Gefahrenhinweise
Regulatory InformationChemical: Nitrogen oxide (N2O5)
Hazards Summary
Nitrogen oxides are toxic to the lung by inhalation; Effects include upper respiratory tract irritation, cough, conjunctivitis, dyspnea, headache, and delayed pulmonary edema; About half of those who survive pulmonary edema develop bronchiolitis obliterans; May form nitric acid (corrosive) on contact with body moisture; Toxicology of nitrogen pentoxide is largely unknown; [Reference #1] See Nitrogen dioxide.
Toxikologische Informationen
Adverse EffectsMethemoglobinemia - The presence of increased methemoglobin in the blood; the compound is classified as secondary toxic effect
Chemie und Industrie
Verwendung und Herstellung
UsesUsed in chloroform solution as a nitrating agent; [Merck Index]
Anwendungen
VerwendenAs nitrating agent in chloroform solution.
Darstellung
synthetischeNitrogen pentoxide is obtained by dehydration of pure nitric acid by phosphorus(V) oxide at low temperatures around -10°C: 2HNO3 + P2O5 → 2HPO3 + N2O5.
