Interfacial Resistance in Solubilization Kinetics

Solubilization rates of oils in surfactant solutions and their relationship to mass transport in emulsions

“…At about the same time Shah and Neogi [24] measured rates of solubilization of toluene into SDS solutions. They found that solubilization rates per unit area were independent of time but increased with surfactant concentration until a limiting value was reached at high concentrations, i.e., behavior was qualitatively similar to that described above for decane although actual solubilization rates were severalfold higher, presumably owing to the higher solubility of toluene in water.…”

“…Pe is the Péclet number, as defined in Eq. (24). C is a constant with value in the range 2/3π < C <2/π.…”

Solubilization kinetics of soluble oils by an ionic surfactant

“…The latter are usually represented by c m , the micellar concentration. The data for the rate of solubilization of toluene by SDS from Shah and Neogi [2] are shown with new data for the solubilization rates of nitrobenzene by SDS in Fig. 1.…”

“…According to both Shah and Neogi [2] and Todorov et al [3], the controlling resistance for solubilization is an interfacial resistance. Later, Neogi [4] provided a detailed model for the case where c m is large and which showed the interfacial resistance used by Shah and Neogi [2] to be an effective resistance unlike * Corresponding author.…”
