“…The phase behavior (SLE) of the ternary system is affected by the properties of the solvent and the salts . Compared with the liquid–liquid equilibrium (LLE) behavior of the CsCl + TMU (tetramethylurea) + H 2 O system at 298.2 and 308.2 K, the CsCl + NMP + H 2 O system studied in this paper is a solid–liquid equilibrium (SLE). This is caused by the larger polarity of NMP , (μ = 4.09 D) than that of TMU , (μ = 3.37 D).…”

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.
