Preliminary experiments were run to assess the effects of internal and external mass transfer phenomena, and they were ruled out based upon the Weisz–Prater criterion. All rights reserved. Based upon a statistical experimental design, isothermal batch experiments were performed in the temperature range of 343.15–373.15 K, at three different catalyst loadings, and at different acid to alcohol mole ratios (1:1, 2:1 and 1:2). Amberlyst 15 was used as catalyst under kinetic regime.
