Abstract
AbstractThe esterification reaction between ethyl alcohol and acetic acid, catalysed by sulfuric acid, has been investigated over a wide range of temperatures and catalyst concentrations. A batch reactor was used to obtain operating data which may be applied to a process of simultaneous distillation with chemical reaction. The experiments were carried out at constant initial ethanol and acetic acid concentrations and the results were evaluated by a differential analysis method. The orders of the forward and reverse reactions were found to be 1 and 2, respectively. Reaction‐rate constants have been related to the reaction temperature for each catalyst concentration, and the frequency factors and the activation energies have been determined. Models representing the effects of temperature and catalyst concentration on the reaction rate constants have also been developed.
