| Abstract: | The influence of surface active agents on the hydrolysis of salicylic phenyl ester was examined. The results indicate that anionic and nonionic surfactants delay the hydrolytic decomposition of hydrophobic esters, whereas cationic solubilizing agents exhibit no stabilizing effect. On the basis of the changes in the adsorption spectra, the reactions rates, and the solubilizing actions, we conclude that the hydrophobic esters are localized in the core of the hydrocarbon chain of the surfactant micelles. The nature of the surfactants determines the extent of ester hydrolysis. |
