Viscosity, density, diffusion and self-diffusion data have been collected on the system N-methylpyrrolidone+ water at 20°C over the entire composition range. From density and vapour pressure data, affinities, were computed and compared with the velocity cross-correlation coefficients. Good agreement was found between the interpretation of dynamic, and thermodynamic data. Both data are in favour of preferential solute-solvent interactions leading to short-lived hydration aggregates.

Abstract

Viscosity, density, diffusion and self-diffusion data have been collected on the system N-methylpyrrolidone+ water at 20°C over the entire composition range. From density and vapour pressure data, affinities, were computed and compared with the velocity cross-correlation coefficients. Good agreement was found between the interpretation of dynamic, and thermodynamic data. Both data are in favour of preferential solute-solvent interactions leading to short-lived hydration aggregates.
