摘要：

Experimental data of the molar excess enthalpy of 17 binary alkanol+amine mixtures are presented obtained at 298.15 K by using an isoperibolic titration calorimeter (LKB 8700). The data are used for testing the ERAS model which accounts for self association and cross association of mixtures containing hydrogen bonds in the liquid state as well as for free volume effects based on an equation of state which incorporates the chainlike association of the molecules, Self association and cross association enthalpies of the hydrogen bonds are obtained as well as association constants providing an insight into the intermolecular structure of this kind of liquid mixtures.
