Experimental determination and modeling of liquid-liquid equilibrium for ternary mixtures composed of water, epichlorohydrin and different solvents

Liquid-liquid equilibrium (LLE) data for water + epichlorohydrin + {chloroform or isopropyl ether or methyl tert-butyl ether or isopropyl acetate or ethylacetate or 2-ethyl-1-hexanol} systems at 308.2 K under 101.3 kPa were determined. The distribution coefficient and the separation factor were used to judge the extraction efficiency of different solvents on epichlorohydrin removal from water. The Othmer-Tobias, Hand, and Bachman equations were applied to check the reliability of the experimental LLE data. Furthermore, the experimental LLE data were successfully correlated with the NRTL and UNIQUAC models with all the RMSD values were less than 0.57%.
