Abstract:
The limiting mutual diffusion coefficients of primary alcohols (C1–OH to C14–OH) in n octane and 1 octanol and of normal alkanes (C1 to C14) in 1 octanol were measured using the Taylor dispersion technique in the temperature range 298–374 K. The data were interpreted using the rough hard sphere theory. The combined effects of translational–rotational coupling and hydrogen bonding were extracted from experimental data for each solute–solvent pair at each temperature. For diffusion of alcohols in n octane, the polarity of the solute molecules tends to increase the amount of coupling. For diffusion of alkanes and alcohols in 1 octanol, the deviations from smooth hard sphere behavior showed a strong temperature dependency indicating the effects of hydrogen bonding. For diffusion of alcohols in 1 octanol, stronger temperature dependency of the deviations compared to alkane solutes indicate strong interactions between solute alcohol molecules and 1 octanol molecules.
