“…A more direct connection between df and T may be possible, i.e., fast small-scale turbulent mixing in the reaction zone or a significant increase of heat conductivity in the shock compressed media. These data are close to the results obtained earlier (Kondrikov et al 1973) for a leading reaction of the nitrocompounds burning (Ea = 28 kcal/mole, Z0 = 10 10 -3 1/mole-s). If such a direct connection between d. and T were to exist, the activation energy E3 and pre-exponential factor Z of a leading chemical reaction in the detonation wave can be calculated from the constants of Eq.…”

“…These values are close to the activation energy of the rate-controlling combustion reaction (28 kcal/mole) of a series of aromatic nitro compounds at a pressure of 30 MPa was experimentally obtained earlier [4]. In the first flame of energetic materials whose pyrolysis products are close in nature to HCN, the heat release rate may be determined by the decomposition reaction of NO 2 with an activation energy of 60.1 kcal/mole.…”

“…He suggested that in the case of nitro esters, the rate-controlling reaction at low pressures is the interaction of nitrogen dioxide with formaldehyde or other aldehydes produced by molecular decomposition. According to the results of studies of his follower Kondrikov with coworkers [4], the combustion temperature has a decisive effect on the burning rate of conventional C-nitro compounds at high pressures and that the combustion is adequately described by the Belyaev model with an activation energy of ≈28 kcal/mole, which was assigned to the activation energy of interaction of NO with CO. Fogel'zang, studying the combustion of compounds containing oxidizers of various natures (salts of ammonium with various inorganic oxidizer acids) [5] revealed no correlation between the burning rate and the stability of the salt.…”

For model systems with known kinetics of elementary reactions (CH 3 NO 2 and HN 3 ), temperature ranges are established in which the rate-controlling reactions are the initial endothermic decomposition of the starting material or the subsequent secondary reactions. Heat release in reactions of NO 2 , NO, and N 2 O with various fuels, such as CH 2 O, CO, H 2 , and HCN, is modeled to establish the kinetic parameters and nature of the rate-controlling reactions in gas flames of nitro compounds. It is shown that the activation energy of the heat-release reaction due to the interaction of NO 2 with a hydrocarbon fuel (which is characteristic of the first flame of nitro compounds) is in the range of 29-33 kcal/mole, depending on the type of fuel. According to the calculations performed, the activation energy of the rate-controlling heat-releasing process due to the deoxidation of NO and N 2 O (which is typical of the second flame of nitro compounds) is 43-58 kcal/mole. In the range of high pressures, where the flames merge, the kinetic parameters of heat release are determined by the reactions of the most reactive nitrogen oxide NO 2 .

“…In the previous study, the flame temperature of mDNB reached to 1918 K in pressurized air, which is higher than those of other dinitro compounds such as 1,5-dinitoronapthtalene and 2,4-dinitrotoluene [20] . In this study, the combustion of TA/mDNB with ammonium nitrate was terminated at 1, 2, and 3 MPa of nitrogen.…”

Abstract. The electrostatic interactions between gas generating agent and organic electron withdrawing additives were studied to understand how the interaction affects the reactions of their thermal behavior. To explore the electronic interaction and its effect, the thermal behavior of a mixture of dinitrobenzene isomers [p-dinitrobenzene (pDNB) and m-dinitrobenzene (mDNB)] and 1,2,4-triazole (TA) was analyzed. Density functional calculations and electron density analysis proved that both pDNB and mDNB in a 1:1 ratio withdraw electrons from TA. The analysis of pyrolysis behavior showed that TA and dinitrobenzene
