NO-Nitric Oxide
Nitric oxide, the chemical formula is NO, the molecular weight is 30.01, is a nitrogen oxide compound, the valence of nitrogen is +2. It is a colorless and odorless gas, slightly soluble in water, soluble in ethanol and carbon disulfide. At room temperature, NO is easily oxidized to nitrogen dioxide, and can also react with halogens to form halogenated nitrosyl (NOX). Nitrogen monoxide has strong oxidizing properties, and can easily catch fire when it comes in contact with combustibles and organic matter. Encountered explosive combination of hydrogen. Contact with air will emit a brownish-yellow mist with acidic oxidizing properties. Nitric oxide is relatively inactive, but it is easily oxidized into nitrogen dioxide in the air, and the latter is strongly corrosive and toxic. The harmful combustion products are nitrogen oxides.
Nitric oxide is produced by reacting aqueous nitric acid with gaseous sulfur dioxide in a gas-liquid contact reactor. The reaction is conducted in the presence of a stoichiometric excess of nitric acid to minimize the production of byproduct nitrous oxide and nitrogen. The nitric oxide product gas is chilled sufficiently to freeze most of the water and byproduct nitrogen dioxide contained in the nitric oxide product gas.
Nitric oxide is used in oxidation and chemical vapor deposition processes in semiconductor production, and as a standard gas mixture for atmospheric monitoring. It is also used to make nitric acid and silicone oxide film and carbonyl nitrosyl. It can also be used as a bleaching agent for rayon and a stabilizer for propylene and dimethyl ether. Supercritical solvent. Used in the manufacture of nitric acid, nitroso carboxyl compounds, rayon bleaching. It is used as a stabilizer of organic reaction in medical clinical experiment to assist diagnosis and treatment. It is also used as a stabilizer for nitric acid, rayon bleaching agent, propylene and dimethyl ether.
