Abstract

The standard enthalpy of solubilization as well as the partition coefficient of 1-Pentanol between micelles and water have been determined in the whole composition range of two binary surfactant systems from microcalorimetry experiments. The free energy results compare favorably with partition coefficients deduced from a head-space gas-chromatographic technique. It is shown that the surfactant mixing of sodium decylsulfate+decyltrimethylammonium bromide (system I) or sodium dodecylsulfate+dodecylpolyoxyethylene(23) (system II) is unfavorable to micellar solubilization. The solubilization of 1-pentanol is a highly endothermic process for system (I) and only slightly endothermic for system (II). The regular solution approximation predicts qualitatively the standard free energy as well as the standard enthalpy data. These results illustrate a discussion on the limits as well as the usefulness of the regular solution approach as applied to these three-component systems using available solubilization results from the literature for hydrophobic solutes in binary micellar surfactant solutions.
