Synthesis and Characterization of Energetic Intermediate 5-Hydrazinotetrazole

ZHU Ya-hong,SHENG Di-lun,CHEN Li-kui,MA Feng-e(Shaanxi Applied Physicochemical Research Institute,Xi'an 710061,China)  
5-Hydrazinotetrazole was synthesized with 5,5'-azotetrazolate as starting material by the acidizing of hydrochloric acid and recrystallizing of sodium acetate processes.Its structure was characterized by Fourier transform infrared,melting point and elemental analyses.The key factors affecting acidizing and recrystallizing of synthesis were discussed.The results show that the mass fraction of material used during acidizing is 10% for 5,5'-azotetrazolate solution and 10%-15% for hydrochloric acid solution.The yield of 5-hydrazinotetrazole is 55%-60%,and melting point is 196-198.9℃.
