Abstract

Diffusion coefficients are presented as a function of pressure to 10 000 atmospheres for the following systems:

\begin{matrix} 50 mol percent n −heptane −50 percent {CS}_{2} 0^{\circ} {−20}^{\circ} {−40}^{\circ}; \\ 50 mol percent 2,4 dimethylpentane −50 percent {CS}_{2} 20^{\circ} {−40}^{\circ}; \\ 50 mol percent toluene −50 percent {CS}_{2} 20^{\circ} {−40}^{\circ}; \\ 50 mol percent methylcyclohexane −50 percent {CS}_{2} 0^{\circ} {−20}^{\circ} {−40}^{\circ}; \\ 50 mol percent n −octane −50 percent {CS}_{2} 20^{\circ} C; \\ 50 percent chlorobenzene −50 percent {CS}_{2} 20^{\circ} {−40}^{\circ}; \\ 80 percent chlorobenzene −20 percent {CS}_{2} 40^{\circ}; \\ 50 percent n −butanol −50 percent {CS}_{2} 20^{\circ} {−40}^{\circ}; \\ 50 percent iso−butanol −50 percent {CS}_{2} 20^{\circ} {−40}^{\circ}; \end{matrix}

using S³⁵ tagged CS₂. The results are interpreted in terms of the activation volume, enthalpy, and entropy, and conclusions are drawn concerning the effect of pressure on the structure of the liquids.
