Studies on characterisation and thermal behaviour of 3-amino-5-nitro-1,2,4-triazole and its derivatives.

3-Amino-5-nitro-1,2,4-triazole (ANTA) and its derivatives have been prepared in order to carry out the systematic studies on structural aspects, explosive and thermal behaviour. Thermal studies were carried out for ANTA and 4,6-bis-(3-amino-5-nitro-1H-1,2,4-triazole-1-yl)-5-nitropyrimidine (DANTNP) by thermogravimetry (TG), differential thermal analysis (DTA), differential scanning calorimeter (DSC) and manometric thermal analysis. The results show that (DANTNP) is more thermally stable than ANTA when compared in terms of activation energy.
