Reactive and non-reactive counterion surfactants in water and aqueous acetonitrile

Rates of hydrolysis of hydroxamic acids with perfluorooctanoic acid as a reactive counterion surfactant and also with sodium sulfonate surfactants plus HCl have been determined in both water and aqueous acetonitrile solvents. The pseudophase ion exchange model satisfactorily explains the micellar effects for both the reactive and non-reactive counterion surfactants in both solvent systems.
