其他摘要：N-Nitrodihydroxyethyl dinitrate (DINA) is a commonly used energetic material. In this work, the effect of diethanolamine (DEA) on the thermal stability of DINA was studied. Firstly, the decomposition kinetics of DINA under the influence of DEA was analyzed by applying dynamic differential scanning calorimeter (DSC) experiments. Then, isothermal DSC tests with the “Interruption and re-scanning” method determined that the decomposition reactions of DINA containing 29% DEA consists of four continuous steps: the first step is a n-order reaction, and the last three steps are autocatalytic reactions. The kinetic parameters of the four-step reaction model were calculated by model-fitting method. Finally, the thermal risk parameter like TMR ad was predicted based on the kinetic parameters, which has certain guiding significance for the process production of DINA.
