프로피오닐 퍼옥사이드

프로피오닐 퍼옥사이드 화학적 특성, 용도, 생산

• 용도

  Initiator in polymerization reactions, such as the high-pressure polymerization of ethylene.

• 정의

  Avail- able as a 25% solution in a high-boiling hydrocar- bon, flash p 125F (51.6C).

• 일반 설명

  Available only as a 25% solution. Pure material poses a severe explosion hazard. Used as an initiator in polymerization reactions.

• 공기와 물의 반응

  Highly flammable. May ignite spontaneously if exposed to air.

• 반응 프로필

  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.

• 위험도

  Strong oxidizing agent, may explode if shocked or heated.

• Safety Profile

  material explodes at room temperature. When heated to decomposition it emits acrid smoke and fumes. See also PEROXIDES.
