Excess molar enthalpies, H-m(E) of binary mixtures of ethane-1,2-diamine (EDA) with methanol, ethanol, propan-l-ol, propan-2-ol, butan-1-ol and butan-2-ol were calculated from calorimetric data at T= 298 K and atmospheric pressure (81.5 kPa) with a Parr 1455 solution calorimeter. All the binary mixtures showed exothermic behavior over the entire range of compositions. From the experimental results, the excess partial molar enthalpies, H-i(E) and excess partial molar enthalpies at infinite dilution,H-i(E)-infinity were calculated. Excess molar enthalpies, H-i(E) values increase as the chain length of the alkanol is increased, showing minimum values varying from -4395 (methanol) to -1987 J center dot mol(-1) (butan-2-ol). The minimum H-m(E) values were observed about 0.4 mol fraction of ethane-1,2-diamine (EDA). The experimental results were discussed in terms of intermolecular interactions, particularly hydrogen-bonding interactions between like and unlike molecules. Finally the experimental results were correlated by the Redlich-Kister equation and the three thermodynamic models (Wilson, NRTL, and UNIQUAC) based on the local composition theory.
