Description
Summary:The objectives of this research were (1) to develop an accurate and sensitive method of analysis for nitroguanidine alone and in the presence of other explosives, (2) to characterize the products resulting from the chemical degradation of nitroguanidine and (3) to determine the rates of degradation of nitroguanidine under acidic, basic and neutral conditions. This study showed that nitroguanidine can be separated and identified in a mixture of other explosives by using either thin layer or high pressure liquid chromatography. Quantitative analysis, based on high pressure liquid chromatography, can be carried out. Nitroguanidine was found to be stable in water and in dilute acid, but to decompose instantly in concentrated (greater than 6N) acid to CO2 and a nitrogen oxide. A kinetic study of hydrolysis by base, to give N20 and NH3, showed the reaction to be pseudo-first order. The reaction was found to be subject to specific base catalysis.
