説明
Hydrogen bondings between alcohol and active solvent are studied by infrared spectroscopy, and the equilibrium constants are evaluated for the sixteen systems. Using these values and self-association constants of alcohols, activity coefficients for alcohol-active solvent systems are calculated by the associated solution theory of Flory type. These calculated activity coefficients are compared with experimental values obtained from vapor-liquid equilibrium measurements.<br> From the results, it is found that the spectroscopic information is useful for evaluation of contributions to the nonideal behavior of vapor-liquid equilibria for these systems.<br> Moreover, the correlations between hydrogen-bond shifts and thermodynamic excess functions (GE, HE, VE) for equipmolar mixtures are discussed.
