• Abstract: The present work reports a kinetic comparison between two resins made with diferent cross-linkers, Amberlyst 36 and PS-TMPTA. The latter was synthesized in this study. Both resins were used as catalysts in glycerol acetylation in a batch reactor at 80 and 90 °C, with 5 and 10 g L−1 of catalyst concentration under a molar ratio 4:1 of acetic acid/glycerol. The synthesized resin (PS-TMPTA) presented low ion exchange capacity (1.5 mmol g−1) compared to the commercial resin (Amberlyst 36, 5.45 mmol g−1), but both presented similar efciency in catalysis, probably due to the diference in cross-linking densities. The experimental results explain the resins’ behavior and properties in detail (ion exchange capacities, swelling index and catalytic efciency) and the kinetic models were compared utilizing the diference between the corrected Akaike Information Criterion (ΔAICc), Standard Deviation (s) and P-value (student t distribution). According to the results, the irreversible frst order model had the best ft of the two models for the experimental conditions studied for this work.
