摘要
在温度298.15 K,采用C80微热量热仪测定了三硝基间苯三酚(TNPG)在去离子水(H2O)的溶解焓及热力学参数。由多项式拟合得到该物质溶解焓(ΔdissH)的经验公式ΔdissHm=106.799266+15538.58581-2352.19194b1/2b,并计算获得标准摩尔溶解焓、相对表观摩尔焓和相对偏摩尔焓。同时,对溶液反应的动力学进行研究,获得了动力学方程以及相应的反应速率常数和反应级数。
A SETARAM C80 calorimeter was used in the experiment to measure the enthalpy of dissolution and thermodynamic properties of trinitrophloroglucinol （TNPG） dissolved in deionized water （H20） at 298.15 K. The empirical formula for the enthalpy of dissolution was calculated by polynomial expressions. The fomula is： Adiss Hm = 106. 799266 - 2352. 19194b^1/2 ＋ 15538. 58581 b. The standard molar enthalpy of dissolution,the relative apparent molar dissolution enthalpy and the relative partial molar enthalpy also were obtained from the experimental data of the enthalpy of dissolution of TNPG in water. The kinetic formula was obtained. From the formula the rate constant and reaction order are deduced.
