Dipropionyl peroxide(in solution,content≤27%) Usage And Synthesis
Initiator in polymerization reactions, such as the high-pressure polymerization of ethylene.
Avail- able as a 25% solution in a high-boiling hydrocar- bon, flash p 125F (51.6C).
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.
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.
Strong oxidizing agent, may explode if shocked or heated.
material explodes at room temperature. When heated to decomposition it emits acrid smoke and fumes. See also PEROXIDES.
