Chemical compound

Chlorine azide (ClN3) is an inorganic compound that was discovered in 1908 by Friedrich Raschig.[2] Concentrated ClN3 is notoriously unstable and may spontaneously detonate at any temperature.[3]

Preparation and handling

Chlorine azide is prepared by passing chlorine gas over silver azide, or by an addition of acetic acid to a solution of sodium hypochlorite and sodium azide.[4]

Explosive characteristics

Chlorine azide is extremely sensitive. It may explode, sometimes even without apparent provocation; it is thus too sensitive to be used commercially unless first diluted in solution. Chlorine azide reacts explosively with 1,3-butadiene, ethane, ethene, methane, propane, phosphorus, silver azide, and sodium. On contact with acid, chlorine azide decomposes, evolving toxic and corrosive hydrogen chloride gas.[5]

Regulatory information

Its shipment is subject to strict reporting requirements and regulations by the US Department of Transportation.
