ABSTRACT

The Taylor dispersion method was used to measure limiting interdiffusion coefficients for benzyl alcohol, 2-phenylethanol, 3-phenylpropan-1-ol, 4-phenylbutan-1-ol, and 5-phenylpentan-1-ol in water and tetradecyltrimethylammonium bromide micellar solutions at 298.2 K. These data were used to obtain the degree of binding of the phenylalkanols to the micelles. Partition coefficients of the phenylalkanols between the micellar pseudophase and the bulk aqueous phase and values of the standard Gibbs energy for transfer from the bulk aqueous phase to the micellar pseudophase were calculated. The results are compared with literature values for the sodium dodecyl sulfate and hexadecyltrimethylammonium micellar systems.
