| 摘 要： | 本文应用微扰理论计算了由甲醇—乙醇—水—NaCl、LiCl、CaCl_2、NaBr、NaI所构成体系的等压气液平衡。证明了由实验结果发现的当混合溶剂的相对组成固定时,体系的沸点与加入盐量间的线性关系。计算中涉及的LJ参数,我们采用纯物质的蒸气压及密度数据进行拟合。计算结果与实验测定值符合较好。

| Abstract: | In this paper the isobaric vapor-liquid equilibrium of methanol-ethanol-water-NaCl,LiCl,CaCl_2,NaBr and NaI has been calculated with perturbation theory.The linear relationship betweenboiling temperature and the salt mole fraction is provided,when the tenary composition is fixed.Theparameters of LJ are correlated from the pressure and density of the pure components.The results fromperturbation theory correspond to the experimental value well. |
