Excess volumes of dimethyl sulphoxide mixtures

Abstract

The volumes of mixing (excess volumes) for dimethyl sulphoxide with carbon tetrachloride, chloroform, benzene, acetone, and water have been measured at 25.00º and 35.00º with a dilatometer. The values for the equimolar mixtures at 25.000 are -0.596, -0.112, -0.304, -0.511, and -0.944 cm³ mol^-1 respectively. The results are compared with available density measurements on these systems and qualitatively compared with the corresponding acetone systems.
