Novel insensitive energetic-cocrystal-based BTO with good comprehensive properties

Abstract

Combining a layer construction strategy with cocrystallization techniques, we designed and prepared an unusual energetic cocrystal, which confirmed by single-crystal X-ray diffraction.

Series of AzTO-Based Energetic Materials: Effect of Different π–π Stacking Modes on Their Thermal Stability and Sensitivity

“…In general, energetic salts have some inherent characteristics of the parent molecule. However, they also show distinct characteristics, such as stacking, stability, and insensitivity, because of the combination of anions and cations. − Cocrystallization is also an uncomplicated and effective method to synthesize insensitive energetic materials and amend and optimize other properties of high-energy materials. − Therefore, when synthesizing the next-generation high-energy materials, we must not only pursue the design of novel molecules but also concentrate with the association of physics, chemistry, crystallography, and structure.…”

Preparation and characteristics of a novel PETN/TKX-50 co-crystal by a solvent/non-solvent method

“…In recent years, quite a lot of energetic cocrystals have been prepared and excellent properties have been obtained. [17][18][19][20][21][22][23] J. P. Shen et al prepared a kind of new cocrystal composed of HMX and TATB by the solvent/nonsolvent method at room temperature and the impact sensitivity of the co-crystal explosive was relatively insensitive in contrast to HMX. 17 Bolton et al 18 prepared a kind of co-crystal with a 2 : 1 molar ratio of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12hexaazaiso-wurtzitane (CL-20) and 1,3,5,7-tetranitro-1,3,5,7tetrazacy-clooctane (HMX).…”

Energetic Cocrystal, Ionic Salt, and Coordination Polymer of a Perchlorate Free High Energy Density Oxidizer: Influence of pKa Modulation on Their Formation

“…In the development of ECC, energetic coformers mainly referred to traditionally used explosives such as HMX, 1-methyl-2,4,6-trinitrobenzene (TNT), 1-methyl-3,4,5-trinitropyrazole (MTNP), and 1-methyl-3,5-dinitro-1,2,4-triazole (MDNT). − Nowadays, some other promising materials were developed for CL-20 based ECCs, such as the interesting melt-castable energetic cocrystal based on 3,4-diaminofurazan (DAF) . In recent years, the research direction of ECCs turned into other nitrogen-rich heterocycles, such as 5,5′-dinitro-2 H ,2 H ′-3,3′-bi-1,2,4-triazole (DNBT), 3,6-dinitropyrazole­[4,3- c ]-pyrazole (DNPP), 3-nitro-1,2,4-triazol-5-one (NTO), ethylenedinitramine (EDNA), 3,6-bis­(1 H -1,2,3,4-tetrazol-5-ylamino) (BTATz), 3,5-dimethylpyrazol-1-yl-substituted-1,2,4,5-tetrazine (BPT), and 1 H ,1 H ′-5,5′-bistetrazole-1,1′-diolate (BTO). − Recently, cocrystals of AP with nonenergetic compounds like different types of crown ethers were prepared through the solvent/antisolvent method . To the best of our knowledge, the energetic cocrystals via perchlorate-free oxidizers have not been reported yet.…”
