Synthesis, Scale-up and Properties of 3,6-Diamino-1,2,4,5-tetrazine-1,4-dioxide

High-nitrogen energetic compound 3,6-diamino-1,2,4,5-tetrazine-1,4-dioxide(DATZO_2) was synthesized from 3,6-bis(3,5-dimethylpyrazol-1-yl)-1,2-dihydro-1,2,4,5-tetrazine(BDT) by a two-step reaction sequence,with an overall yield of(46.8%) at the 30 g scale.3,6-bis(3,5-dimethylpyrazol-1-yl)-1,2,4,5-tetrazine(BT),which is an important synthesis intermediate,was obtained by using oxygen as oxidizer without N_xO_y.A series of synthesis and recrystallization methods was developed to yield different particle sizes and morphologies,and their sensitivity were tested.The thermal decomposition of DATZO_2 was investigated,kinetic parametes of decomposition and mechanism functions were obtained.
