Editing Azide (section)

== Preparation ==
[[Sodium azide]] is made industrially by the reaction of [[nitrous oxide]], {{chem2|N2O}} with [[sodium amide]] {{chem2|NaNH2}} in [[liquid ammonia]] as [[solvent]]:<ref>{{Greenwood&Earnshaw2nd|page=433}}</ref>

:{{chem2|N2O + 2 NaNH2 → [[Sodium azide|NaN3]] + [[Sodium hydroxide|NaOH]] + [[Ammonia|NH3]]}}

Many inorganic azides can be prepared directly or indirectly from sodium azide. For example, [[lead azide]], used in [[detonator]]s, may be prepared from the [[Salt metathesis reaction|metathesis reaction]] between [[lead nitrate]] and sodium azide. An alternative route is direct reaction of the metal with [[silver azide]] dissolved in [[liquid ammonia]].<ref>{{cite journal | title=A New Route to Metal Azides |journal=Angewandte Chemie |volume=53 |issue=50 |pages=13695–13697 | doi=10.1002/anie.201404561|year=2014 |last1=Müller |first1=Thomas G. |last2=Karau |first2=Friedrich |last3=Schnick |first3=Wolfgang |last4=Kraus |first4=Florian |pmid=24924913 }}</ref> Some azides are produced by treating the [[carbonate]] [[Salt (chemistry)|salt]]s with [[hydrazoic acid]].
