Abstract
New energetic salts of 1,2,4-triazole; 3,4,5-triamino-1,2,4-triazole and of 4-amino 1,2,4-triazole were synthesized, characterized and their thermal and safety properties evaluated as possible new propellant ingredients. Energetic anions, including the nitrate anion, NO , the perchlorate anion, ClO , & the dinitramide anion, N(NO ) , were paired with the protonated heterocycles through facile, high yield synthetic routes to give crystalline, energetic salts. Using such a heterocycle system, either 1,2,4-triazole; 3,4,5-triamino-1,2,4-triazole or 4-amino 1,2,4-triazole, a new family of salts were synthesized through the direct reaction of the heterocycle with the corresponding acid form of the desired anion. These reactions were carried out in commonly available polar solvents, and at ambient temperatures, to give high purity, high yield products. All of the salts which were synthesized, were put through thermal stability tests and through impact testing, to reveal a robust family of new insensitive materials, suitable as new energetic propellant ingredients.
