Synthesis of bis(2-methyl-3,5-dinitrophenyl)diazene N-oxide from 2,4,6-trinitrotoluene

摘要

Bis(2-methyl-3,5-dinitrophenyl)diazene N-oxide was obtained in a two-step reaction starting with TNT. The reduction of TNT was conducted using iron powder and acetic acid. In next step, 2ADNT was oxidized with performic acid solution. The final product was purified and analyzed by using the multinuclear NMR spectroscopy (~1H, ~13C). The thermal properties and stability were determined by simultaneous DTAITG techniques and were compared to the properties of commonly known energetic nitroaromatic compounds. Bis(2-methyl-3,5-dinitrophenyl)diazene N-oxide undergoes exothermic decomposition at 282°C. Furthermore, the heat of combustion was measured for the obtained compound and the enthalpy of formation was determined. The theoretical parameters of detonation were also calculated using a thermochemical code.
