Spectro-thermal decomposition study of 1,4-dinitroglycoluril (DINGU)

Advances in science and technology of modern energetic materials: An overview

“…The synthesis of high nitrogen content high energetic materials has been in the focus for the last two decades [30][31][32][33][34][35]. High nitrogen content (HNC) materials form a unique class of novel energetic materials, deriving most of their energy from their very high positive heat of formation rather than from the oxidation of the carbon backbone as is the case with conventional energetic materials.…”

Ab initio and DFT study on 1,4-dinitroglycoluril configurational isomers: cis-DINGU and trans-DINGU

“…Khire and co-workers [13] studied spectro-thermal decomposition of cis-DINGU and they proposed that the thermal decomposition mechanism of cis-DINGU should involve N-NO 2 bond cleavage as the primary step. They also proposed that the bond dissociation energy for N-H bond was involved in the rate determining step.…”

“…In the literature, there are many studies on cis-DINGU including its synthesis [4][5][6], structure determination (X-ray diffraction for cis-DINGU) [11], evaluation of the solid-state formation enthalpy [12], spectro-thermal decomposition [13], mass-spectral fragmentation pathways [14], modelization by molecular mechanics [15], modelization by using AM1 and PM3 methods [16]. However, to the best of our knowledge, there is no study on trans-DINGU (neither any X-ray crystallographic investigation nor computational study for it).…”

Synthesis and Characterization of a Thermally and Hydrolytically Stable Energetic Material based on N‐Nitrourea

“…1,4-Dinitroglycouril (DINGU) (Scheme 1), as an insensitive energetic material, slowly decomposes in boiling water [29,30]. Therefore, a new strategy is required to synthesize new N-nitrourea compounds, in which the carbon atom of urea framework is not easily attacked by water.…”
