Description
Summary:Densities and viscosities have been measured at 308.15 K over the entire range of composition for binary liquid mixtures of dimethyl sulfoxide with ethylene glycol, diethylene glycol, triethylene glycol, poly(ethylene glycol)-200, poly(ethylene glycol)-300, propylene glycol, and polypropylene glycol-1025. From these results excess molar volumes (V E), deviations in viscosity (Δη), and Grunberg and Nissan interaction parameters (d) have been calculated, and the excess parameters are fitted to a Redlich−Kister equation. The values of V E are negative whereas the values of Δη are positive over the entire composition range.
