Abstract | dc.description.abstract | The critical micelle concentration, cmc, the dissociation degree, α, and the transfer free energy of anions Δμt° from water to micelle for different cetyltrimethylammonium salts CTAS (S = benzenesulfonate, OBSP-; tosylates, OTOS-; p-ethylbenzenesulfonate, OEBS-; and isopropylbenzenesulfonate, OIBS-) were determined. It was found that correlations exist between the cmc, α, and Δμt° values and that these correlations extend to CTAX salts (X = OH-, F-, Cl-, Br-, NO3 -). Viscosity measurements indicate that the more hydrophobic counterions induce a sphere-to-rod transition at lower concentrations. Partial molar volume changes of CTAOTOS also indicate a sphere-to-rod transition. © 1989 American Chemical Society. | |
