“…For example, the solubilities of NaCl/KCl/LiCl/LiBr + CH 3 OH/C 2 H 5 OH/CH 3 COCH 3 + H 2 O , in the temperature range of 293.15–333.15 K were determined. The solubilities of MCl (M = Na, K, Rb, Cs) in ethylene glycol/glycerin + H 2 O at different temperatures were discussed based on the structure and properties of the organic solvent. − For the inorganic salt–alcohol–water ternary system, the structure of alcohols has a great influence on the properties of the solution. The ternary systems of NaCl/KCl + butanols (1-butanol, 2-butanol, 2-methyl-1-propanol) + H 2 O at 298.15 K and NaCl + pentanols (1-pentanol, 2- pentanol, 3-pentanol) + H 2 O at 298.15 K were investigated to discuss the effect of the carbon chain on the phase behavior of the ternary systems.…”

In this paper, the solid–liquid equilibrium of N-methylpyrrolidone (NMP) + MCl (M = Na, K, Rb, and Cs) + H2O ternary systems was investigated at three temperatures (T = 288.2, 298.2, and 308.2 K). The isothermal solubility, density, and refractive index of the saturated ternary systems were obtained. At the same temperature, as the NMP content in the mixed solvent increases, the solubility of the salt decreases significantly, and the density change trend is consistent with the solubility. However, as the NMP content in the mixed solvent increases, the refractive index increases. As the experimental temperature increases, the solubility and density increase, while the refractive index decreases. Moreover, the semi-empirical four-parameter equation was used to fit the experimental data.

Complete phase diagrams and physico-chemical properties for the ternary system (CsCl + NaCl + H 2 O) were determined at T = (298.15, 308.15, and 318.15) K, respectively. The X-ray diffraction method and Schreinemaker's wet residue method were used to verify the solid phase. The phase diagrams show this ternary system is a complex type. Three crystallization regions were found corresponding to the single salt NaCl, a compound CsCl•2NaCl•2H 2 O, and a solid solution series [Cs 1−x (Na•H 2 O) x ]Cl (x in [Cs 1−x (Na•H 2 O) x ]Cl changed from 0 to 0.43 (298.15 K), 0.39 (308.15 K), and 0.36 (318.15 K) at each temperature. With rising temperature, the crystallization area of NaCl increased, but CsCl•2NaCl•2H 2 O and [Cs 1−x (Na•H 2 O) x ]Cl decreased simultaneously. However, density and refractive index increased with increasing CsCl concentration.

“…In previous work, our research groups have focused on the solubility of alkali metal (Na, K, Rb and Cs) salts in water + organic solvent. [9][10][11] In this work, the equilibrium solubility of NaNO 3 and KNO 3 in the mixed solvent HOCH 2 CH(OH) CH 2 OH + H 2 O were determined by the density-refractive index method. The density and refractive index of the saturated and unsaturated solutions were also measured.…”

Materials. All the chemicals (purity > 99.5 %), including sodium nitrate, potassium nitrate, and glycerol were purchased from Sinopharm Chemical Reagent Co. Ltd., and used without further purification. The salt was dried to constant weight for 48 h at 110 °C and stored in desiccators prior to use. Double-distilled water was used throughout this work. Apparatus and Procedure. All samples were prepared by mass with electronic balance (AL204, Mettler Toledo, accuracy of ±1 • 10 −4 g). The experimental apparatus and process are the same as those reported in our former work. 9-11 The mixed solvent (glycerol and water) was firstly placed in a 10 ml syringe (the mass fraction of glycerol in the mixed solvent varied from 0.0 to 1.0). Excessive amounts of NaNO 3 and KNO 3 were then added into the mixed solvent. Next, the samples were stirred for 48 h and settled for a further 24 h to ensure that equilibrium was established. The temperature was controlled within an accuracy of ±0.1 K. After equilibrium was achieved, the solutions were withdrawn and analysed. The unsaturated solutions were prepared by adding salt to the mixtures of glycerol-water at a certain ratio. Refractive index and density of both saturated and unsaturated solutions were determined using RXA 170 refractometer (Anton Paar) and DMA 4500 vibrating tube densimeter (Anton Paar) with a precision of 4 • 10 −5 and ±1 • 10 −5 g cm-3 , respectively. Both the instruments were calibrated prior to initiation of each series of measurements, using air and double-distilled water as reference substances. The content of the salts and glycerol was analysed using density-refractive index method, 9 because refractive index and Phase Equilibrium of NaNO 3 /KNO 3 in Glycerol + H 2 O Mixed Solvent System at 288.15 K and 298.15 K Solubility, density, and refractive index were determined for the ternary systems of NaNO 3 /KNO 3 + glycerol + H 2 O at 288.15 K and 298.15 K. The solubility of the salts was calculated by the method of combining density and refractive index. In all cases the solubility of the salts decreased with the increase in glycerol content. A reverse trend for the refractive indices was observed. However, NaNO 3 density tended to decrease and KNO 3 density tended to increase with the addition of glycerol in the solution. Moreover, the experimental data were correlated using a four-parameter and seven-parameter empirical equation for the saturated and unsaturated solutions, respectively. Therefore, research of such kind of system has potential theoretical and practical application for the purification process and thermodynamic chemistry.
