Abstract : The solubilization of diethyl ether, acetone, npropylamine, and methyl acetate by sodium and magnesium dinonylnaphthalene sulfonates in toluene solution was studied by gas-liquid chromatography. Results are compared with data for the solubilization of methanol and acetic acid. Of the solubilizates studied, all were less extensively solubilized than methanol. Within the scope of the data, n-propylamine and acetic acid were solubilized approximately equally by the magnesium soap, but the sodium soap solubilized the acid more vigorously than the amine. The ether and detone were only faintly solubilized and the ester occupied an intermediate position. The data are consistent with conclusions derived from earlier studies of micelle formation and solubilization by the same soaps. At very dilute concentrations of solubilizate, the cation of the soap controls the interaction, but with increasing concentrations, after the coordinating tendency of the cation is satisfied, the anion is the effective moiety.
