Kinetics of the hydrolysis in 1 : 3 water–acetone of aliphatic esters having substituents in the alkyl group, catalysed by an acid resin or an acidic solution

Abstract

The efficiency of an acid resin for hydrolysis of esters substituted in the alkyl group, i.e., the ratio of the rate coefficient for hydrolysis with resin catalysts to the rate coefficient for hydrolysis in acidic solution, has been measured for a number of alkyl substituents. The efficiency has been shown to be related to the entropy of the substituent. Distribution coefficients have been measured for selected esters, and the results indicate that the variation in efficiency of the resin for esters containing cyclic and normal substituents is not due to differences in ester concentration in the vicinity of the resin matrix.
