Abstract or Introduction

The micellar properties of cationic dodecyltrimethylammonium chloride (DTAC) in aqueous media in the presence of 15-crown-5ether (CR) have been investigated by conductivity measurements over the temperature range 288.15-308.15 K. The results of the ternary DTAC/CR/W system were analysed in comparison with the reported results of binary DTAC/W system. The critical aggregation concentration (cac) and degree of ionization of the micelles were determined from the conductivity measurements at different temperatures. Thermodynamic parameters for the micellar system were estimated by applying the charged pseudo-phase separation model. Micellisation was found to be spontaneous and entropy-driven.
