“…From these results, the major evolved gases were determined to be NH3, H2O, HCN, CO, N2, CH2O, CH3NH2, HNCO, CO2, N2O and HNO3. Figure 4 summarizes the thermal behavior and product generation profiles obtained from the TG-DSC-HRTOFMS data, taking into account the mass fragment values and equations (1) to (11). The ADN/MMAN/urea ternary mixture is distinguished by the formation of HNCO and CO2 as decomposition products.…”

Thermal and evolved gas analyses were carried out to assess the decomposition of an ionic liquid propellant consisting of ammonium dinitramide (ADN), methylammonium nitrate (MMAN) and urea, using thermogravimetry-differential scanning calorimetry-high resolution time of flight mass spectrometry (TG-DSC-HRTOFMS). This technique simultaneously assesses the thermal and evolved gas behavior and is able to distinguish between products having similar massto-charge ratios, based on accurate mass determinations. ADN/MMAN and ADN/MMAN/urea mixtures were found to decompose to form NH3, H2O, HCN, CO, N2, CH2O, CH3NH2, HNCO, CO2, N2O and HNO3, and possible reaction schemes for the decomposition processes were developed. Interactions between ADN and MMAN appear to enhance the generation of N2, while the presence of urea reduces the net exothermic heat of reaction due to the endothermic pyrolysis reaction of urea to NH3 and HNCO, followed by the reaction HNCO + H2O → NH3 + CO2.

Ammonium dinitramide (ADN; [NH4]+[N(NO2)2]-) is the most promising oxidizer for use with future green solid and liquid propellants for spacecraft applications. To allow the effective development and use of ADN-based propellants, it is important to understand ADN reaction mechanisms. This work presents a detailed chemical kinetics model for the liquid phase reactions of ADN based on quantum chemical calculations. The thermal corrections, entropies, and heat capacities of chemical species were calculated from the partition function using statistical machinery based on the G4 level of theory. Rate coefficients were also determined to allow the application of transition state theory and variational transition state theory to reactions identified in our previous study. The new model employed herein simulates the thermal decomposition of ADN under specific heating conditions and successfully predicts heats of reaction and the gases that result from decomposition under those conditions. The thermal behaviour predicted from the new model was an excellent match with the experimental behaviour observed from thermal analysis using differential scanning calorimetry and Raman spectroscopy. The new kinetic model reveals the mechanism for the decomposition of ADN.
