In the experimental measurement part, liquid-liquid equilibrium data have been measured for one ternary system of water + DMSO + 1-pentanol and six quaternary systems of water + DMSO + 1-pentanol + potassium acetate, + sodium acetate, + potassium chloride, + potassium bromide, or + sodium bromide at temperatures from 283.15 K to 323.15 K under atmosphenic pressure. In the LLE calculating part, the experimental LLE data were compared with the values calculated by the NRTL and Electrolyte-NRTL model. The ground average deviation values less than 0.013. This correlated result tallied with the experimental data
