Liquid–Liquid Equilibrium Study of Ternary Systems of (Water + Furfuryl Alcohol + Solvents) at 303.2, 313.2, and 323.2 K

Abstract

The liquid–liquid equilibrium (LLE) data of water + furfuryl alcohol + trichloromethane /methyl isopropyl ketone were determined at 303.2, 313.2, and 323.2 K under 101.3 kPa. The distribution coefficient (D) and separation factor (S) were evaluated for the separation effect of solvents. The nonrandom two-liquid and universal quasichemical models were used to correlate the experimental LLE data and obtain the binary interaction parameters. Meanwhile, the root mean square deviations and absolute average deviation of the two models did not exceed 0.0094 and 0.0066, respectively, which shows that the experimental LLE data can be accurately correlated through the two models. GUI-MATLAB was used to verify the consistency between the LLE data and the calculated binary interaction parameters. σ-Profiles were used to analyze the interaction between the molecules of each substance, further confirming the accuracy of the experimental results.
