摘要: 研究了MgCl2-MgSO4-H2O、H3BO3-MgCl2-H2O、H3BO3-MgSO4-H2O三个三元体系及由它们所组成的四元体系H3BO3-MgCl2-MgSO4-H2O在288.15K的溶解度等温线。确定了六水硫酸镁的存在,讨论了各相之间的关系及各化合物相互间的盐析作用。

Abstract: In the present paper the solubility isotherm of three ternary systems MgCl2-MgSO4-H2O, H3BO3-MgCl3-H2O, H3BO3-MgSO4-H2O and quarternary system H3BO3-MgCl3-MgSO4-H2O at 283.15 K have been studied in detail.The existence of MgSO4·6H2O in system MgCl2-MgSO4-H2O was verified. The correlations of equilibrium phases and the salting-out effecis between components were discussed.
