EFFECT OF DISSOLVED SODIUM CHLORIDE SALT ON THE LIQUID-LIQUID EQUILIBRIA OF THE TERNARY SYSTEM ISOPROPYL ETHER-ACETIC ACID-WATER

Abstract

The effect of the addition of the salt sodium chloride on the liquid-liquid equilibrium data of the ternary system isopropyl ether-acetic acid-water has been experimentally investigated at 30°C. Both the solubility (bimodal) curve and the tie-line have been determined for three salt concentrations. The addition of sodium chloride salt enhances the distribution of acetic acid in ether layer. The tie-line data have been correlated by Othmer and Tobias and Hand plots. The ternary solubility and tie-line data at 30°C for this system in the absence of salt have also been experimentally obtained in this work.
