  • Laurent and Gerhardt give it the formula, C_ {2} N (NO_ {2}) Ag_ {2}, and thus suppose it to contain nitryl, NO_ {2}.

  • When cellulose in any form, such as cotton, is brought into contact with strong nitric acid at a low temperature, a nitrate or nitro product, containing nitryl, or the NO_ {2} group, is produced.

  • It is only necessary to bring the hydrocarbon into contact with strong nitric acid, when the reaction takes place, and one or more of the hydrogen atoms of the hydrocarbon are replaced by the nitryl group (NO_ {2}).

  • The work suggests the nighttime form of nitrogen oxides reacts with haze particles containing chloride to form nitryl chloride, which in turn forms chlorine atoms and regenerate the smog-forming nitrogen oxides when the sun rises.

  • The bit of chloride lingering in the air can react with nitrogen oxides, formed when fuel is burned at high temperature, to form nitryl chloride, a forerunner of chlorine atoms, the most reactive form of chlorine.

  • The plan was to sample nitryl chloride levels in marine air, which computer models predicted would not exceed 50 parts per trillion.

  • Before leaving, the scientists decided to test the equipment they would use to detect airborne nitryl chloride on the cruise by sampling the air in Boulder, a mile above sea level.

  • Those levels turned out to be comparable to what the scientists later recorded on the research cruise, indicating the computer models greatly underestimate nitryl chloride in the air near the Earth's surface.
