| 摘 要： | 用C80微热量仪测定了298.15K时斯蒂芬酸(TNR)在溶剂乙醇(EtOH)中溶解焓及热动力学行为。得到了描述该物质溶解焓(ΔsolH)的经验公式。该公式为:ΔsolH=30.108+4756.04b-616.619b1/2,并由此得到了该物质的标准摩尔溶解焓、相对表观摩尔焓、相对偏摩尔焓以及配合物的稀释焓的经验公式。溶液反应的动力学方程为:γ=-6.60613+0.5678x,由此得到了该溶解反应的速率常数及反应级数:n=0.56875;k=1.94×10-3s-1。

| Abstract: | The enthalpy of solution and thermokinetic behavior of 2,4,6-trinitro-1,3-benzenediol (TNR) dissolved in the common solvent alcohol (EtOH) are determined with SETARAM C80 calorimeter at 298.15 K. The empirical formula describing the enthalpy of solution of the studied compounds dissolved in alcohol is obtained. The resulting formula is:ΔsolH=30.108+4756.04b-616.619b1/2. From the formula, the empirical formulas describing the standard molar enthalpy of solution (ΔsolHθm(b=0)), the relative enthalpy (Li) are obtained. The kinetic formula of the dissolution reaction is γ=-6.50613+0.5678x, from which the reaction order(n) and reaction rate constant(k) of the reaction are deduced as:n=0.56875; k=1.94×10-3 s-1. |
