摘要：

5,5'-Azo bis(1-methoxy methylamide tetrazole) (ADMCAT) is a key intermediate preparing high energy compound 5,5'-Azo bis(1-nitroaminotetrazole) (ABNAT). ADMCAT was synthesized from methyl hydrazinecarboxylate and azide cyanide by addition, cyclization and azo reaction. The structure of prepared compound was characterized by IR, 1H-NMR, 13C-NMR, elemental analysis. The ADMCAT single crystal was obtained and analyzed. The thermal stability of 1-methoxy methylamide-1,5-diamino tetrazole (MCDAT) and ADMCAT were tested by differential scanning calorimetry (DSC). The results show that the crystal of ADMCAT belongs to monoclinic system with space group P2(1)/c. The crystallographic parameters are as follows: a=(0.989 5±0.000 8) nm, b= (0.593 4±0.000 5) nm, c= (1.146 7±0.000 9) nm, α= 90°, β= (103.798±0.011)°, γ= 90°, V=(0.653 9±0.000 9) nm3, Z= 2, Dc= 1.586 g∙cm-3, μ= 0.134 mm-1, F(000)= 320. DSC results reveal that MCDAT and ADMCAT have good thermal stability. © 2021, Editorial Board of Journal of Chemical Engineering of Chinese Universities". All right reserved."
