Useful:

• Chemical Classes: Toxic Gases & Vapors -> Acids, Inorganic
• Canonical SMILES: [N+](=O)(O)[O-]
• Inhalation Risk: A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20 °C.
• Effects of Short Term Exposure: The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation may cause asthma-like reactions (RADS). Exposure could cause asphyxiation due to swelling in the throat. Inhalation of high concentrations may cause pneumonitis and lung oedema.
• Effects of Long Term Exposure: Repeated or prolonged inhalation may cause effects on the teeth. This may result in tooth erosion. The substance may have effects on the upper respiratory tract and lungs. This may result in chronic inflammation of the respiratory tract and reduced lung function . Mists of this strong inorganic acid are carcinogenic to humans.

Technology Process of Nitric Acid

There total 520 articles about Nitric Acid 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:

water (7732-18-5) + 1-(2-bromo-2-nitrovinyl)-4-nitrobenzene (7559-38-8) → bromonitromethane (563-70-2) + hydrogen bromide (10035-10-6,12258-64-9) + nitric acid (7697-37-2,78989-43-2) + cis-nitrous acid (7782-77-6)
