용도Sodium azide is used in making othermetal azides, therapeutically to control bloodpressure, as a propellant for automotivesafety bags, as a preservative for laboratoryreagents, as an analytical reagent, andin organic synthesis. It is also used as anantifading reagent for immunofluorescence(Boeck et al. 1985).
생산 방법Sodium azide can be prepared from sodium metal and liquid ammonia in the presence of ferric chloride. The amide formed is treated with nitrous oxide to produce the azide.
Sodium azide is prepared by reacting sodium amide with nitrous oxide. The amide is heated with nitrous oxide at 200°C or its solution in liquid ammonia is treated with nitrous oxide at ambient temperature: 2NaNH2 + N2O → NaN3 + NaOH + NH3.
