メチルアセチレンとプロパジエンの混合物 化学特性,用途語,生産方法

• 化学的特性

  Colorless, liquefied gas.A mixture containing 60–66.5% methylacetylene and propadiene, with the balance being propane and butane.

• 使用

  Industrial fuel gas for cutting, welding, brazing, heat treating, and metallizing.

• 一般的な説明

  Methylacetylene-propadiene stabilized is a colorless gas with an acetylene like odor. Methylacetylene and propadiene mixture,stabilized is shipped as a liquefied gas under its vapor pressure. Contact with the liquid can cause frostbite. Methylacetylene and propadiene mixture,stabilized is easily ignited. The vapors are heavier than air. Any leak can either be liquid or vapor. Methylacetylene and propadiene mixture,stabilized can asphyxiate by the displacement of air. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket.

• 空気と水の反応

  Highly flammable.

• 反応プロフィール

  METHYLACETYLENE-PROPADIENE GAS MIXTURE presents a dangerous fire and explosion hazard when exposed to heat, flame or sparks or strong oxidizing agents. The liquid material in cylinders contains about 30% propadiene. Detonation may occur at 95°C [MCA Case History No. 632]. Reacts vigorously with strong oxidizing agents. Reaction with silver nitrate forms an acetylide igniting at 150°C [Grignard, 1935, vol. 3, p. 175]. Violent explosions occurring at low temperatures in ammonia synthesis equipment have been traced to the addition products of dienes and oxides of nitrogen produced from the interaction of nitrogen oxide and oxygen. [Bretherick, 1995].

• 危険性

  Flammable gas; dangerous fire risk. Toxic by inhalation. Central nervous system impairment.

• 健康ハザード

  Simple asphyxiant. Toxicology of propadiene component not fully established. Contact with liquid may burn eyes and cause frostbite of skin.

• 火災危険

  Behavior in Fire: Containers may explode.

• 安全性プロファイル

  A flammable gas mixture. To fight fire, stop flow of gas. When heated to decomposition it emits acrid smoke and irritating fumes.
