“…They have investigated the effects of catalyst loading, reactant molar ratios, initial water concentration and temperature on the reaction rate. Similar studies have also been done by Toor et al (2011) on the esterification of acetic acid with n-butanol and isobutanol over Amberlyst-15 catalyst, and by Akbay and Altiokka (2011) for the esterification reaction of acetic acid with n-amyl alcohol over Amberlyst-15, Amberlyst-36 and Amberlite IR-120 catalysts. For the above reaction of acetic acid with n-amyl alcohol, the effect of external and internal mass transfer resistances on the overall rate have also been studied.…”

Esterification of acetic acid with ethyl alcohol was carried out in the presence of a cation exchange resin. The resin used was Lewatit S1467, which is commercially available at a low cost and used commonly in the water treatment industry. The catalyst pretreated with HCl showed higher acetic acid conversions. The acidic cation exchange resin treated with HCl was examined for catalyst loading, reaction temperature and reusability. The highest acetic acid conversion of 58 % was observed for acetic acid to ethanol mole ratio of 1:1 at 335 K with a 5.4 % (w/w) catalyst loading. The experimental data were fitted with the pseudo homogeneous model, and the heterogeneous models Langmuir-Hinshelwood (LH) and EleyRideal (ER). LH model provided a better agreement with the experimental kinetic data, and the activation energy was found to be about 58 kJmol -1 .

“…1,2 In the early years, esterification reactions were carried out by using homogeneous catalysts like inorganic acid, metallic compounds, but they were less recommended due to separation, reuse, and disposal problems. [3][4][5] Hence, ionexchange resin catalysts have gained popularity as they are ecofriendly, noncorrosive, have good thermal stability and selectivity. [4][5][6] Due to their selective adsorption of reactants, surface characteristics, and swelling nature, these heterogeneous catalysts affect the equilibrium conversion.…”

The present research investigates the kinetics of ultrasound-assisted synthesis of dibutyl maleate using a heterogeneous catalyst (Amberlyst-15) in solvent-free system. Reaction parameters were optimized based on conversion by varying the various parameters such as n-butanol to maleic acid mole ratio, temperature, molecular sieves, catalyst loading, power, and duty cycle. Optimization of parameters resulted in 56.2% yield at 343 K, alcohol to acid mole ratio as 4:1, catalyst loading of 4%, molecular sieves of 4% with an ultrasound power input of 100 W with 60% duty cycle and 22 kHz frequency. In the presence of ultrasound, the reaction time reduced to 120 min in comparison with 240 min of the conventional process. The experimental kinetic data were correlated using Pseudo-Homogeneous model as well as heterogeneous models like Eley-Rideal model and Langmuir-Hinshelwood-Hougen-Watson (LHHW) model based on single as well as dual-site mechanisms. LHHW (reactants and products) model was found to be the best fit. The results proved that the reaction follows second-order kinetics. The activation energy of the reaction was calculated as 14.64 kJ/mol.

Production of cyclohexyl acetate by reaction between acetic acid and cyclohexanol using ion exchange catalyst Amberlyst - 15 presented in this work. Batch experiments were carried in batch reactor using variables such as agitation speed, catalyst size, temperature, mole ratio, catalyst loading, moisture content, catalyst reusability. Simulation also carried out using ACM. Activation energy found to be 10000 J/g.mole. Reactive chromatographic reactor is also used for process intensification. Results obtained from batch and reactive chromatographic reactors were compared. More conversion obtained in reactive chromatographic reactor as compared to batch reactor.
