Abstract:

通过合理假设,从谢苗诺夫(Semenov)热爆炸理论和8个非等温动力学方程,导出了估算含能材料(EMs)热爆炸临界温度(Tb)的2个通式和它们的6个派生式。从EMs的非等温DSC曲线可获得DSC曲线偏离基线的起始温度(T0)、onset温度(Tei)和放热分解反应的动力学参数。由方程T0iorei=T00ore0+a1βi+a2βi2+…+aL-2βiL-2,i=1,2,…,L可得到T00和Te0值,随后用6个派生式可计算Tb值。对1,4,5,8-四硝基-1,4,5,8-四氮杂双呋咱[3,4-c:3′,4′-h]十氢化萘,1,4,5,8-四氮杂双呋咱[3,4-c:3′,4′-h]十氢化萘,1,3,4-三硝基咪唑烷酮[4,5-b]呋咱[3,4-e]哌嗪,咪唑烷酮[4,5-b]呋咱[3,4-e]哌嗪,1,3,4,8-四硝基咪唑烷酮[4,5-b]呋咱[3,4-e]哌嗪,1,4,5,8-四硝基-1,4,5,8-四氮杂萘呋咱[3,4-b]十氢化萘,1,3,5-三硝基-1,3,5-三氮杂呋咱[3,4-f]环庚烷,由6个派生式所得的Tb值甚接近。
