Magnesium chloride, dioxane and water-ternary phase diagram and powder XRD data

摘要

The separation and purification of magnesium chloride from brines, and concentration of other valuable elements from those brines are important for industrial use. Basic data are needed to design industrial processes. Therefore, the phase equilibrium of the ternary system magnesium chloride–dioxane-water (MgCl_2-C_4H_8O_2-H_2O) at five different temperatures (278.15K, 288.15K, 298.15K, 308.15K and 318.15K) is studied systematically by an isothermal solution saturation method. The achieved data are presented and compared to literature, if existing. The XRPD pattern of MgCl_2·6H_2O·C_4H_8O_2 and MgCl_2·2C_4H_8O_2 are also obtained and presented.
