“…The NRTL binary interaction parameters ( B ij ) and nonrandomness parameters (α ij ) are listed in the Table . The NRTL parameters for methyl acetate and isobutyl acetate were obtained from Wang et al The NRTL parameters for methanol and o -xylene, as well as methyl acetate and o -xylene were obtained from Jiménez et al and Costa-Lopez et al, respectively. The NRTL parameters of methyl acetate and isobutanol, as well as isobutyl acetate and methanol were obtained by regression of the experimental vapor–liquid equilibrium (VLE) data in the literature. , The parameters for isobutyl acetate and o -xylene were estimated by the modified UNIFAC model.…”

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.
