Record 1 2011-08-23

English

Subject field(s)
  • Chemical Elements and Compounds
Universal entry(ies)
NO
formula
10102-43-9
CAS number
DEF

A colorless poisonous gas having the formula NO which is obtained by oxidation of nitrogen or ammonia in making nitric acid or by reduction of nitrous acid, which readily reacts with oxygen at room temperature to form nitrogen dioxide, NO2, a reddish brown gas, and which is used as an intermediate in the production of nitric acid from ammonia, in the preparation of nitrosyl carbonyls, and for bleaching rayon.

OBS

It is found in variable trace quantities in the atmosphere, especially near industrial areas.

CONT

Not in itself a pollutant, in the ambient air NO converts to nitrogen dioxide, a major contributor to photochemical smog.

OBS

nitrogen monoxide: form recommended by the IUPAC (International Union of Pure and Applied Chemistry) for the systematic name corresponding to the CAS number indicated on the present record.

OBS

nitric oxide: term adopted by Environment Canada; used in the list of pollutants measured in the National Air Pollution Surveillance Network (NAPS).

Record 2 2002-02-06

English

Subject field(s)
  • Chemical Elements and Compounds
  • Air Pollution
  • Chemistry
DEF

Catalytic action of nitrogen, mainly nitric oxide, on atmospheric ozone.

CONT

It might be noted that whereas the chlorine catalysis of ozone is about six times as efficient as the nitric oxide catalysis of ozone, the conversion to "inert" hydrogen chloride is also more efficient than the conversion to "inert" nitric acid, so that the two processes are in fact comparable in overall efficiency.
