In chemistry, azide is a linear, polyatomic anion with the formula N−3 and structure N=N =N . It is the conjugate base of hydrazoic acid HN3. Organic azides are organic compounds with the formula RN3, containing the azide functional group. The dominant application of azides is as a propellant in air bags. Visa mer Sodium azide is made industrially by the reaction of nitrous oxide, N2O with sodium amide NaNH2 in liquid ammonia as solvent: N2O + 2 NaNH2 → NaN3 + NaOH + NH3 Many inorganic azides can be prepared directly or indirectly … Visa mer Azide is isoelectronic with carbon dioxide CO2, cyanate OCN , nitrous oxide N2O, nitronium ion NO+2 and cyanogen fluoride NCF. Per Visa mer About 251 tons of azide-containing compounds are produced annually, the main product being sodium azide. Sodium azide NaN3 … Visa mer • Pentazenium • Pentazolate (cyclo-N5 ) Visa mer Azide salts can decompose with release of nitrogen gas. The decomposition temperatures of the alkali metal azides are: NaN3 (275 °C), … Visa mer Azides are explosophores and poisons. Sodium azide is as toxic as sodium cyanide (with an oral LD50 of 27 mg/kg in rats) and can be absorbed through the skin. Heavy metal azides, such as lead azide are primary high explosives detonable when heated or shaken.
