摘要
Abstract
In this research, an eco-friendly, energetic Bi(III) complex of 2,6-diamino-3,5-dinitropyridine-1-oxide (ANPyO) was synthesized and its structure was characterized by FTIR, elemental analyses and XPS measurements.Based on the results of structure analyses, we speculate that chemical constitution of the complex can be deduced as Bi(C5H4N5O5)3, and the ratio of Bi(III) and ANPyO is 1∶3.The central Bi(III) ion contributes its six empty orbitals to accommodate the long pair electrons from the imine N atoms and N→O O atoms from three different deprotonated ANPyO molecules.Impact sensitivity, friction sensitivity and shock wave sensitivity of Bi(III) complex of ANPyO are 220 cm, 36 kg and 5.8 mm, respectively.The thermal decomposition behavior of Bi(III) complex of ANPyO was studied by TG-DTG and DSC measurements.The thermal decomposition of the complex consists of one endothermic (320.6 ℃) and one exothermic (346.5 ℃) peaks in the temperature range of 50～450 ℃ with 31.2％ residue.Meanwhile, the catalytic performance of the complex on the thermal decomposition of ammonium perchlorate (AP) was analyzed by TG-DTG and DSC analyses, the apparent activation energy and pre-exponential factor of pure AP and AP mixture in the low temperature decomposition stage and high temperature decomposition stage were calculated by Kissinger's formula as well.The results show that Bi(III) complex of ANPyO makes the exothermic peak temperatures and activation energy values of high temperature decomposition stage and low temperature decomposition stage for AP decrease by 63.6 ℃, 63.1 ℃, 23.1 kJ/mol and 61.5 kJ/mol, respectively, the apparent exothermic quantity for AP increase by 339.3 J/g, revealing that the complex has good catalytic effects on the thermal decomposition of AP.关键词
