Alkyltrimethylammonium hydroxide surfactants (alkyl = dodecyl, tetradecyl, and hexadecyl) have been prepared, and their micellar properties investigated by means of electric conductivity, pH measurements, and fluorescence probing. With respect to the corresponding alkyltrimethylammonium bromide surfactants, the hydroxides form micelles at surfactant concentrations ca 2-fold larger, and their micelles have an ionization degree which is ca 3 times larger, whereas their aggregation number is ca 2-fold smaller. The relevance of these results for the understanding of the effect of cationic micelles on the rate of chemical reactions involving hydroxide ions is examined. (15 refs.)
