Abstract

The hydrolysis of acetic anhydride is a widely-studied liquid phase reaction studied since 1906. Different approaches have been used to study the kinetics of this reaction. Approaches used by researchers have involved the use of sophisticated experimental set-ups. In this work, the pH technique has been adopted which involves the use of a pH meter to monitor the hydrolysis reaction. Analysis of the hydrolysis reaction has been performed for water/acetone cosolvent systems over a range of temperatures and mole fractions. Eyring analysis was performed under isomole fraction conditions and activation enthalpy, entropy, and Gibbs free energy for hydrolysis of acetic anhydride have been determined.

The isomole fraction Eyring plots are linear, because, activation enthalpy and entropy are independent of temperature under these conditions. Activation free Gibbs energy increases with increasing temperature at a constant water mole fraction, while it decreases with increasing water mole fraction at constant temperature.
