Effect of alcohols on the properties of micellar systems. Part 3. Elastic and quasielastic light scattering study
In this work, a systematic investigation was reported of the effect linear 1-alcohols (propanol, butanol, and pentanol) on the properties of micellar solutions of tetradecyltrimethylammonium bromide (TTAB) in H/sub 2/O-0.1 M KBr by means of elastic and quasielastic light scattering methods. These measurements have been performed to obtain the micelle molecular weights and diffusion coefficients, in presence of alcohol, both at the critical micelle concentration (CMC) and at C > CMC. The results have confirmed previous observations and have yielded original information on the behavior of micellar solutions when salt, which reduces intermicellar electrostatic repulsions, and alcohol are present simultaneously in the system. In particular, the change of the micellar molecular weight with pentanol concentration is rationalized in terms of alcohol solubilization by the micelles and changes of size and shape of the micelles. 28 references.
