Description

Technical Field

[0002] In the field of energetic materials research, scientists have been committed to designing and synthesizing compounds with both high energy density and high stability. The realization of this goal is crucial to the development of energetic materials with excellent detonation performance. Ideal energetic materials should have high formation enthalpy and high density, which together ensure efficient energy release in practical applications. At the same time, in order to ensure the safety and reliability of the material in various environments, the molecular structure of the compound should also have good insensitivity and excellent thermal stability by fine-tuning the molecular structure of the compound.

[0003] A fused ring compound refers to a compound containing two or more juxtaposed ring structures. Compared with their monocyclic or simple polycyclic homologues, such compounds generally exhibit more significant chemical stability, higher density and more chemical modification sites. In nature, a variety of fused ring compounds with important biological activities have been discovered, including heterocyclic fused ring compounds. In recent years, with the continuous advancement of chemical synthesis technology, the number of artificially synthesized nitrogen-containing fused ring compounds has also continued to increase. There are various synthesis methods for these compounds, including but not limited to intramolecular cyclization reactions, such as aromatic nucleophilic substitution reactions, intracyclic affinity substitution reactions, acyl nucleophilic substitution reactions, etc. However, the difficulty of constructing fused ring skeletons is generally greater, which leads to relatively few types of such compounds.

[0174] The bistriazolotriazine fused ring nitrogen-rich compound energetic ion salt 1-2 prepared in Example 5 is applied to a detonator.

[0175] The specific operation is: carefully inject 150g of melted TNT into the detonator, then quickly add 250g of bistriazolotriazine fused ring nitrogen-rich compound energetic ion salt 1-2 that has been ground into fine powder into the detonator, stir as evenly as possible, cool to room temperature, and then conduct a detonation test. The results are as follows Figures 8 to 11 shown.

[0177] The bistriazolotriazine fused ring nitrogen-rich compound energetic ion salt 1-1 prepared in Example 1 is used as an energetic material.

[0178] The specific operations are:

[0179] 100g of TNT ground into powder and 100g of bistriazolotriazine fused ring nitrogen-rich compound energetic ion salt 1-1 ground into powder were mixed evenly, heated to 90°C, kept warm for 30 minutes, and then 150g of the paste mixture was carefully injected into a plastic tube. The detonation velocity was measured to be 8090m / s.

[0180] 4) Detonation performance test

[0181] The specific operation steps are: the results of compounds 1, 1-1, 2 and 2-2 are shown in Table 1.

[0183]

[0184] From the analysis in Table 1, it can be seen that compound 2 is better than compound 1 in thermal stability (T d ), density (ρ) and detonation performance. After the introduction of perchlorate ions, the performance of compounds 1-1 and 2-1 were significantly improved, with thermal decomposition temperatures of 325 and 309 °C, respectively, and the density of 2-1 even reaching 1.89 g cm -3 , and their detonation speed and pressure are 8520m s -1 and 32.53GPa, which is superior to TNT and TATB and is a potential energetic material.
