摘要：
To detailedly understand the non-isothermal thermal decomposition characteristics of N, N-bis-(1(2)H-tetrazol-5-yl)amine (H2BTA), the thermal decomposition characteristics at different heating rates and types of decomposition gas products and their content change for this compound were measured by means of TG-DSC-FTIR-MS and its thermal decomposition mechanism was analyzed. The results show that with the increase of temperature, the thermal decomposition of H2BTA is divided into three successive processes: broking of tetrazole rings of the molecule began to release N2 mainly with the rapture of bond, the further rapture of bond in skeleton and release of N2, and the decomposition of residual skeleton with the expulsion of N2, NH3, HN3 and HCN. The apparent activation energies of the three processes are 187.19, 142.32 and 198.93kJ/mol, respectively. © 2018, Editorial Board of Journal of Explosives & Propellants. All right reserved.
