Methanol-renewable diesel blends with methanol energy shares ranging from 5% to 90% were prepared, and co-solvents were titrated until a clear single-phase mixture was obtained. Ternary phase diagrams were used to characterize the phase behavior at room temperature. Intermolecular interactions governing blend stability were analyzed using Hansen solubility parameters, complemented by ATR-FTIR spectroscopy to assess changes in hydrogen bonding and molecular polarity. The results demonstrate that the co-solvent molecular structure strongly influences blending performance. Higher alcohols exhibited superior effectiveness compared to the ester, with 1-dodecanol providing the highest stabilization efficiency, followed by 1-octanol, while methyl butyrate showed the poorest performance. The enhanced performance of higher alcohols is attributed to their ability to balance dispersion forces and hydrogen-bonding interactions, as supported by Hansen solubility parameter analysis.
