用差示扫描量热法(DSC)测定了含能材料2,4,6-三硝基-1,3,5-苯三酚(TNPG)、一取代(Na1TNPG)、二取代(Na2TNPG)、三取代钠盐(Na3TNPG)定压下的连续比热容,计算了在50～100 ℃温度范围内每间隔5 ℃的焓差值和熵变值.从实验得出的比热容与温度的关系为: Cp(J·g-1·℃-1)=a+bT+cT2+dT3,TNPG取代钠盐例外d=0.有关误差分析表明,该测试方法是有效的,并可用于其它含能材料的比热容的测量.另外,实验相关系数接近1,表明这些化合物的比热容呈现很好的规律性.

The continuous specific heat capacities at constant pressure (Cp) of 2,4,6-trinitro-1,3,5-trihydroxybenzene(TNPG), mono-substituted sodium (Na1TNPG), di-substituted (Na2TNPG) and tri-substituted (Na3TNPG) 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 from 50 ℃ to 100 ℃. The temperature dependence of Cp were determined from the experimental values as Cp(J*g-1*℃-1)=a+bT+cT2+dT3 with the exception d=0 for the substituted sodium salts of TNPG. The deviation analysis indicates that DSC method is effective and can be used to measure the specific heat capacity of other energetic materials. The correlation coefficients that are close to 1 show that the Cp values of these compounds are well-regulated.
