Accelerated isothermal decomposition behavior derived from the interaction of 3,4-dinitrofurazanfuroxan (DNTF) with amino nitrogen-rich compounds

The mechanism underlying the isothermal decomposition of DNTF in various amino nitrogen-rich compounds was explored in this work. Results showed interactions between DNTF and the hybrid systems of nitrogen-rich molecules containing N[sbnd]H bonds, and these interactions accelerated the decomposition of DNTF. The kinetic parameters of the samples at the pre-decomposition stage were calculated under isothermal conditions, and the results confirmed that the activation energy of the hybrid system was significantly lower than that of the DNTF monosystem. According to FT-IR and HPLC measurements, it was found that the decomposition rate of DNTF in hybrid system was faster than that of AMTZ, and that the furoxan ring broke first, followed by the accelerated decomposition of AMTZ, which also indicated that AMTZ could accelerate the decomposition of DNTF, and they may have promoted each other's decomposition.
