Synthesis, characterization and thermolysis studies on new derivatives of 2,4,5-trinitroimidazoles: Potential insensitive high energy materials

The crystal structure of 1-methyl-2,4-dinitro-5-iodoimidazole, C4H3IN4O4

“…Recently, these so called "high energy density materials" have attracted renewed attention in conjunction with their favorable detonation performance [4,5]. As a promising candidate, 1-methyl-2,4,5-trinitroimidazole was synthesized by the nitration of 1-methyl-2,4,5-triiodoimidazole [6,7]. The result showed two iodine atoms were substituted by nitro groups, while the position of another iodine could not been con rmed.…”

A theoretical charge density study on nitrogen-rich 4,4′,5,5′-tetranitro-2,2′-bi-1H-imidazole (TNBI) energetic molecule

“…Various nitroimidazole derivatives including 2,4-dinitroimidazole (2,4-DNI), 4,5-dinitroimidazole, 2,4,5-trinitroimidazole, and 1,2,4,5-tetranitroimidazole have been investigated experimentally as well as theoretically [17]. TNBI molecule is belongs to one of this series, which has been synthesized by treating 2,2-bi-1H-imidazole with an excess of sodium nitrate [18,19].…”

Quantum chemical study on nitroimidazole, polynitroimidazole and their methyl derivatives

“…Drop weight impact tests show that 2,4,5-trinitro-imidazole has a much higher impact sensitivity (h 50 ) value (68 cm) than RDX (28 cm), HMX (32 cm), and even higher than 2,4,6-trinitrophenol (picric acid, 64 cm) [13]. Cho et al's preliminary sensitivity tests reveal that 1-methyl-2,4,5-trinitroimidazole is a promising candidate as an insensitive high explosive, with its explosive performances comparable to RDX and with its sensitivity intermediate between RDX and TNT [9,14]. In addition, owing to its low melting point (82 • C), 1-methyl-2,4,5-trinitroimidazole is believed to be an excellent candidate for inclusion in melt-castable explosives, and may lead to increased explosive power.…”
