[EN] In this work the microwave effect of enhancing chemical reactions was applied to maleic
anhydride esterification with 2-ethylhexanol-1 catalyzed by p-toluene sulfonic acid. The
analysis of this reaction was simplified considering the industrial practice of withdrawn the
reaction water, which makes the whole reaction act as a pseudo irreversible one. A statistical
design of experiments was applied to determine an empirical chemical kinetics equation with
three levels of catalyst concentration and two levels related to the kind of heating
(microwave and conventional); six chemical kinetics equations (three for microwave heating
and three for conventional heating) were determined. A batch/plug flow simulation was done
and a spreadsheet developed for the reactor’s behavior. The most interesting result was the
confirmation of a synergic effect between microwaves and acid catalysis that accelerated
this esterification reaction, transforming it in a fast reaction.
