Based on the organocatalytic reaction of enamine azide addition of 2,4,6-triazido-1,3,5-triazine to acetylacetone acetoacetic ester, we synthesized a series of previously unknown mono-, di-, and tri(1,2,3-triazolyl)-substituted-1,3,5-triazines that additionally carried carbonyl, ester, and azide groups. The structure of the obtained compounds was proved by NMR (¹H, ¹³C) and IR spectroscopy, and the composition was confirmed by elemental analysis. With the aid of differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) coupled to mass spectrometry (TG-MS), we obtained data on the thermal behavior and decomposition mechanism for these compounds. We demonstrated that di(1,2,3-triazolyl)-substituted 1,3,5-triazines have an increased thermal stability and have higher values of decomposition onset temperature (220–250 °C) in comparison with tri(1,2,3-triazolyl)-substituted 1,3,5-triazines (180 °C and 160 °C, respectively).

基于 2,4,6-三氮杂-1,3,5-三嗪与乙酰丙酮乙酰乙酸酯的烯胺叠氮加成有机催化反应，我们合成了一系列之前未知的单-、二-和三(1,2,3-三唑基)-取代的-1,3,5-三嗪，这些化合物额外带有羰基、酯基和叠氮基团。核磁共振（1H、13C）和红外光谱证明了所获化合物的结构，元素分析确认了其成分。借助差示扫描量热法（DSC）和热重分析法（TGA）耦合质谱法（TG-MS），我们获得了这些化合物的热行为和分解机理数据。我们发现，与三(1,2,3-三唑基)取代的 1,3,5 三嗪（分别为 180 ℃ 和 160 ℃）相比，二(1,2,3-三唑基)取代的 1,3,5 三嗪具有更高的热稳定性和更高的分解起始温度（220-250 ℃）。

In this study, a high-nitrogen insensitive energetic material, 2-amino-4,5-bis(tetrazole-5-yl)-1,2,3-triazole (H₂ABTT), was successfully synthesized by introducing the N-amino group on the 1,2,3-triazole ring. This compound exhibits excellent properties in many aspects. Compared to 4,5-bis(tetrazol-5-yl)-1,2,3-triazole (H₃BTT), which has a decomposition temperature (T_d) of 277 ^oC, nitrogen content of 75.11 %, density of 1.69 g cm⁻³, a detonation velocity of 8630 m s⁻¹, a detonation pressure of 26.3 GPa, an impact sensitivity (IS) of 2 J, and a friction sensitivity (FS) of 240 N, H₂ABTT exhibits higher thermal stability of T_d:303 ^oC, higher nitrogen content of N%:76.35 %, higher density of 1.86 g cm⁻³, more desirable detonation properties (detonation pressure Dv: 9185 m s⁻¹; detonation pressure p: 31.7 GPa), and lower mechanical sensitivities (IS > 100 J; FS > 360 N). Furthermore, H₂ABTT outperforms insensitive explosive TATB (Dv = 8179 m s⁻¹; p = 30.5 GPa; IS = 50 J; FS > 360 N) in some properties, making it a potential high-performance insensitive explosive. Besides, energetic salts 4–6 were successfully synthesized based on H₂ABTT. The calculated results show that some of these salts even possess higher detonation performance compared to H₂ABTT.

本研究通过在 1,2,3- 三唑环上引入 N-氨基，成功合成了一种高氮不敏感高能材料--2-氨基-4,5-双（四唑-5-基）-1,2,3-三唑（H2ABTT）。该化合物在许多方面都表现出优异的性能。与 4,5-双（四唑-5-基）-1,2,3-三唑（H3BTT）相比，其分解温度（Td）为 277 oC，含氮量为 75.11 %，密度为 1.69 g cm-3，爆速为 8630 m s-1，爆压为 26.H2ABTT 具有更高的热稳定性（Td：303 oC）、更高的氮含量（N%：76.35 %）、更高的密度（1.86 g cm-3）、更理想的起爆特性（起爆压力 Dv：9185 m s-1；起爆压力 p：31.7 GPa）和更低的机械敏感性（IS > 100 J；FS > 360 N）。此外，H2ABTT 在某些特性上优于不敏感炸药 TATB（Dv = 8179 m s-1；p = 30.5 GPa；IS = 50 J；FS > 360 N），使其成为一种潜在的高性能不敏感炸药。此外，基于 H2ABTT 成功合成了高能盐 4-6。计算结果表明，与 H2ABTT 相比，其中一些盐甚至具有更高的引爆性能。

Nitroamino is an ideal high-energy group for constructing energetic compounds. The skeletal isomerization of nitroamino to nitroimino forms intramolecular HBs, thus resulting in better density, thermal stability and sensitivity. However, it is difficult to find nitroamino and nitroimino in the same environment for comparative analysis. A new compound, 5-Nitroamino-8-nitroimino-1,4-dihydropyrazino [2,3-d]pyridazine-2,3-dione (3), was designed and synthesized. The symmetric skeleton of pyrazino [2,3-d]pyridazine provides the same environment for both nitroamino and nitroimino groups. By using a variety of computational and graphical methods, a theoretical support for nitroamino-based energetic materials was produced by thoroughly examining the influence between nitroamino and nitroimino.

