This study presents experimental data for five binary mixtures of 2-propanol with glycol ethers: 2-(2-methoxyethoxy)ethanol, 2-(2-ethoxyethoxy)ethanol, 2-methoxyethanol, 2-phenoxyethanol, and 2-butoxyethanol. Measurements of excess molar enthalpy (), density (ρ), speed of sound (u), and refractive index (nD) were performed over the temperature range 293.15 K–323.15 K at 0.1 MPa. Derivative thermodynamic properties, excess molar volume (), isentropic compressibility (ks), and refractive index deviation (ΔnD), were calculated from the experimental data. Density data were correlated using PC-SAFT and Peng–Robinson equations of state, while polynomial equations were employed to fit ρ, u, nD, and ks as functions of composition. The Redlich–Kister equation was used to fit and ΔnD. Excess molar enthalpy () was modeled using both the Redlich–Kister correlation and thermodynamic activity coefficient models, UNIQUAC, NRTL, and Modified UNIFAC, to interpret molecular interactions. All the studied mixtures exhibit endothermic behavior. The results contribute to a deeper understanding of the behavior of alcohol/glycol ether mixtures and their potential application in fuel formulations.
