Decomposition of Ammonium Nitrate

NH₄NO₃ → N₂O + 2H₂O

Visão geral

Ammonium nitrate decomposes at about 200 C to form nitrous oxide (laughing gas) and water. At higher temperatures or with confinement, it can decompose explosively to nitrogen, oxygen, and water. The dual nature of ammonium nitrate as both a fertilizer and explosive makes it a significant safety concern.

Exemplo do cotidiano

The 2020 Beirut explosion that devastated the city's port was caused by the detonation of improperly stored ammonium nitrate.

Importância industrial

O nitrato de amónio é um dos fertilizantes mais importantes do mundo e é também utilizado em explosivos de mineração (ANFO). Existem regulamentações rigorosas de armazenamento devido aos riscos de explosão.
