Abstract
Micelle formation by n-alkyl(2-hydroxyethyl)dimethylammonium bromides in ch loroform was studied by dielcometric titration and kinetic method. Increase in the length of the hydrocarbon chain leads to reduced critical micelle c oncentration. The region of structural reorganization of micelles was deter mined. n-Alkyl(2-hydroxyethyl)dimethylammonium bromides catalyze phosphoryl ation of tetrakis(dimethylaminomethyl)calixresorcin[4]arene. The catalytic activity of micelles depends on the hydrophobic properties and concentratio n of the surface-active substance, as well as on structural features of its aggregates.
