In order to efficiently exploit and utilize brominerich underground brine resources of China, the quinary system NaBr−KBr−MgBr 2 −SrBr 2 −H 2 O at 273.15 K was studied in detail by the isothermal dissolution equilibrium method. According to phase equilibrium data in the quinary system, the threedimensional space phase diagram of the quinary system was constructed, and there were two invariant points, seven univariate curves, and five solid-phase crystallization regions NaBr•2H 2 O, KBr, SrBr 2 •6H 2 O, MgBr 2 •6H 2 O, and KBr•MgBr 2 •6H 2 O. And three simplified dry salt phase diagrams were drawn for the quinary system under saturation conditions of NaBr•2H 2 O, KBr and SrBr 2 • 6H 2 O. Furthermore, the solubilities of salts in the quinary systems NaBr−KBr−MgBr 2 −SrBr 2 −H 2 O at 273.15 K (saturated with NaBr•2H 2 O, KBr, and SrBr 2 •6H 2 O) were theoretically predicted by using the Pitzer model, and the calculated solubilities were in good agreement with the experimental values on the whole.

To efficiently exploit and utilize bromine-rich brine resources of China, solid–liquid phase equilibria of the quinary system NaBr–KBr–MgBr2–SrBr2–H2O (saturated with KBr) and the quaternary system NaBr–MgBr2–SrBr2–H2O at 308.2 K were studied in detail by the isothermal dissolution equilibrium method. The dry salt phase diagram of the quinary system NaBr–KBr–MgBr2–SrBr2–H2O (saturated with KBr) includes one invariant point, three isothermal dissolution curves, and three crystallization regions (NaBr·2H2O, KBr·MgBr2·6H2O, and SrBr2·6H2O) under the condition of KBr saturation. And the crystallization region of KBr·MgBr2·6H2O is the smallest, so KBr·MgBr2·6H2O is difficult to crystallize and precipitate. Similarly, The dry salt phase diagram of the quaternary system NaBr–MgBr2–SrBr2–H2O is composed of two invariant points, five isothermal solubility curves, and four crystallization fields, which are hydrate salts NaBr·2H2O, MgBr2·6H2O, and SrBr2·6H2O and anhydrous simple salt NaBr. The crystallization region of MgBr2·6H2O is the smallest, the solubility of magnesium bromide is the largest, and it is difficult to crystallize and precipitate in this saturated solution. Furthermore, the mixing ion-interaction parameter ΨNa, Sr, Br of Pitzer’s model is fitted, which can be used for the subsequent prediction of phase equilibria containing strontium system. In addition, the solubilities of salts in the quinary system and the quaternary subsystem were theoretically predicted, and the experimental value was compared with the calculated value. The calculated value was in good agreement with the experimental value.
