High energetic materials (HEMs) are chemical substances that possess a large amount of energy for explosives, propellants, and pyrotechnics. Safe treatment of HEMs requires a deep understanding of its chemical and physical properties. In previous studies, the chemical reaction mechanism has been clarified by constructing model with gas-phase and condensed-phase reaction. The model is based on chemical reactions without physical phenomena. The effect of physical phenomena on the chemical reaction behavior has not yet been clarified. The purpose of this study is to analyze the effect of evaporation on the condensed-phase reaction. The evaporation model was incorporated into the existing condensed phase reaction model. Ammonium dinitramide (ADN), which is attracting attention as a next-generation propellant, was selected as the target material. The mass loss behavior of ADN during the condensed-phase reaction process was calculated from the simulation results of the constructed model and compared. As a result, it was clarified that evaporation affects the condensed-phase reaction behavior of ADN by variations in the ADN decomposition species over time, which contributes to the elucidation of the condensed-phase reaction mechanism of ADN.
