Abstract:
The density and viscosity of dimethylsulfoxide (DMSO) + acetonitrile (AN) mixtures were determined over the whole composition range at T= (298.15, 303.15, 308.15, 313.15, and 318.15) K. Since experimental density values showed to be very sensitive to water content, the water-free values of these magnitudes were determined by extrapolation from data obtained on ternary mixtures with small, well-determined, amounts of water and constant xDMSO/xAN. Excess volumes of the anhydrous mixtures show positive values with a quite symmetrical behavior. Viscosity data were satisfactorily fitted with a sixth degree polynomial. Excess viscosities as well as activation parameters for viscous flow in the mixtures were calculated. © 2009 American Chemical Society.
