Description
Summary:Based on the analysis of a large amount of experimental data, Licht has stated [1] that a high level of performance is usually accompanied by an enhanced sensitivity and that insensitive explosives do not exhibit top performance. This statement might be taken as a rule [1,2,3]. Nevertheless, there are some exceptions to it [2,3] (the opposite run of the corresponding relationship), mainly in pure, technically attractive nitramines [3] and in some highly thermostable polynitroarenes [4]. Only recently, the energy gain from the explosion of energetic materials (i.e. the heat of explosion) in that type of studies has been replaced by their energy content, i.e. by their enthalpy of formation, ΔHform [5]. So far, we have dealt with compounds with nitro groups in the molecule. However, the research in the last two decades has focused on energetic materials, mainly with a high nitrogen content, which is bound in their molecules mostly in another form than the nitro groups.
