ABSTRACT

In this work, solid-liquid equilibria (SLE) data for ternary sodium 1-naphthalenesulfonate + sodium 2-naphthalenesulfonate + water system was measured at (283.15, 303.15 and 323.15) K, respectively. The diagrams for solid liquid phase of the ternary system were well-established by the measured solubility data. The solid phases formed in the studied system were determined by the method of Schreinemaker s wet residue. Moreover, the density of equilibrium liquid phase was gained in the process. At each temperature, there are two pure solids forming. They are sodium 1-naphthalenesulfonate and sodium 2-naphthalenesulfonate in the ternary system. The solubility data for the ternary system were calculated and regressed by NRTL model, giving acceptable results for the investigated systems.
