Abstract
Sodium-N-dodecanoylphenylalaninate, an anionic amino acid surfactant (AAS) has been synthesized and characterized by spectroscopy and tensiometry. The kinetics of alkaline hydrolysis of tris(2,2′-bipyridine)iron(II) complex has been studied in presence of AAS and SDS in the temperature range of 303–318K. Both the surfactants have an inhibitory effect on the rate, particularly below the CMC of the surfactants. The inhibitory effect of the surfactants has been accounted for by the association/binding of the surfactant molecule with the substrate. The activation parameters and the binding constants at different temperatures were determined from the temperature effect. The results in terms of different transition points, binding of the substrate-bound surfactant aggregates & free micelles, the standard enthalpy & entropy of activation, binding constants & interaction of both surfactants, and so forth have been explained. The results have been rationalized in terms of an interaction model.
