Self-diffusion in binary liquid solutions of n-paraffins and hexafluorobenzene

Abstract
Steady and pulsed gradient spin echo measurements of the self‐diffusion of both components (1H and 19F NMR) at 80 °C were performed in solutions of C6F6 and each of six n‐paraffins between n‐octane and n‐hexatriacontane across the full concentration ranges; activation energies were also measured. The results are interpreted in terms of hydrodynamic and free‐volume models of binary self‐diffusion.
