title: Synthesis and characterization of 3,6-bis(1H-1,2,3,4-tetrazol-5-ylamino)-1,2,4,5-tetrazine (BTATz): novel high-nitrogen content insensitive high energy material.
abstract: This paper reports the synthesis, characterization and thermolysis studies of 3,6-bis(1H-1,2,3,4-tetrazol-5-ylamino)-1,2,4,5-tetrazine (BTATz) and 3-(1H-1,2,3,4-tetrazol-5-ylamino)-6-(3,5-dimethyl-pyrazol-1-yl)-s-tetrazine monohydrate (TADPTz). The synthesized BTATz and TADPTz have been characterized by spectroscopic techniques and the data obtained confirm their structure. TGA and DSC results suggested that BTATz decomposes in the range 265-350 degrees C and TADPTz in the range 245-275 degrees C respectively. The calculated energy of activation of BTATz and TADPTz is 212.69 and 257.29kJ/mol respectively. The experimentally determined DeltaH(f) value matches with theoretically computed heat of explosion. The computed volume of gases indicates that they can find application in gas generating compositions.
