BENZENE, TOLUENE, AND CYCLOHEXANE INCORPORATION INTO HEXADECYLTRIMETHYLAMMONIUM BROMIDE MICELLES - EFFECT ON THE BASIC HYDROLYSIS OF CRYSTAL VIOLET

Oil incorporation into CTAB micelles produces different effects on the basic hydrolysis of Crystal Violet. Benzene and toluene inhibit the reaction while cyclohexane produces a catalytic effect on the reaction. The highest amount of oil that can be incorporated into CTAB micelles in aqueous phase has been used and the physical properties of the micelle, such as the CMC and the fraction of neutralized micellar head groups, does not change significantly with the oil solubilization. The results have been analyzed on the basis of the pseudophase ion-exchange kinetic model and by considering ion distribution around the CTAB micelles according to the nonlinearized Poisson-Boltzmann equation. The fraction of micellar head groups neutralized and the critical micelle concentration have been obtained from conductivity measurements. © 1990.
