Abstract:

This article is a study of the interaction of technical sodium superoxide NaO2, 85 pure with water vapor at -10, -5, 0, and 20 C. At temperatures from -10 to 0 C, oxygen and hydrated sodium peroxide were the end products. The octohydrate Na2O2.8H2O was the most stable hydrate. The amount of heat evolved in the reaction was determined. At 20 C, however, both NaO2 and Na2O2 rapidly decomposed with rapid evolution of oxygen and heat. Hydrated sodium hydroxide NaOH.H2O was the solid end product of the reaction. The article is indicative of continuing Soviet efforts to find the most economical method of employing oxygen-producing reagents for air purification in closely confined areas e.g., in manned space vehicles. Temperatures for the study from -10 to 20 C were obviously selected to simulate biologically acceptable conditions. Author
