Thermal hazard assessment of TNT and DNAN under adiabatic condition by using accelerating rate calorimeter (ARC)

The thermal decomposition behaviors of 2,4,6-Trinitrotoluene (TNT) and 1-methoxy-2,4-dinitro-benzene (DNAN) were studied by using a NETSCH company accelerating rate calorimetry. Hazard indicators such as onset temperature, adiabatic temperature rise, initial self-heat temperature, maximum self-heating rate, and time-to-maximum temperature rise rate have been determined directly. The kinetic parameters, such as the activation energy ( E a ) and the pre-exponential factor ( A ) were studied from the measured self-heating rate data by assuming order reaction.
