“…Thus, to undertake the study of micellization of ionic surfactants in molten media, it is necessary to select such molten media that the above-mentioned difficulties can be overcome. Acetamide melt has attracted the attention of many molten salt chemists because of its ability to act as an excellent polar solvent and to form room-temperature molten salts on mixing with inorganic salts. − Recently, Akhter 3 reported that surfactants do micellize in acetamide melt. In the present work specific conductances of sodium dodecyl sulfate (SDS) and cetylpyridinium chloride (CPC) in acetamide melt were measured at 89 °C with a view to estimate their micellization parameters in this molten medium by using the mixed-electrolyte model reported recently by Shanks and Franses .…”

Electrical conductances of solutions of sodium dodecyl sulfate (SDS) and cetylpyridinium chloride (CPC) in acetamide melt were measured at 89°C as a function of concentration. The dependence of molal conductance of SDS and CPC on concentration has been compared with that of normal electrolytes in acetamide melt. Both SDS and CPC are found to micellize in acetamide melt. A mixed electrolyte model has been used to compute the micellization parameters, viz., critical micelle concentration, aggregation number, and counterion binding constant, from the conductance data. Surface potentials of the micelles were computed by solving the nonlinearized Poisson-Boltzmann equation. The free energy terms for micellization were also evaluated.
