Liquid–Liquid Equilibria Data and Thermodynamic Modeling of {Mesityl Oxide + Diethoxymethane + Water} Ternary System at 303.15, 313.15, 323.15 K Under 101.325 kPa

Abstract

The liquid–liquid equilibrium (LLE) of the mesityl oxide + diethoxymethane + water was determined at 303.15, 313.15 and 323.15 K under 101.325 kPa, which was consistent with the Treybal’s type II ternary phase behavior. The distribution coefficients (D) and selectivity coefficients (S) were used to evaluate the extraction ability of mesityl oxide to extract diethoxymethane from water. The experimental data were correlated with the NRTL and UNIQUAC thermodynamic models, and the RMSD values are both less than 0.47%, indicating that the two models can well correlate the experimental data.
