The study was carried out at temperatures from 293.15 to 333.15 K, considering intervals of 5 K. The pressure was the atmospheric pressure of 0.078 MPa. The binary mixtures were prepared for the whole range of composition, at intervals near 0.1 in mole fraction. Isobaric thermal expansion coefficients were calculated, and their variation with respect to temperature and the alkane were examined. Excess molar volumes of the mixtures were obtained, resulting in positive deviations from ideality for the four systems. A relation between the magnitude of the deviation and the size of the alkane was observed. An empirical approach to modeling the excess molar volume, the Redlich–Kister correlation, was applied. Additionally, the theoretical model, the Prigogine–Flory–Patterson (PFP) model, was fitted to the excess molar volume data. The PFP model parameter was analyzed, and a relation with the size of the alkanes was found. The values of the parameters were of an order that agrees with the nature of the compounds in this work.

The extraction capabilities of the selected solvents (ethylene glycol (EG), <i>N</i>-formylmorpholine, 1,3-propanediol, 1,4-butanediol, 1,2-propanediol, <i>N</i>-methyl-2-pyrrolidone (NMP), <i>N</i>,<i>N</i>-dimethylacetamide, and benzyl alcohol) for separating heptane and thiophene were assessed based on the distribution constant (<i>D</i>) and separation factor (<i>S</i>).

Therefore, to balance <i>D</i> and <i>S</i> simultaneously, mixtures of EG and NMP at different molar ratios were used as extractants. Molecular-level investigation into the separation mechanism was conducted via molecular dynamics simulations and density functional theory calculations. The enhanced <i>S</i> value of EG was attributed to a significant difference in its interaction energies with thiophene and heptane, whereas the enhanced <i>D</i> value of NMP resulted from a more negative solvation-free energy upon binding thiophene. Finally, a comparison of the thermodynamic models showed that the nonrandom two-liquid (NRTL) model and the universal quasichemical (UNIQUAC) model were equally suitable for correlating the experimental data for the ternary and quaternary heptane + thiophene + solvent systems; the root-mean-square deviation (RMSD) values for the NRTL model were all <1%, whereas the maximum RMSD value for the UNIQUAC model was 1.57%.
