  • 定義 ChEBI: The sodium salt of hydrogen azide (hydrazoic acid).
  • 一般的な説明 A colorless crystalline solid. Density 1.85 g / cm3. Burns in air and may explode if large quantities are involved. Toxic by ingestion. Toxic oxides of nitrogen are produced in fires.
  • 空気と水の反応 Soluble in water. Addition of water to Sodium azide which was heated caused a violent reaction, [Angew. Chem. 1952, 64, 169]. Dust may form an explosive mixture in air.
  • 反応プロフィール Sodium azide is unstable. Decomposes rapidly or explosively at about 300°C [Hawley]. May explode if shocked. Forms violently explosive products if exposed to carbon disulfide. Can be sensitized toward decomposition by metal salts (especially heavy metal salts such as silver chloride) or by traces of strong acids [Sax, 9th ed., 1996, p. 298].
  • 健康ハザード Can cause death by affecting the central nervous system. Contact may cause burns to skin and eyes.
  • 火災危険 When heated to decomposition, Sodium azide emits very toxic fumes of nitrogen oxides; explosive. Forms explosive-sensitive materials with some metals such as lead, silver, mercury or copper. May form toxic hydrazoic acid fumes in fire. Containers may explode in fire. Avoid acids, benzoyl chloride and potassium hydroxide; bromine; carbon disulfide; copper; lead; nitric acid; barium carbonate; sulfuric acid; chromium (II) hypochlorite, dimethyl sulfate, water, dibromomalononitrile, lead, silver, copper, mercury. Hazardous polymerization may not occur.
