Synthesis, Scale-Up Of High Nitrogen Energetic Compounds And Study On The Performance Of High Nitrogen-Based Explosive

The synthesis, scale-up and characterization of three high nitrogen energetic compounds derived from tetrazine and azotetraozolate were reviewed. The high nitrogen-based energetic materials were prepared. The thermal decomposition characteristics and energy performance of these materials were systematically measured. The explosive power of some nitrogen-based energetic materials was also measured and theoretically alalysized.In our lab, the scale-up of the synthesis of 3,6-bis(lH-l,2,3,4-tetrazol-5-yl-amino)-l,2,4,5-tetrazine (BTATz), 3,6-diamino- l,2,4,5-tetrazine-1,4-di-N-oxide (LAX-112) and Triamino-guanidinium azotetrazolate (TAGZT) were studied. The scale-up were performed at the 100g, 40g and 100g scale. 500g BTATz, 300g LAX-112 and 700g TAGZT were synthesized totally. The products obtained were characterized and confirmed by element analysis, Difference Scanning Calorimertry (DSC), IR, ~1H NMR and ~1C NMR spectra. The main influencing factors on the synthesis of these compounds were investigated in detail.The processibility, thermal decomposition characteristics and energy performance of high nitrogen compounds/ADN or AP/B-based materials prepared were investigated. The reactivity of these materials and the compatibility between ingredients in the material were studied. The results show that ADN or AP can improve the reactivity of boron, the high nitrogen compounds/ ADN/B-based co-melting materials show the best reactiveness.The impact sensitivity, friction sensitivity and detonation velocity of these high nitrogen-based energetic materials prepared were tested. The theoretical predictions of explosive power of some nitrogen-based energetic materials was studied by VLW EOS and Kamlet equation (NMQ), and the calculational results were compared with the data obtained in experiment and reported in literature.
