Thermal Decomposition Mechanism of 3,3'-diamino -4, 4' -azoxyfurazan

摘要

The thermal decomposition mechanism of 3, 3'-diamino-4, 4' -azoxyfurazan (DAOAF) was investigated by several techniques such as TG-FTIR, pyrolysis-GC/MS, pyrolysis-synchrotron radiation and theoretical calculations. The results indicate that the decomposition gas products of DAOAF mainly include HNCO, HCN, N2, CO2, N2O, NO, NCCN and NCNCO. The decomposition begins with the breaking of N-O bond in the furazan ring and the C-N bond connecting with azoxy which is supported by theoretical calculation results. Based on the experiment and theoretical calculation results, the thermal decomposition mechanism of DAOAF was proposed.
