Understanding the thermodynamic behavior of such mixtures is essential for optimizing their formulation. In this study, the excess molar enthalpy () a key property reflecting molecular interactions and non-ideality was measured for four ternary blends containing 2-(2-methoxyethoxy)ethanol, 2-(2-ethoxyethoxy)ethanol, 2-methoxyethanol, and 2-phenoxyethanol, each mixed with ethanol, at 298.15 and 313.15 K under 0.1 MPa using a quasi-isothermal flow calorimeter. The experimental results were correlated using the Redlich–Kister, NRTL, and UNIQUAC models, while the predictive performance of the Modified UNIFAC (Dortmund) model was also assessed. Positive values were obtained for all mixtures, indicating endothermic mixing and dominant dispersive–dipolar interactions. Among the applied models, the Redlich–Kister equation provided the best correlation with experimental data. The results contribute valuable thermodynamic benchmarks for modeling the energetics of oxygenated fuel blends and improving predictive approaches for complex liquid mixtures.
