ABSTRACT

Densities and viscosities for dimethylsulfoxide (DMSO) with methanol, ethanol, 1-propanol, and 2-propanol have been measured as a function of mole fraction at T = (303.15, 308.15, 313.15, 318.15, and 323.15) K and atmospheric pressure. From the measurements, excess molar volumes (V E m), excess viscosities (gE), and Grunberg and Nissan interaction parameters (e) have been calculated. The excess parameters are fitted to a Redlich Kister equation. Excess molar volumes (V E m) are negative for (DMSO + methanol, + ethanol) systems throughout the whole range of composition. The (DMSO + 1-propanol) system shows both positive and negative excess molar volumes and (DMSO + 2-propanol) shows positive excess molar volume, hardly any negative value is observed in alcohol rich-region. The excess viscosities and interaction parameters of all the mixtures are negative except for the (DMSO + methanol) system which is positive.
