Abstract
The critical micelle concentration, surface potential, and degree of binding of counterions in aqueous micellar solutions of N-cetyl-N-methylmorpholinium bromide and its analog containing the hydroxyethyl moiety in the head group were determined using a complex of physicochemical methods. The aggregation behavior of these compounds was found to vary insignificantly, whereas the catalytic effect of the hydroxyethyl derivative on the hydrolysis of carboxylic acid esters more than an order of magnitude exceeds the effect of the non-functionalized surfactant. One of the reasons for this phenomenon can be an increase in the micropolarity in the chemical reaction zone detected by fluorescence spectroscopy.
