| Abstract | The interdiffusion coefficient Daw of six hydrophobic benzene derivatives (a
= chlorobenzene, 1,2-dichlorobenzene, 1,4-dichlorobenzene,
bromobenzene, 1,2-dibromobenzene, 1,4-dibromobenzene) in aqueous
solution (w) at 25 °C is measured at different concentrations below 10-5
solute mole fractions using the Taylor dispersion technique. On the
basis of the experimental uncertainty around 4%, a distinct
concentration dependence is not recognizable. Analysis of the
interdiffusion coefficients with the Stokes−Einstein equation shows
greater
values than expected from the limit of a complete solute−solvent
contact (“stick limit”), and in addition substance-specific deviations.
Chemical engineering correlations for presently available from the literature yield unsatisfactory results for this class of predominantly hydrophobic compounds. |
