The viscosity B-coefficients and partial molar volumes have been measured for N,N-dimethylformamide and formamide in methanol + acetonitrile solvent systems and for N,N-dimethylformamide in water + acetonitrile mixed solvents. These data are used to calculate the solute contribution to the activation ...

Measurements of the viscosity of solutions of NaCl and Nal in acetonitrile-water mixtures at 25 掳C, and of the self-diffusion coefficients of CH3CN and H2O in these liquids, using 14C and 3H as tracers, are reported. The results confirm the previously postulated preferential solvation of the...
Densities and viscosities for the system, water + acetonitrile, have been determined for the entire range of composition at temperatures ranging from 303.15 to 323.15 K. Density, excess molar volume, viscosity, thermodynamic activation parameters for viscous flow and some of their excess ...
