Abstract
The rate–surfactant concentration profiles for the reaction of the insecticide paraoxon with hydroxamate ions (R(C O)·NHO −, R = CH 3, R = C 6H 5, R = 2-HOC 6H 4) in aqueous solutions of cetyltrimethylammonium salts, CTAX (X − = Br −, Cl −, SO 3H −) have been measured at pH 11.0 at 30 °C. All these profiles are typical of micelle-assisted bimolecular reactions involving interfacial ion exchanges. The salicylhydroxymic acid–CTACl combination is most reactive.
