Deprotonation of 5-Nitroindole in Micellized Cetyltrimethylammonium Bromide and Hydroxide

Article abstract of DOI:10.1021/j150643a040

The fraction, f, of deprotonation of 5-nitroindole (BH) in cetyltrimethylammonium bromide (CTABr) and NaOH goes through maxima with .In CTAOH micelles f increases smoothly with , even when the indicator is fully micellar bound, and is increased by added NaOH.These variations of f follow the concentrations of BH and OH^- in the cationic micelles and the basicity constant in the micellar pseudophase is smaller than in water by a factor of ca. 5.
