“…Zhang studied the liquid–liquid equilibrium for the ternary system of 2-ethyl-1-hexanol + ethylene glycol + extractant at different temperatures, which provided theoretical guidance for exploring the extraction capacity at different temperatures. Yi studied the liquid–liquid equilibrium for ternary systems of 2-ethyl-1-hexanol, ethylene glycol, and four extractants at 298.2 K, which provided an idea for selecting good extractants. …”

To recover 2-ethyl-1-hexanol and 1,2-propanediol from waste polyester alcoholysis products, liquid−liquid equilibrium (LLE) data for the ternary system of 2ethyl-1-hexanol + 1,2-propanediol + (water, n-heptane) at different temperatures (303.2, 313.2, and 323.2 K) were studied at 101.3 kPa. The distribution coefficient (D) and selectivity coefficient (S) were used as indicators to assess the separation effect. The NRTL and UNIQUAC models were used to correlate the experimental data and the root mean square deviation (RMSD) values were calculated to be less than 0.75 and 0.97%, respectively. Finally, the consistency between the experimental data and the regression parameters was verified using the GUI-MATLAB tool. σ-Profiles are used to discuss the interactions of substances in this work. It was found that both extractants could separate and extract 2-ethyl-1-hexanol and 1,2-propanediol effectively, with water being more effective.
