Density and viscosity of anhydrous mixtures of dimethylsulfoxide with acetonitrile in the range (298.15 to 318.15) K

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 mag...
