Introduction Dinitroglycoluril (DINGU) is a typical cyclourea nitramine. Its crystal density is 1.94 gcm-3. The detonation velocity corresponding to =1.94 gcm-3 is about 8450 ms-1. Its sensitivity to impact is better than that of cyclotrimethylenetrinitramine. It has the potential for possible use as high explosive from the point of view of the above-mentioned high performance. Its preparation,1-4 properties1-4 and hydrolytic behavior4 have been reported. In the present paper, we report i…
Under linear temperature increase condition, the thermal behavior, mechanism and kinetic parameters of the exothermic decomposition reaction of the title compound have been studied by means of DSC and IR. The initial stage of the mechanism was proposed. The empirical kinetic model function in differential form, apparent activation energy and pre‐exponential constant of the exothermic decomposition reaction are a 0.526, 207.0 kJ·mol?1 and 1018.49s‐1, respectively. The critical temperature of thermal explosion of the compound is 252.87 °C. The values of ΔS≠, ΔH≠ and ΔG≠ of the reaction are 128.4 J·mol‐1.K?1, 218.9 kJ·mol?1 and 152.7 kJ·mol?1, respectively.
