Abstract

Abstract The decomposition of sodium nitrite in air was investigated at 623 and at 923 K. The following eight variables and their effects on sodium nitrite decomposition were studied: temperature, oxygen, nitrogen, carbon dioxide, water, gas flow rate, sample size and sample surface area. Temperature had the greatest influence on the decomposition of sodium nitrite, which was manifested by increased basicity of the salt, discoloration, and formation of nitrate and carbonate in the nitrite.
