Oxygen decomposition

At typical catalyst temperatures of 800°C to 940°C, nitric oxide (NO) is thermodynamically unstable and slowly decomposes into nitrogen and oxygen. Decomposition losses are minimized by avoiding excessive catalyst contact time and by rapidly cooling the gases as they exit the converter. To achieve ammonia conversions of 93% to 98% the catalyst contact time must be as short as 0.0010 to 0.0001 seconds104. 

HAZARD RISK Very dangerous fire and explosion hazard when exposed to heat or flame explosive reaction with epoxy resin, sodium hydroxide and oxygen decomposition emits acrid smoke and fiimes NFPA Code H 3 F 4 R 2. 

Hypochlorous acid is unstable and decomposes very easily to liberate oxygen. Decomposition rate is not violent, however, and for some purposes may even be increased by the use of a cobalt or nickel salt to act as a catalyst. The action of the salts, especially those of the alkalies or alkaline earths,. may be increased by the addition of carbon dioxide or acids because of the more rapid liberation of the hypochlorous acid caused thereby. This property furnishes a method of control when these substances are used for oxidation. j... 

Nitrous oxide at room temperature and atmospheric pressure is a colorless gas with a barely perceptible sweet odor and taste. It is nonflammable but will support combustion. At elevated temperatures, nitrous oxide decomposes into nitrogen and oxygen. Decomposition in the absence of catalysts is negligible at temperatures below 1200°F (649°C). Nitrous oxide is moderately soluble in water, alcohol, and oils. Unlike some higher oxides of nitrogen, nitrous oxide does not affect the acidity of water solutions.
