Decomposition of Nitroglycerin

4C₃H₅N₃O₉ → 12CO₂ + 10H₂O + 6N₂ + O₂

Aperçu

Nitroglycerin decomposes explosively, producing a large volume of hot gases (carbon dioxide, water vapor, nitrogen, and oxygen) almost instantaneously. The detonation velocity exceeds 7700 m/s. Alfred Nobel's invention of dynamite (nitroglycerin absorbed in diatomaceous earth) made it safer to handle.

Exemple du quotidien

Nitroglycerin is used medically in small doses as a vasodilator to treat angina (chest pain) and heart conditions.

Importance industrielle

While largely replaced by safer explosives, nitroglycerin remains important in some demolition and mining applications. Its medical use as a vasodilator continues to save lives.
