| 摘 要： | 采用等温溶解平衡法研究了 298 K下三元体系NaCl/KCl - PEG400 - H2O的相平衡关系,绘制了相应的相图、密度-组成图和折光率-组成图。研究发现：298 K下,两个三元体系均无分层现象,只存在固液相平衡关系,其平衡相图由不饱和液相区(L)和一固一液区(S+L)构成。PEG400对NaCl、KCl有一定的盐析作用,随着溶液中PEG400含量不断增加单盐溶解度减小。

| Abstract: | Phase equilibria for the aqueous ternary systems NaCl/KCl - PEG400 - H2O at 298 K were studied by an isothermal dissolution method, the densities, and refractive indices were also determined. The corresponding phase diagrams, and diagrams of density vs composition, refractive index vs composition were plotted. Results show that over the entire PEG 400 composition range studied only one liquid phase is obtained, without the biphase region formed at 298 K. The phase diagrams of these two systems consist of one homogeneous area with unsaturated liquid (L), an equilibrium area containing the solid phase of NaCl/KCl and saturated liquid phase (S+L). The solubility of NaCl/KCl decreases with the addition of PEG 400 at 298 K. |
