“…During our investigations, we found that triaminoguanidinium azotetrazolate (TAGzT), triaminoguanidine nitrate (TAGN) and nitroguanidine (NQ) were reported previously as high nitrogen fuels/monopropellants ,. The compounds were synthesized with expensive starting precursors, vigorous conditions and multi‐step synthetic procedures.…”

The nitrogenous salts of 4-nitramino-1,2,4-triazole (4-NRTZ, 2), namely ammonium-4-nitramino-1,2,4-triazolate (Amm-4-NRTZ, 3), hydrazinium-4-nitramino-1,2,4-triazolate (Hy-4-NRTZ, 4) and hydroxylammonium-4-nitramino-1,2,4-triazolate (HyAm-4-NRTZ, 5) were synthesized, characterized by spectroscopic (FTIR, FT-Raman, NMR) methods and their structures were confirmed by single-crystal X-ray diffraction technique. The salts (3-5) prepared in good yields showed good thermal stabilities and positive heat of formation. Ordered packing in lattice proved the better insensitivity of 3 & 5 towards IS, FS and ESD. Compounds 2 & 5 were further studied for its pressure generating capability inside a constant volume combustion chamber. Pressure-time (P-t) traces as well as dp/dt analysis revealed compound 5 has good gas generating capability. Theoretical predictions on the ballistic parameters in comparison with known compounds substantiate the potential of 5 as a strong candidate in propellant/gas generating composite materials.

This paper reviews the production, synthesis, crystallography, particle morphology and spectroscopy of the insensitive high explosive nitroguanidine, (NGu, CH4N4O2), CAS‐No: [556‐88‐7] and its isotopologues [2D4]‐NGu and [15N4]‐NGu]. When compared with standard insensitive high explosives such as 1,3,5‐triamino‐2,4,6‐trinitrobenzene (TATB), 1,1‐diamino‐2,2‐dinitroethylene (FOX‐7) and N‐guanylurea dinitramide (FOX‐12), Nitroguanidine proves to be the least sensitive. The review gives 170 references to the public domain. For Part II see ref. [1].
