Excess Enthalpies, Heat Capacities, Densities, Viscosities and Refractive Indices of Dimethyl Sulfoxide + Three Aryl Alcohols at 308.15 K and Atmospheric Pressure

Enthalpies of mixing, heat capacities, densities, viscosities, and refractive indices of dimethyl sulfoxide + benzyl alcohol, + 2-phenylethanol, and + 3-phenyl-1-propanol have been measured at 308.15 K and at atmospheric pressure using an LKB micro-calorimeter, a Perkin-Elmer differential scanning calorimeter, an Anton Paar density meter, a Schott-Gerate AVS unit, and an Abbe refractometer, respectively. Heat capacities were determined at (298.15, 308.15, and 318.15) K. The results were fitted to the Redlich−Kister polynomial equation to derive the adjustable parameters and standard deviations and were used to study the nature of the molecular interactions in these mixtures.
