Molecular enthalpy-entropy compensation

Guillaume et al. [69] presented a high performance liquid chromatographic method for an association study of miconazole and other imidazole derivatives in surfactant micellar using a hydrophilic reagent, Montanox DF 80. The thermodynamic results obtained showed that imidazole association in the surfactant micelles was effective over a concentration of surfactant equal to 0.4 pM. In addition, an enthalpy-entropy compensation study revealed that the type of interaction between the solute and the RP-18 stationary phase was independent of the molecular structure. The thermodynamic variations observed were considered the result of equilibrium displacement between the solute and free ethanol (respectively free surfactant) and its clusters (respective to micelles) created in the mobile phase. [Pg.49]

It is advised therefore that the extrathermodynamic analysis based on the enthalpy-entropy compensation effect should be restricted to the (supra)molecular recognition phenomena governed by cooperative weak interactions. [Pg.91]

From strictly formalistic considerations, much larger surface tension changes are achieved in RP-HPLC than in HP-HIC separations of polypeptides and proteins, and these differences underpin the relative facility of these techniques to follow the same types of molecular binding events (and their perturbations) to the same level of physicochemical discrimination. Obviously, analogous approaches linking the interaction thermodynamics and the extrathermodynamic physicochemical properties or enthalpy-entropy compensation phenomena can be developed for the other major HPLC modes,... [Pg.220]