硝基氨基是构建含能化合物的理想高能基团。硝基氨基到硝基氨基的骨架异构化形成分子内HBs，从而产生更好的密度、热稳定性和灵敏度。然而，很难在同一环境中找到硝基氨基和硝基亚胺进行比较分析。设计合成了新的化合物5-硝基氨基-8-硝基氨基-1,4-二氢吡嗪[2,3-d]吡嗪-2,3-二酮(3)。pyrazino [2,3-d]吡嗪的对称骨架为硝基氨基和硝基氨基提供了相同的环境。通过多种计算和图解方法，深入研究了硝基氨基和硝基氨基之间的影响，为硝基氨基基含能材料的研究提供了理论支持。

To overcome the agglomeration and insufficient combustion of nano-boron (n-B) powders, this study successfully prepared two novel types of boron-based nanocomposites using the acoustic resonance technology, namely high-substitute nitrochitosan/nano-boron (NCh-B) with ratios of 1:3, 1:5, 1:7, and 1:9 and nitrochitosan/nano-boron powder/nano-titanium (NCh-B-Ti) with Ti contents of 5 wt%, 10 wt%, 15 wt%, and 20 wt%. The structural morphologies, laser ignition, and combustion properties of the composites were systematically investigated. The results suggest that the addition of NCh can significantly improve the dispersion of n-B. NCh-B exhibited a higher combustion performance than n-B, as evidenced by their ignition delay and flame areas. When the laser power density was 81 W, NCh-B5-Ti15% exhibited a combustion time and an ignition delay of 240 ms and 5.5 ms respectively, which were higher and lower than those of NCh-B5 (199 ms and 17 ms, respectively). Furthermore, NCh-B5-Ti15% displayed a lower ignition delay than both n-B powders (12 ms) and NCh-B (11 ms), as well as brighter flames and a larger combustion area. Therefore, the addition of n-Ti can promote the combustion of the n-B powders, with the combustion products of NCh-B-Ti including H3BO3, B2O3, TiB2, and TiO. This study provides a new method for improving the ignition performance and combustion efficiency of n-B powders.

为了克服纳米硼(n-B)粉团聚和燃烧不充分的问题，本研究利用声共振技术成功制备了两种新型的硼基纳米复合材料，即高替代亚硝基壳聚糖/纳米硼(NCh-B)(比例分别为1:3、1:5、1:7和1:9)和亚硝基壳聚糖/纳米硼粉/纳米钛(NCh-B-Ti)(钛含量分别为5wt %、10wt %、15wt %和20wt %)。系统地研究了复合材料的结构形态、激光点火性能和燃烧性能。结果表明，NCh的加入能显著改善n-B的色散。NCh-B的燃烧性能优于n-B，其燃烧延迟和火焰面积均优于n-B。当激光功率密度为81 W时，NCh-B5- ti15%的燃烧时间和点火延迟分别为240 ms和5.5 ms，高于NCh-B5 (199 ms和17 ms)。NCh-B5-Ti15%比n-B粉末(12 ms)和NCh-B粉末(11 ms)具有更低的点火延迟，火焰更亮，燃烧面积更大。因此，n-Ti的加入可以促进n-B粉末的燃烧，NCh-B-Ti的燃烧产物包括H3BO3、B2O3、TiB2和TiO。该研究为提高n-B粉末的点火性能和燃烧效率提供了一种新的方法。

The composition of a pasty propellant for small-sized space engines has been proposed. For this propellant, a research of the burning process was carried out. This research included the determination of the burning rate law, the characteristics of the agglomeration process, and the properties of the surface layer. The presence of an intermediate structure, a skeleton layer, during the burning of such propellants, and the nature of the influence of pressure, additives, and the size of oxidizer particles on this structure, have been established. The determining influence of this structure on the burning process is shown. Composition solutions that provide control over the burning rate law of such propellants are determined. These solutions make it possible to change the absolute value of the burning rate, as well as its dependence on pressure. Regularities of the agglomeration process have been established. These regularities are associated with the features of the formation of the skeleton layer, which depend on the structure of the propellant, pressure, and the presence of additives.

提出了一种用于小型航天发动机的糊状推进剂的组成。对该推进剂的燃烧过程进行了研究。本研究包括燃烧速率规律的确定、团聚过程的特点以及表面层的性质。在这类推进剂燃烧过程中，存在一种中间结构，即骨架层，以及压力、添加剂和氧化剂颗粒大小对这种结构的影响的性质已经确定。说明了这种结构对燃烧过程的决定性影响。确定了控制这类推进剂燃速规律的组成溶液。这些解决方案可以改变燃烧速率的绝对值，以及它对压力的依赖。建立了团聚过程的规律。这些规律与骨架层形成的特征有关，这取决于推进剂的结构、压力和添加剂的存在。
