were due to shock, heat or friction; amines and certain metals can cause accelerated decomposition [Bretherick, 1979 p. 156], Danger of explosion when dry

Safety Profile

Moderately toxic by ingestion. When heated to decomposition it emits acrid smoke and irritating fumes. See also PEROXIDES, ORGANIC
