Abstract : The behavior and state of aggregation of barium dinonylnaphthalene sulfonate in toluene, toluene-methanol and methanol solutions were studied by ultracentrifugation and viscometry. The aggregation number of its micelles is substantially reduced at free methanol mole fractions of 0.03 and less. In pure methanol, micelles do not exist, and the monomers dissociate ionically. Results of the investigation supplement an earlier observation that the solubilization of methanol diminishes the size of sulfonate and carboxylate micelles in nonaqueous solvents. (Author)
