摘 要：The 1H NMR spectra of CTAB, SDS and Triton x-100 aqueous micellar solutions containing dimethyl phthalate have been determined. The results indicate that dimethyl phthalate in CTAB, SDS and niton x-100 micellar solutions at a low solubilizing concentration is adsorbed on the Ancelle-water interface. With the increase of solubilizing concentration, it is preferentially solubilised in both the palisade layer and hardly solubilised in the centre of the micellar core in CTAB micellar solution, and it is preferentially solubilised in both the palisade layer and the micellar core in SDS micellar solution while it is solubilised and uniformly distributed along the hydrocarbon chain of the surfactant in niton X-100 micellar solution.
