Abstract: The alkaline hydrolysis of aromatic and normal aliphatic acid esters has been studied at 25℃ in the micellar solutions of surfactants(DTAB,TTAB,CTAB,SDS,Brij-35,Triton X-100) with spectrophotometry and the method of thermokinetics in this paper.k1mand k2min micellar pseudophase have been calculated.The ratios of k2mto k2wor k1mto k1windicate that the alkaline hydrolysis of esters are inhibited by all researched micelles.We suppose the micropolarity of micelles can account for the inhbition of micelles.

Key words: Cationic surfactant micelle, Anionic surfactant micelle, Nonionic surfactant micelle, Alkaline hydrolysis of ester, Inhibition effect
