Abstract :The resins in their acidic form are often used to catalyze esterification reaction in place of mineral acids. Deactivation of the catalyst, in heterogeneous catalytic reactions are often important to industry. In this study, the deactivation of Amberlite IR-120 in an esterification reaction was investigated.  Data on the esterification of acetic acid with isobutanol have been obtained from heterogeneously catalyzed reactions using a stirred batch reactor in dioxane. The reaction has been carried out in the presence of the cation-exchange resin in the H+ form, Amberlite IR-120, at temperature ranging from 318 to 368 K.  It was observed that there is a negligible catalyst deactivation in 25 days of usage
