Chlorine azide (ClN3) is an inorganic compound. It was discovered by Friedrich Raschig in 1908.[1] More so than other azides, ClN3 is highly explosive. In undiluted condition, it usually detonates violently whatever the temperature, without apparent provocation.[2]

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.[3]

When treated with ammonia it is conceivable that one or more of the three possible azinamines, NH2N3, NH(N3)2, and N(N3)3 may be formed.

Explosive characteristics

Chlorine azide is highly sensitive. It will explode without provocation and is too sensitive to be used commercially. Explosive reaction with 1,3-butadiene, ethane, ethylene, methane, propane, phosphorus, silver azide, sodium. Reacts with water or steam to produce toxic and corrosive fumes of hydrochloric acid.[4]
