摘要
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T0ior ei=T00 or e0+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。
Two general expressions and their six derived formulae for estimating the critical temperature（Tb） of thermal explosion for energetic materials（EMs） are derived from the Semenov′s thermal explosion theory and eight non-isothermal kinetic equations,using reasonable hypothesis.The initial temperature（T0i） at which DSC curve deviates from the baseline,the onset temperature（Tei）,the kinetic parameters of exothermic decomposition reaction can be obtained from the non-isothermal DSC curve of EMs.The values of T00 and Te0 was obtained from the equation T0i or ei=T00 or e0＋a1βi＋a2βi^2＋…＋aL-2βi^L-2,i=1,2,…,L and then the values of Tb was calculated by the six derived formulae.The Tb results obtained with the six derived formulae for 1,4,5,8-tertanitro-1,4,5,8-tetraazadifurazano[3,4-c：3′,4′-h] decalin and its parent compound,1,3,4-trinitro-imidazolonone furazano piperazine and its parent compound,1,3,4,8-tetranitro-imidazolinone furazano piperazine,1,4,5,8-tetranitro-1,4,5,8-tetrazafurazano decali n and 1,3,5-trinitro-1,3,5-triazafurazano cycloheptane approximate well to each other.
