摘要

研究了不同酸对N-(4-取代二烷基)琥珀酰亚胺的酸催化水解机理。这些酸是盐酸、高氯酸和硫酸,分别在50.0℃和177℃、0.1℃和176℃进行了研究。活化熵、超酸性处理和取代基效应的分析结果在A-2机制研究的整个酸中是一致的。强酸对所研究化合物酸催化水解的催化顺序为HCl和gt;硫酸andgt;HClO4在整个酸度范围内。这种顺序是A-2机构的特征。

Kinetics and Mechanisms of Acid-Catalyzed Hydrolysis of Some N-(4-Substitutedaryl) Succinimide Compounds
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 50.0and#177;0.1and#176;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 andgt; H2SO4 andgt; HClO4 in the whole range of acidity. This order is characteristics for an A–2 mechanism.
