4,5-Dinitro-1-methylimidazole (4,5-MDNI), a low melting point explosive: synthesis and studies on thermal behavior

ABSTRACT

In this work, 4,5-dinitro-1-methylimidazole (4,5-MDNI) was synthesized and characterized. The thermal decomposition performance of 4,5-MDNI was studied by accelerating rate calorimeter (ARC) under adiabatic conditions, and the thermal decomposition reaction order, possible thermal decomposition kinetic model, and self-accelerating decomposition temperature were calculated. The stability of 4,5-MDNI and its compatibility with high-energy explosives (RDX, HMX, CL-20) were studied by differential scanning calorimetry (DSC). The test results show that 4,5-MDNI has a good stability, poor compatibility with HMX, and basically incompatibility with RDX or CL-20.
