| Resumo | |
The effect of strong acid (hydrochloric acid) catalyst and salts (sodium chloride and potassium chloride) on the kinetics of the hydrolysis of acetic anhydride was studied using a simple isoperibolic calorimetric technique. The apparent second-order rate constant was observed to increase linearly with the increase in the strong acid concentration, suggesting the occurrence of a non-catalytic and an acid-catalyzed reaction route. The kinetic parameters for the non-catalytic route and for the acid-catalyzed route were determined. The effect of salt concentration causes a decrease in the effective rate constant over the range of variables studied. Sodium and potassium chloride presented practically the same negative effect on the hydrolysis kinetics. (C) 2020 Institution of Chemical Engineers. Published by Elsevier B.V. All rights reserved.
