Sodium azide 化学特性,用途語,生産方法

  • 化学的特性 Colorless, hexagonal crystals. Decom- poses at about 300C. Soluble in water and in liquid ammonia; slightly soluble in alcohol; hydrolyzes to form hydrazoic acid. Combustible.
  • 使用 Biomedical Sciences
    Sodium azide is a biocide that is used in making chemical preservatives that are used in laboratories and hospitals. In hospitals, it is used as a preservative in blood tests and diagnostic machines. Since the chemical is soluble, it can act as useful metabolic inhibitors that can affect the activities of numerous oxidative enzymes. Specifically, it inhibits oxidative enzymes that are involved in electron transport system respiration. However, accidents have occurred whenever sodium azide is used in a hospital setting; therefore, major bodies such as the CDC that deal with chemicals do not advise the use of the compound.
    Automobiles Airbags
    Before the 1990s, sodium azide was used in airbags. In airbags, when electricity heats sodium azide to approximately 300oC, it decomposes into two simple components, namely sodium and nitrogen gas. The decomposition of sodium azide happens very fast that the filling of the airbag with nitrogen gas occurs at a velocity of around 200 miles per hour.
    Agriculture
    Sodium azide is used for pest control due to its ready solubility in water. Nitrifying bacteria acts as a catalyst that decomposes the sodium azide solution to release nitrate, HN3, and NH4+ when added to the soil. It is noteworthy that these components have wide range of activity against nematodes, weeds, and phytopathogenic fungi that is soil-borne. The chemical is typically applied through drip irrigation to avoid reactivity of HN3 in the soil-air space that can eventually result in an active compound that can be ineffective for pest control.
    Detonators
    When combined with other metals such as copper (Cu), lead (Pb), and mercury (Hg), sodium azide becomes unstable and explosive. As such, it is mostly used as detonators due to its explosive nature.

  • 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].
  • 危険性 Highly toxic. Lung damage and cardiac impairment. Questionable carcinogen.
  • 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.
  • 純化方法 Crystallise sodium azide from hot water or from water by adding absolute EtOH or acetone. Also purify it by repeated crystallisation from an aqueous solution saturated at 90o by cooling it to 10o, and adding an equal volume of EtOH. The crystals are washed with acetone, and the azide is dried at room temperature under vacuum for several hours in an Abderhalden pistol. Its solubility in H2O is 42% at 18o, and in EtOH it is 0.22% at 0o. [Das et al. J Chem Soc, Faraday Trans 1 78 3485 1982, Schenk in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I pp 474-475 1963, Browne Inorg Synth 1 79 1939, Frierson Inorg Synth II 139 1946.] HIGHLY POISONOUS and potentially explosive.
