Abstract

In this study, the mechanism of acid catalyzed hydrolysis of N-(4-substitutedaryl) succinimides in different acids was investigated. These acids are hydrochloric acid, perchloric acid and sulfuric acid, which were studied at 50.0 +/- 0.1 degrees C. Analyses of the results obtained with the entropy of activation, Excess Acidity treatment and substituent effect are consistent across the entire acid studied by an A-2 mechanism. The catalytic order of strong acids for the acid catalyzed hydrolysis of the compounds studied were as HCl > H2SO4 > HClO4 in the whole range of acidity. This order is characteristics for an A-2 mechanism.
