Abstract:

SRI International conducted a study of the thermal decomposition of a newly developed energetic material ammonium dinitramide ADN, as well as, for comparison, two related materials ammonium nitrate AN, and nitramide NH2HO2. Brief studies were also performed with RDX and with AgNNO2CH2CN, which was tested as a potential source of the suspected RDX intermediate CH2NNO2. The former portion of the work has resulted in a manuscript, which is being submitted for publication and is included as an appendix to this final report. A summary of the work and its principal findings is given below, beginning with the results for ADN itself. Pyrolysis of ADN under low pressure showed acid-base dissociation like AN, but it also resulted in some decomposition to N2O, NO, and water. The onset of evolution of these species was at 90 C, and as in the case of AN, an explosive event was noted at 174 C, which is about 80 C higher than the melting point of ADN and 15 C higher than thermal decomposition in a DSC.
