ABSTRACT
Total vapor pressure measurements and vapor-liquid equilibrium data are reported for the pure diethyl sulfoxide and diethyl sulfoxides + water binary system in the temperature range of (298.15 to 318.15) K. All mixtures show negative deviations from ideality due to strong interactions between diethyl sulfoxide and water molecules that are even stronger than those between dimethyl sulfoxide and water.
