ABSTRACT

The (solid + liquid) equilibrium (SLE) of N,N-diethylformamide (DEF) + MCl (M = Na, K, Rb) + H2O ternary systems were investigated from 288.15 to 338.15 K under atmospheric pressure. The isothermal solubility, density and refraction index of the ternary solution, as well as the solubility at multiple temperature were reported. The (liquid + liquid) equilibrium (LLE) of (DEF + CsCl + H2O) ternary system was further studied at 298.15 and 308.15 K. The Jouyban-Arcee model was utilized to correlate the solubility, density and refractive index data. The LLE was correlated by the Othmer-Tobias and the Bancroft equations. The complete phase diagrams of the (DEF + CsCl + H2O) system were further presented.
