Study of Cationic and Nonionic Mixed Micelles with NaBr and 3,5-ClCHCONa by Use of Probe Nucleophilic Reaction of Piperidine with Ionized Phenyl Salicylate.

Behaviors of cationic and nonionic mixed micelles in the form of hexadecyltrimethylammonium bromide (HDABr) and hexadecyltrimethylammonium bromide-Polyethylene glycol hexadecyl ether (CE), in the presence of inert salts (NaBr and 3,5-dichlorosodium benzoate), by the use of reaction probe between Pp and ionized PhSH (Pp = piperidine and PhSH = phenyl salicylate), has been reported in this work. The values of R (R denotes ion exchange constants obtained in the presence of micelles of different structural features) or K (K denotes ion exchange constants obtained in the presence of micelles of the same structural features) for 3,5-ClCHCO were almost the same at three different [HDABr] (0.006, 0.
