Abstract
Liquid–vapor phase equilibria in dimethyl sulfoxide–alkanol (1-propanol, 1-butanol, and tert-butanol) binary systems are studied using a static method. The total saturated vapor pressure in the temperature range of 293.15–323.15 K is measured. The partial pressures of dimethyl sulfoxide and alkanes have been calculated via integrating the Gibbs–Duhem equation. Excess molar Gibbs energies are described by the Redlich–Kister equation, and the correlation parameters are calculated. The nature of the deviation from the ideal behavior of these solutions is explained by allowing for the presence of competing homo- and heteromolecular interactions and the considerable effect of the length of the alkanols’ hydrocarbon chains has on the values of the thermodynamic parameters.
