Abstract and subjects
The synthesis of 1-nitroguanyl-3-nitro-5-amino-1,2,4-triazole (ANTA-NQ) (1) with good yield and high purity is described. DSC analysis showed that the material displays good thermal stability. An X-ray crystallographic analysis confirms the structure of this material, as well as displays intramolecular hydrogen bonding. A gas pycnometry density for this material was measured to be 1.79 g?cm-3. The heat of formation of this material was also measured. These data, along with the molecular formula were used as inputs to calculate the detonation velocity and detonation pressure using the Cheetah thermochemical code. The sensitivity of this material towards impact, spark and friction was also measured, as well as its vacuum thermal stability. The 3-azido derivative 2 was also prepared and its properties are described as well. The above data show that (ANTA-NQ) may be a high performing material with low sensitivity and good thermal stability.
