ChEBI: Dinitrogen pentaoxide is a nitrogen oxide. | [Preparation]
Nitrogen pentoxide is obtained by dehydration of pure nitric acid by phosphorus(V) oxide at low temperatures around -10°C:
2HNO3 + P2O5 → 2HPO3 + N2O5. | [Hazard]
Nitrogen pentoxide is toxic by ingestion and can produce mouth burn. Skin contact can cause irritation. |
