摘要: Liquid-liquid equilibrium data have been measured for one ternary system of water + N-methyl-2-pyrrolidone 1-hexanol and three quaternary systems sodium chloride, potassium or acetate at temperatures (283.15 323.15) K under atmospheric pressure. The liquid-phase splitting the can be enhanced by adding same percentage salts (sodium acetate), influence follows order chloride > acetate. experimental were also compared with values calculated electrolyte-NRTL model. In general, model reproduces reasonably LLE phase diagrams.
