Sažetak

The kinetics of the esterification of n-butanol with acetic acid
have been studied in a batch and in a tubular reactor. The best
model for obtaining the esterification rate with a partially wet ion
exchanger (270/o water contents) is obtained by assuming a pseudohomogeneous
system, while the kinetics of dry ion exchangers is
best represented by a model derived from assumptions based on a
heterogeneous system.
A separate study of the induction period in a tubular reactor
shows the considerable influence of the water content on reaction
kinetics. This is manifested by a change of the catalytic activity
during the reaction. Change of the catalytic activity can lead to
erroneous interpretation of experimental results and to derivations
of inadequate kinetic expression. It is shown that change of
ion exchanger activity in the induction period is caused by diffusion
of reactants into resin particle.
