Hazard Predictions

• Explosive: Reaction products may be explosive or sensitive to shock or friction
• Generates gas: Reaction liberates gaseous products and may cause pressurization
• Generates heat: Exothermic reaction at ambient temperatures (releases heat)
• Unstable when heated: Reaction products may be unstable above ambient temperatures
• Intense or explosive reaction: Reaction may be particularly intense, violent, or explosive

Although all diazonium salts should be considered potentially self-reactive, diazonium perchlorates are particularly hazardous and can explode with the slightest shock when dry (Berichte 39: 3146-8 (1996); German Pat. 258,679 (Apr. 27, 1911); ACS Monograph 146, "Perchlorates, Their Properties, Manufacture and Uses," J.C. Schumacher, Reinhold, New York (1960), 213).

In one of a number of preparations, benzenediazonium chloride was air-dried and placed in a large bottle with a screw cap. About four hours later the entire complex decomposed with considerable violence. At the time no heat or strong light was near the bottle.
