Thermal decomposition of ammonium dinitramide and mechanism of anomalous decay of dinitramide salts

Russian Chemical Bulletin, 1999
Thermal decomposition of ammonium dinitramide proceedsvia homolytic rupture of the N−NO2 bond and partially by the proton transfer reaction. The monomolecular decay of the anion to N2O and NO3 − in the solid state at 60 °C occurs with higher rates than those in the melt.

Stabilization of ammonium dinitramide in the liquid phase

Russian Chemical Bulletin, 2000
The kinetics of accumulation of the main products of thermal decomposition of ammonium dinitramide in the melt was investigated. The isotope composition of nitrogen-containing gases evolved by the decomposition of 15NH4N(NO2)2 and NH4 15N(NO2)2 was found.

Role of Additives in the Combustion of Ammonium Dinitramide

Propellants, Explosives, Pyrotechnics, 2014
AbstractThe thermal decomposition behavior and combustion characteristics of mixtures of ammonium dinitramide (ADN) with additives were studied. Micrometer‐sized particles of Al, Fe2O3, TiO2, NiO, Cu(OH)NO3, copper, CuO, and nanometer‐sized particles of aluminum (Alex) and CuO (nano‐CuO) were employed.

Ammonium Dinitramide:  Kinetics and Mechanism of Thermal Decomposition

The Journal of Physical Chemistry A, 1997
Thermal decomposition of ammonium dinitramide (ADN) has been studied by differential scanning calorimetry (DSC) and thermal gravimetry combined with mass spectrometry (TG−MS). ADN decomposes in the range 130−230 °C with an overall heat release of 240 ± 40 kJ mol-1.

Ammonium Dinitramide−Water:  Interaction and Properties

Journal of Chemical & Engineering Data, 2006
The interaction between ammonium dinitramide (ADN) and water was experimentally investigated by determining the solid−liquid phase diagram for the system ADN−water and by measuring its critical relative humidity at 25 °C. Additionally, the density of aqueous ADN solutions of different compositions were measured in the temperature range from (5 to 85 ...
