The present work reports a kinetic comparison between two resins made with different 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 com. resin (Amberlyst 36, 5.45 mmol g-1), but both presented similar efficiency in catalysis, probably due to the difference in crosslinking densities. The exptl. results explain the resins behavior and properties in detail (ion exchange capacities, swelling index and catalytic efficiency) and the kinetic models were compared utilizing the difference between the corrected Akaike Information Criterion (ΔAICc), Standard Deviation (s) and P-value (student t distribution). According to the results, the irreversible first order model had the best fit of the two models for the exptl. conditions studied for this work.
