Ammonium salts of 1,2,4-triazole-3-one and 1,2,4-triazolidine-3,5-dione were synthesised and their properties were evaluated.
The boiling point of 1,2,4-triazole-3-one allowed direct reaction with liquid ammonia.
Elemental analysis showed that nitrogen content of the ammonium salts increased, as expected, which is favourable for gas generating agents.
FT-IR spectra indicated that the framework structures were conserved during the reaction.
However, ammonia gas was released from 1,2,4-triazole-3-one salts at room temperature, while 1,2,4-triazolidine-3,5-dione maintained its composition.
The thermal decomposition behaviour of 1,2,4-triazolidine-3,5-dione salt showed that ammonium gases evolved at 85℃.
Sensitivity tests were carried out and burning rates of the mixtures with ammonium nitrate and CuO were measured to understand the properties of azole-ammonium salts.
