Abstract
The alkaline hydrolysis of aromatic and normal aliphatic acid eaters h as been studied at 25 degrees C in the micellar solutions of surfactan ts (DTAB, TTAB, CTAB, SDS, Brij-35, Triton X-100) with spectrophotomet ry and the method of thermokinetics in this paper, k(1m) and k(2m) in micellar pseudophase have been calculated. The ratios of k(2m) to k(2w ) or K-1m to K-1w indicate that the alkaline hydrolysis of esters are inhibited by all researched micelles. We suppose the micropolarity of micelles can account for the inhibition of micelles.
