The thermal hazard of 2,4‐dinitroanisole (2,4‐DNAN) was evaluated by microcalorimetry methods. The specific heat capacity, melting enthalpy, and the solidification heat of 2,4‐DNAN were determined with a Micro‐DSCIII calorimeter. The thermal decomposition behavior of 2,4‐DNAN at four different heating rates was studied by using a C‐500 type calvet microcalorimeter. The kinetic and thermodynamic parameters were obtained from the analysis of the heat flow data. The critical temperature of thermal explosion ( T b ) and the initial decomposition temperature ( T p0 ) were determined to distinctly evaluate the thermal hazard of 2,4‐DNAN.
