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.

“…The methods for preparing IBOAC were always the focal point in commercial production because of its good performance as a solvent and pleasant odor. In the 1990s, some researchers had paid close attention to the synthesis methods. , Nowadays, the most common way to synthesize IBOAC is esterification. − For instance, the reaction of isobutanol (IBOH) and acetic acid or acetic anhydride can be conducted with strong acid as the catalyst. Although for the moment the technology for preparing IBOAC via the esterification reaction has been mature, it is worth taking account of another perfect option, transesterification, for preparing IBOAC (eq ).…”

The reaction kinetic and chemical equilibrium for the production of isobutyl acetate via transesterification between methyl acetate and isobutanol is investigated as the presence of catalyst Amberlyst-15. The experimental kinetic parameters are obtained by the application of the Arrhenius equation. The novel reactive dividing-wall distillation process for production of isobutyl acetate via transesterification is proposed on the basis of a conventional reactive distillation process. The reactive dividing-wall distillation process is simulated and investigated for saving more energy and reducing the total annual cost (TAC) of the process. The energy consumption and the TAC of the reactive dividing-wall distillation process can be reduced by 26.40% and 18.25%, respectively, in comparison with the conventional RD process.

The reaction kinetics of transesterification of methyl acetate with isobutanol catalyzed by ionic liquid 1-sulfobutyl-3-methylimidazolium hydrogensulfate was measured. The reaction kinetic data were correlated by the ideal homogeneous model and nonideal homogeneous model, and the corresponding kinetic parameters were obtained. A reactive and extractive distillation (RED) process was proposed to conduct the transesterification, and the process was simulated based on the analysis of vapor− liquid equilibrium and reactive residue curve maps. High purities of products and high conversions of reactants can be achieved by the RED process. Effects of operating and structural parameters of the RED column and entrainer recovery column were investigated. Moreover, a lab-scale RED experiment was conducted to verify the reliability of the simulation process, and the simulation results agreed well with the experiment.
