Liquid-liquid extraction data of methyl ethyl ketone from n-hexane using ethylene glycol at 298.15–313.15 K

In order to remove methyl ethyl ketone from the lower fractions of C 6 in the high temperature Fischer-Tropsch synthetic oil, the liquid-liquid equilibrium (LLE) experiments for methyl ethyl ketone   +   n-hexane   +   ethylene glycol were carried out and the LLE data were measured at 298.15, 303.15, 308.15 and 313.15   K under atmospheric pressure. The analysis results demonstrated the feasibility of separating methyl ethyl ketone from n-hexane using ethylene glycol with the extraction method . Moreover, the NRTL and UNIQUAC models were successfully applied to correlate the LLE data with RMSD′ values of 0.0197 and 0.0313, respectively, which indicated that NRTL model showed a higher accuracy.
