Abstract
The specific heat capacity (Cp) values of four energetic compounds, 3-nitro-1,2,4-triazol-5-one (NTO), carbohydrazide(CHZ), 2,4-dinitrophenol (DNP) and picric acid (PA), were determined by differential scanning calorimeter (DSC). The least square method is applied to treat experimental data. In the range of 340-410 K, the Cp versus T relationship of NTO and CHZ can be expressed as a simple equation: CP=a+bT. In the range of 330-360K, the Cp versus T relationship of DNP and PA can be expressed as a cubic equation: Cp=a+bT+cT2+dT3. The R-Squares(COD) of measured results of NTO, CHZ, DNP and PA, are 0.9591,0.9730,0.9968 and 0.9972, respectively.关键词
