MSDS Information

• Dicumyl peroxide

ビス(1-フェニル-1-メチルエチル)ペルオキシド 化学特性,用途語,生産方法

• 用途

  有機過酸化物(重合触媒)

• 化学的特性

  Dicumyl peroxide is a crystalline solid that melts at 42°C. It is insoluble in water and soluble in vegetable oil and organic solvents . It is used as a high-temperature catalyst in production of polystyrene plastics. The deflagration hazard potential of this peroxide was tested using 5 g of igniter in the revised time–pressure test, but no pressure rise was produced . Noller et al. found it to be an intermediate fire hazard.

• 使用

  Dicumyl peroxide(DCP) is used:
  in vulcanization of rubber
  as a crosslinking agent in the synthesis of polylactic acid composite fibers
  in the preparation of polyethylene composites
  in the synthesis of polyamide 112/ethylene vinyl acetate copolymer blends.

• 一般的な説明

  Dicumyl peroxide is a pale yellow to white granular solid with a characteristic odor. It is used as a polymerization catalyst and vulcanizing agent.

• 反応プロフィール

  The explosive instability of the lower dialkyl peroxides (e.g., dimethyl peroxide) and 1,1-bis-peroxides decreases rapidly with increasing chain length and degree of branching, the di-tert-alkyl derivatives being amongst the most stable class of peroxides. Though many 1,1-bis-peroxides have been reported, few have been purified because of the higher explosion hazards compared with the monofunctional peroxides. Dicumyl peroxide is unlikely that this derivative would be particularly unstable compared to other peroxides in it's class, Bretherick 2nd ed., p 44 1979.

• 安全性プロファイル

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

• 純化方法

  Crystallise the peroxide from 95% EtOH (charcoal). Store it at 0o. Potentially EXPLOSIVE. [Beilstein 6 IV 3220.]
