Useful:

• Chemical Classes: Toxic Gases & Vapors -> Oxidizers
• Canonical SMILES: N(=O)[O]
• Inhalation Risk: A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
• Effects of Short Term Exposure: The substance is corrosive to the eyes, skin and respiratory tract. Exposure at high concentrations could cause asphyxiation due to swelling in the throat. Inhalation of the gas or vapour may cause lung oedema. Exposure far above the OEL could cause death. The effects may be delayed. Severe effects may occur following a prolonged symptom-free period. Medical observation is indicated.
• Effects of Long Term Exposure: The substance may have effects on the lungs. This may result in impaired functions and decreased resistance to infection.

Technology Process of Nitrogen Dioxide

There total 667 articles about Nitrogen Dioxide which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 98.0%

ammonium nitrate → nitrogen (7727-37-9) + nitrogen(II) oxide (10102-43-9) + Nitrogen dioxide (10102-44-0) + dinitrogen monoxide (10024-97-2)

Guidance literature:

at 220-260°C, nearly 98% N2O, 2% N2; troces of NO and NO2 (0.001%);

Reference yield: 68.0%

hydrogen (1333-74-0) + oxygen (80937-33-3) + nitrogen(II) oxide (10102-43-9) → Nitrogen dioxide (10102-44-0) + dinitrogen monoxide (10024-97-2)

Guidance literature:

With catalyst:Ag/alumina; In gas; byproducts: H2O; gas mixt. contg. 500 ppm NO, 6% (V/V) O2 and 1% H2 (V/V) in He at 250 °C on Ag/alumina catalyst;
