Esterification of n-Butanol with Acetic Acid Catalyzed by a Cation Exchange Resin

The kinetic of the esterification of n-butanol with acetic acid have been studied in a batch and in tubular reactor. The best model for obtaining the esterification rate with a partially wet ion exchanger is obtained assuming a pseudohomogeneous system, whil the kinetic of dry ion exchanges is best represented by a model derived from assumption based on a heterogeneous system. A separate study of the induction period in tubular reactor shows considerable influence of the water content on the reaction kinetics. This is manifested by a change of the catalytic activity during reaction. Change of the catalytic activity can lead to erroneus interpretation of experimental results and to derivations of inadequate kinetic expression. It ois shown that the change of ion exchanger activity in the induction period is caused by diffusion of reactant into resin particle
