Calorimetric measurements were performed for six binary mixtures of isoamyl acetate + alcohols (methanol, ethanol, 1-propanol, 2-propanol. 1-butanol and 2-butanol) by a Parr 1455 solution calorimeter over the entire composition range at T=298.15 K and atmospheric pressure. The results were applied to calculate excess molar enthalpies H-m(E) and excess partial molar enthalpies H-i(E). The H-m(E), values were positive over the whole of composition range and become more positive with increasing the chain length and steric hindrance of the alkanols. The trend of the H-m(E), data was interpreted in terms of the self-association of pure alkanols, dipole-dipole interactions between ester molecules and cross-association between unlike molecules (ester-alkanol). The correlations of experimental data were performed by Redlich-Kister equation and NRTL and UNIQUAC models. (C) 2011 Elsevier B.V. All rights reserved.
