Liquid-liquid equilibrium for ternary systems of water plus tetrahydrofurfuryl alcohol plus isopentanol/1-hexanol at 303.2, 313.2, 323.2 K

In 101.3 kPa, Liquid-liquid equilibrium (LLE) data of water + tetrahydrofurfuryl alcohol (THFA) + isopen tanol/1-hexanol were measured at 303.2, 313.2, and 323.2 K. The distribution coefficient and separation coefficient of THFA extracted from water were used to assess the utility. The measured data were connected through the NRTL and UNIQUAC models to regress the binary interaction parameters. The GUI-MATLAB was used to check the consistency of the calculated binary interaction parameters and LLE data. The RMSD of both models were less than 0.0077 to prove their consistency with the experimental data. (C) 2021 Elsevier Ltd.

Automated summary

Liquid-liquid equilibrium (LLE) data of water + tetrahydrofurfuryl alcohol (THFA) + isopentanol/1-hexanol were measured at different temperatures. The distribution coefficient and separation coefficient of THFA were used for evaluation. The NRTL and UNIQUAC models were employed to connect the measured data and calculate the binary interaction parameters. The consistency between the calculated parameters and experimental data was confirmed using GUI-MATLAB.
