Excess Molar Enthalpy Measurements of Multicomponent Alcohol-Ether Mixtures and their Representation in Terms of an Association Model

Our recent studies on the measurement of excess molar enthalpies of alcohol-ether multicomponent solutions are reviewed in terms of a UNIQUAC associated-solution model. In this model, we have taken into account the self-association like alcohols, multicross-association of unlike alcohols and solvation between alcohols and ethers. The UNIQUAC associated-solution model, which includes association constants, solvation constants and optimally fitted binary parameters obtained solely from the pertinent binary correlation, can predict the ternary excess molar enthalpies with an excellent accuracy.
