✦ Synopsis

The densities, viscosities, and uhrasonic velocities of pure ethanol, 1-hexanol, 1-octanol, acetonitrile, N,N-dimethylformamide, and of the binary mixtures of ethanol with 1-hexanol and 1-octanol, and those of acetonitrile with N,N-dimethylformamide were determined at 303.15 IC The excess adiabatic compressibility, excess intermolecular fee length, excess volume, excess viscosity, excess acoustic impedance, and the molecular association have been calculated from the experimental data. These parameters are used to discuss the nature and the extent ofintermolecular interactions in the mixtures.
