Effect of surfactants on the kinetics of base-catalyzed hydrolysis of methyl, ethyl, isopropyl and n-butyl acetates

摘要

The velocity constants of base-catalyzed methyl, ethyl, isopropyl and n-butyl acetates in aqueous and micellar media are determined at different temperatures. The velocity constants in anionic and non-ionic media are higher than those in aqueous media, whereas the energy of activation are lower. The velocity constants for the alkaline hydrolysis of the esters vary in the order: kappa-methyl acetate > kappa-ethyl acetate > kappa-isopropyl acetate < kappa-n-butyl acetate.
