32个三硝基芳香族炸药分子的原子化能与其撞击感度的关系研究
Relationship of the atomization energy and impact sensitivity of thirty-two trinitro-aromatic-explosives
摘要
Abstract
A calculation of the atomization energy (Ae ) and the ratio of the atomization energy to the to-tal molecular energy Ae /E for trinitro-aromatic explosive molecules using density functional theory indi-cates that there is a nearly linear correlation between the impact sensitivity and the ratio of the atomiza-tion energy to the total molecular energy Ae /E of explosive molecules .A calculation in 32 molecules w hich have similar structure and almost include all of small and middle size trinitro-aromatic-explosives molecules shows that the correlation between the ratio of the atomization energy to the total molecular energy (Ae /E) and the impact sensitivity depends on the structure and activity of the molecules .For more clearer investigation of the relationship we have classified these 32 trinitro-aromatic explosive mole-cules into two groups according to whether it contains α-CH .It is found that there is a linear correlation between the values of Logh50% and the ratio of the atomization energy to the molecular total energy (Ae /E) in the group of compounds that does not containα-CH ,and this relationship is excellent .The rela-tion between the values of Logh50% and the ratio of the atomization energy to the molecular total energy (Ae /E) in the group of compounds that containsα-CH just exists ,and it reaches statistical significance (P=0 .0208<0 .05) .Based on the equation of the correlation we predict the impact sensitivities of eight explosive molecules in this paper .关键词
