| 摘 要： | 采用动态激光监测技术测定了温度为293.15~323.15K时TNAZ在乙醇-水二元溶剂体系中的溶解度。结果表明,TNAZ在乙醇-水二元溶剂中的溶解度是温度和溶剂比例的函数,溶解度随温度的升高而增大,温度293.15~323.15K时,TNAZ在纯乙醇溶剂中溶解度变化为0.01349~0.03935mol/mol;293.15K,水的摩尔分数0~0.9189时,TNAZ的溶解度变化为0.01349~0.00007mol/mol。实验数据采用Apelblat经验方程(lnx1=a+b/T+clnT)和(CNIBS)/Redlich-Kister方程(lnx1=B0+B1x2+B2x22+B3x23+B4x24)进行关联,关联效果良好(R20.96)。所测定的溶解度数据与关联模型可以作为基础热力学数据和模型在TNAZ结晶生产实践中应用。

| Abstract: | To investigate the solubility of TNAZ and provide thermodynamic data,its solubility in ethanol-water binary solvent mixtures was determined by a synthetic method from 293.15K to 323.15K employing a laser monitoring observation technique.The results show that the solubility of TNAZ in ethanol-water binary solvent mixtures is a function of temperature and solubility,and it increases with an increase of temperature.In the pure ethanol solvent,the solubility increases from 0.01349mol/mol to 0.03935mol/mol with ... |
