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%. •The LLE data for water + ECH + {chloroform or DIPE or MTBE or EA or isopropyl acetate or 2-ethyl-1-hexanol} were measured.•The distribution coefficient and separation factor were calculated.•The reliability of LLE data were verified by the Othmer-Tobias, Bachman and Hand equations.•The NRTL and UNIQUAC models were applied to correlate the experimental LLE data.•The binary interaction parameter values were obtained from the data correlation.
