摘要
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, 0.010 and 0.015 M). The average value of R or K determined, in the presence of pure HDABr micelles, using semi empirical kinetic (SEK) method appeared to be almost 2½-fold larger (R or K = 198) than that in the presence of mixed HDABr-CE micelles (R or K = 78). Rheological measurements indicated the existence of wormlike/twisted micelles and vesicle at 0.015 M pure HDABr, various [3,5-ClCHCONa], and 25 and 35℃ whereas there were evidence of only spherical micelles in the presence of mixed HDABr-CE ([HDABr] = 0.015 M and [CE] = 0.006 M) at both temperatures.
