| Abstract: | The continuous specific heat capacities at constant pressure (Cp) of energetic materials of mono-substituted potassium (K1TNPG), di-substituted (K2TNPG) and tri-substituted (K3TNPG) trinitrophloroglucinate were measured by differential scanning calorimeter (DSC) method. The change of enthalpy and entropy were calculated at an interval of 5 ℃ in the range of 50-100 ℃. The least square method is applied to treat experimental data. The temperature dependence of Cp was determined as quadratic equation: Cp=a+bT+cT2. The correlation coefficients (R) of measured results of K1TNPG, K2TNPG and K3TNPG are 0.987, 0.999 and 0.993, respectively. The deviation analysis indicates that DSC method is effective and can be used to measure the specific heat capacity of other energetic materials. |
