Good Agreement

Excess molar volumes, VE, have been measured for binary liquid mixtures of dimethyl sulfoxide (DMSO) with xylenes (o- xylene, m- xylene and p-xylene) at 298.15 K and atmospheric pressure. The excess volumes values were found negative over the entire composition range for all the mixtures. The VE values increase in order: p-xylene[ m-xylene[ o-xylene. The Flory and Prigogine-Flory-Patterson (PFP) thermodynamic theories of solution have been used to analyze the VE data. The calculated VE values were found to be in good agreement with the experimental data.
