アセチレン化銅(II)

アセチレン化銅(II) 化学特性,用途語,生産方法

• 化学的特性

  brown-black solid; explodes [CRC10]

• 物理的性質

  Brownish black powder; insoluble in water.

• 使用

  Cupric acetylide is used as a detonator.Its applications are very limited, however,because of its high sensitivity to impact orfriction. It is susceptible to form and buildup upon prolong contact of copper metal withorganic vapors.

• 製造方法

  Copper(II) acetylide may be prepared by passing alkyl acetylene vapors over aqueous solution of ammoniacal copper salt.

• 危険性

  Copper(II) acetylide is highly sensitive to impact, friction or heat. Mild impact or heating can cause a violent explosion. In the dry state it is flammable and is more sensitive to impact or friction than copper(I) acetylide.

• 火災危険

  Cupric acetylide is much more sensitive to impact and friction than the cuprous salt. Friction heating or mild impact can result in violent explosion. In dry state, its sensitivity is much greater to impact and is flammable.

• 安全性プロファイル

  Confirmed carcinogen. Cases of berylliosis have been reported from exposure to so-called low berylhum alloys. Human systemic effects by inhalation: dyspnea, fibrosing alveolitis, weight loss, or decreased weight gain. See also BERYLLIUM COMPOUNDS and COPPER COMPOUNDS. When heated to decomposition it emits very toxic fumes of BeO.
