ABSTRACT

Enthalpies of mixing, heat capacities, densities, viscosities, and refractive indices of dimethyl sulfoxide + dimethyl carbonate, + diethyl carbonate, and + propylene carbonate have been measured at 308.15 K and at atmospheric pressure using a LKB microcalorimeter, a Perkin-Elmer differential scanning calorimeter, an Anton Paar density meter, a Schott-Gerate AVS unit, and an Abbe refractometer, respectively. Heat capacities of pure components were determined in the range (293.15 < T/K < 423.15). The results were fitted to the Redlich-Kister polynomial equation to derive the adjustable parameters and standard deviations to study the nature of the molecular interactions in the mixtures. Results of excess molar enthalpy were interpreted by an extended modified cell model.
