The thermophysical properties of liquid mixtures are very important as fundamental data in process design and are also helpful in understanding characteristics of solutions.Comparing thermophysical properties with spectroscopic measurements, different contributions to the non-ideal behavior of liquid mixture can be evaluated. The proposed research work is a detailed thermophysical and spectroscopic studies of structural and interactional behavior of mixtures of alkanediols in non-aqueous media. The aim of the present work is twofold: first is to enlarge the thermodynamic database for mixtures...
