Solubilization of Hydrocarbons in Micelles

 

Molar solubilization ratio of hydrocarbons in 0.1 M solutions of sodium dodecyl sulfate at 25oC, plotted as a function of the volume – interfacial activity parameter (volume refers to that of the solubilizate and the interfacial activity is represented by the interfacial tension between the solubilizate and water). The five solubilizates are benzene, toluene, cyclohexane, n-hexane and n-decane, respectively. The experimental data are shown by circles while predictions of the model are represented by triangles.

 

 

Solubilization of binary hydrocarbon mixtures in surfactant micelles

 

Dependence of the molar solubilization ratio of benzene and hexane on the composition of the hydrocarbon phase in contact when binary mixtures of the two hydrocarbons are solubilized in 0.1 M solution of sodium dodecyl sulfate at 25oC . Points are experimental data while the continuous lines represent the predictions of the molecular theory.
