II | [Safety Profile]
material explodes at
room temperature. When heated to
decomposition it emits acrid smoke and
fumes. See also PEROXIDES. |
| Hazard Information | Back Directory | [General Description]
Available only as a 25% solution. Pure material poses a severe explosion hazard. Used as an initiator in polymerization reactions. | [Air & Water Reactions]
Highly flammable. May ignite spontaneously if exposed to air. | [Reactivity Profile]
Dipropionyl peroxide(in solution,content≤27%) is a good oxidizing agent. May cause ignition of organic compounds on contact . Reacts violently with strongly reduced material such as sulfides, nitrides, and hydrides. Many produce explosions or generate gases (toxic and nontoxic). Generally, dilute solutions (<70%) are safe, but the presence of a catalyst (often a transition metal such as cobalt, iron, manganese, nickel, or vanadium) as an impurity may even then cause rapid decomposition, a buildup of heat, and even an explosion. May become explosive when evaporated to dryness or near-dryness. May explode from heat, contamination or loss of temperature control. | [Hazard]
Strong oxidizing agent, may explode if
shocked or heated.
