Review of the Essential Characteristics of 2,4-Dinitroanisole

With the development of weapons and ammunition to achieve more powerful and safer functional systems, 2,4-dinitroanisole (DNAN), used as an insensitive melt-cast matrix explosive, has received widespread attention. Various countries have conducted significant research and developed a series of DNAN-based explosive formulations in recent years. However, some inherent limitations of DNAN have enormously restricted its comprehensive application in weapons. In this paper, the progress of DNAN research in recent years is systematically reviewed from the aspects of its essential characteristics, such as physical properties (melting point, shrinkage, irreversible expansion, solubility, and mechanical properties), sensitivity and safety, stability, compatibility, and oxygen balance and energy. The advantages and disadvantages of DNAN are analyzed, and methods to solve these limitations are described. Furthermore, several important directions to be studied in future research are highlighted, including the study of DNAN binary eutectic mixtures mechanisms, control of crystal transformation, and improvements in mechanical properties.

Investigation on Irreversible Expansion of 1,3,5-Triamino-2,4,6-trinitrobenzene Cylinder

In this study, the irreversible expansion of TATB cylinder is investigated. No evident variation of the lattice parameters is observed on TATB crystal. The density of TATB powder decreases by only about 0.02% after it suffered from thermal cycling process at the range from -54 C to 74 C, while the density of TATB cylinder decreases by about 1.0%. It is suggested that the density variation of TATB powder has little contribution to the density decrease of TATB cylinder. Therefore, the increasing interstices between TATB powder originated from the thermal cycling should be responsible to the irreversible expansion of TATB cylinder.
