Zainol, Muzakkir Mohammad published the artcileBio-fuel additive synthesized from levulinic acid using ionic liquid-furfural based carbon catalyst: Kinetic, thermodynamic and mechanism studies, Formula: C7H12O3, the main research area is biofuel levulinic acid ionic liquid carbon catalyst thermodn kinetics.
The Et levulinate is one of promising platform chem. from biomass and commonly involved the esterification reaction of levulinic acid. The reactions are extensively focussed on the catalytic performance by various catalysts and presented limited work on the kinetic, thermodn. and mechanism study for heterogeneous catalyst reaction. To fill this gap, the reaction anal. over a new ionic liquid-furfural carbon catalyst has been investigated in this work. The math. equations were derived to determine the kinetic-thermodn. parameters, and proposed suitable mechanism for the reaction. Pseudo-first order model presents high correlation coefficient and accuracy with the reaction rate constant of 0.0037-0.0127 min-1 and Ea = 17.3 kJ/mol. The reaction is endothermic and non-spontaneous with ordered system at transition state. The proposed combined nucleophilic substitution and Eley-Rideal mechanism is comprised of SN2 steps and heterogeneous catalytic reaction. The results provide insights on the reaction for future designing and scaling-up the esterification process.
