Abstract—Kinetic study of the esterification of maleic acid
with ethanol has been carried out over cation exchange resin
Indion 730, Indion 225H, AmberliteIR120, Amberlyst 35 wet.
Indion 730 has shown the higher conversion of maleic acid than
other catalyst. Effect of various parameters such as speed of
agitation (600- 1000 rpm), particle size (0.172 – 0.834 mm), mole
ratio (maleic acid to ethanol, 1:4 – 1:10), catalyst loading
(50-120 kg/m3 of reactant volume), temperature (323-353 K) has
been studied. A psudo homogeneous model has been applied to
validate the experimental data at different temperature and
activation energy was found to be 12.54 kcal/mol.
Index Terms—Activation energy, esterification, indion 730,
kinetics.
