Synthesis and characterization of 5-(trifluoromethyl)tetrazol-based energetic salts

Two types of 5-trifluoromethyl tetrazole-based energetic salts were successfully synthesized from trifluoroacetamide and sodium azide. The synthetic approach is characterized by its simplicity and safety. The X-ray diffraction analysis reveals the presence of both intermolecular and intramolecular hydrogen bonding within the crystal lattice of energetic salts. The synthesized compound 4 demonstrated notable physical properties, including high densities (1.64 g cm^-3), great thermal stability (with decomposition temperatures of 167 °C), and excellent insensitivity (impact sensitivity exceeding 40 J). These attributes suggest that the compound 4 possess promising energetic performance and is potential candidates for use as insensitive high-energy materials.

期刊介绍： The Journal of Fluorine Chemistry contains reviews, original papers and short communications. The journal covers all aspects of pure and applied research on the chemistry as well as on the applications of fluorine, and of compounds or materials where fluorine exercises significant effects. This can include all chemistry research areas (inorganic, organic, organometallic, macromolecular and physical chemistry) but also includes papers on biological/biochemical related aspects of Fluorine chemistry as well as medicinal, agrochemical and pharmacological research. The Journal of Fluorine Chemistry also publishes environmental and industrial papers dealing with aspects of Fluorine chemistry on energy and material sciences. Preparative and physico-chemical investigations as well as theoretical, structural and mechanistic aspects are covered. The Journal, however, does not accept work of purely routine nature. For reviews and special issues on particular topics of fluorine chemistry or from selected symposia, please contact the Regional Editors for further details.
