Some Thermodynamic Properties of the Dimethylsulfoxide–Water and Propylene Carbonate–Water Systems at 25 °C

Abstract

Molar excess free energies of the systems dimethylsulfoxide–water and propylene carbonate–water have been calculated from static vapor pressure measurements at 25 °C. Enthalpies of mixing at low water concentrations have also been determined. Possible association interactions in these systems are discussed.
