Using a Parr 1455 solution calorimeter, we determined the excess molar enthalpies, \(H_{\text m}^{\text E}\) of binary mixtures of ethylene glycol diacetate (EGDA) with propan-1-ol, butan-1-ol, pentan-1-ol, hexan-1-ol, heptan-1-ol, and octan-1-ol at 298.15 K and 81.5 kPa. All mixtures showed positive excess molar enthalpies, suggesting repulsive forces and weaker interactions compared to the pure components. These positive values indicate weaker interactions within the mixtures compared to the pure components. Furthermore, the partial molar enthalpies, \(\overline{H}_{\text m,i}\) and the partial molar enthalpies at infinite dilution, \(\overline{H}_{\text m,i}^{\infty }\) were calculated. The Redlich–Kister polynomial equation was used to correlate the experimental data and Wilson, UNIQUAC, and NRTL models were applied to analyze the excess molar enthalpies.
