摘要：

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 free energy for viscous flow, Delta mu (not equal)(13), for these systems. It is found that the Delta mu (not equal)(13) values are simply related to the corresponding enthalpies of transfer.
