colorless, hexagonal crystal(s) [MER06]
Colorless hexagonal crystal; volatile solid; density 1.642 g/cm3 at 18°C; melts at 30°C; decomposes at 47°C; soluble in water forming nitric acid; soluble in chloroform with some decomposition.
As nitrating agent in chloroform solution.
Nitrogen pentoxide is obtained by dehydration of pure nitric acid by phosphorus(V) oxide at low temperatures around -10°C:
2HNO3 + P2O5 → 2HPO3 + N2O5.
ChEBI: Dinitrogen pentaoxide is a nitrogen oxide.
Nitrogen pentoxide is toxic by ingestion and can produce mouth burn. Skin contact can cause irritation.
