Cover Story: The synthesis of pentyl acetate from acetic acid and pentan-1-ol was studied using the commercial immobilized lipase Lipozyme®435 as a catalyst. The effects of some variables on the kinetics of the reaction were analysed, such as the initial concentration of acetic acid, the alcohol/acid molar ratio and the possible reuse of the enzyme. The kinetics data were determined by evaluating the existing acetic acid concentration during the established reaction time. The reactive process was in agreement with the so-called Bi-Bi Ping-Pong mechanism for enzymatic esterification, the most suitable modeling of which was achieved by performing an extension (considering the enzyme denaturation) of an initial simpler version of the model, which was also used. Comparison confirmed the improvement. View this paper
