Accurate values of physical properties of munitions compounds are crucial for understanding their environmental distribution, and for development of potential environmental treatment processes. Informed decisions on development of waste treatment technologies can be made by close examination of physical properties of munitions compounds. Physicochemical properties such as melting point and vapor pressure are important in understanding a munitions dispersion and fate within the environment. The physicochemical properties (both model predictions and experimental data) of 15 energetic materials were collected from literature. The energetic materials considered during this study are dinitroanisole (DNAN), n-methyl-p-nitroaniline (MNA), nitro-triazolene (NTO), triaminotrinitrobenzene (TATB), cyclotetramethylene-tetranitramine (HMX), cyclotrimethylenetrinitramine (RDX), trinitrotoluene (TNT), Chinalake-20 (CL-20), Diamino-Dinitroethylene (DADE), 1,3,3-Trinitroazetidine (TNAZ), Pentaerythritol tetranitrate (PETN), 2,4-Dinitrophenol (DNP), 1-Methyl-2,4,5-trinitroimidazole (MTNI), Triacetone Triperoxide (TATP), and 2,4,6-trinitrophenyl-N-methylnitramine (TETRYL). Results of model predictions are compared with available experimental vapor pressure and meting point data, and the data gaps are identified.
