摘要
为研究含能材料热分解过程的瞬间性和安全性,运用电子自旋共振技术(ESR)检测了HMX,CL-20和DNTF的自由基,得到了它们在相同的光照强度和时间间隔中,各体系的电子自旋共振谱图。结果表明,DNTF在没有光照的情况下即会产生自由基,HMX和CL-20光照一定时间后有自由基产生。随着光照时间的延长,自由基逐渐增多,DNTF的自由基信号最强。
In order to investigate the safety and instantanity of thermal decomposition process of energetic material,the free radicals of 1, 3, 5, 7-tetranitro-1, 3, 5, 7-tetraazacyclooctane （HMX）, hexanitrohexaaz-aisowurzitane （HNIW,CL-20） and 3,4-dinitrofurazanfuroxan （DNTF） were measured by Electron Spin Resonance （ESR）. In the same light intensity and time-interval, the ESR spectrometris of the three compounds were obtained, The results show that the free radical signal of DNTF appeared without light, however, the free radical signal of CL-20 and HMX appeared after receiveing some energy from the light, The quantites of their free radical was increased with the time expanded under the light and the signal of DNTF is the strongest among the three energetic materiais.
