“…However, in contrast to the above-mentioned advantages, there are several constraints that limit the successful application of RD, such as complex design, difficult scale-up and advanced process control (Schoenmakers and Bessling, 2003;Sundmacher and Hoffmann, 1996). Nevertheless, RD has been industrially applied for certain types of chemical-equilibrium limited reactions, the most important being esterifications (Agreda et al, 1990;Keller et al, 2011b;Schmitt et al, 2004), transesterifications (Steinigeweg et al, 2004) and etherifications (González-Rugerio et al, 2012;Sundmacher and Hoffmann, 1996).…”

Reactive distillation (RD) has already demonstrated its potential to significantly increase reactant conversion and the purity of the target product. Our work focuses on the application of RD to reaction systems that feature more than one main reaction. In such multiple-reaction systems, the application of RD would enhance not only the reactant conversion but also the selectivity of the target product. The potential of RD to improve the product selectivity of multiple-reaction systems has not yet been fully exploited because of a shortage of available comprehensive experimental and theoretical studies. In the present article, we want to theoretically identify the full potential of RD technology in multiple-reaction systems by performing a detailed optimisation study. An evolutionary algorithm was applied and the obtained results were compared with those of a conventional stirred tank reactor to quantify the potential of RD to improve the target product selectivity of multiple-reaction systems. The consecutive transesterification of dimethyl carbonate with ethanol to form ethyl methyl carbonate and diethyl carbonate was used as a case study.

“…The industrial application of chromatographic separation is reported in theˆeld of chiral and bioseparations 11) . The esteriˆcation of acetic with n-hexanol was carried out in jacketed batch reactor 12,13) and in reactive distillation column 14) The objective of the present work is to optimise the synthesis of n-hexyl acetate (a fruity smelling ‰uid used as a ‰avouring agent or in perfumes) in a batch chromatographic reactor, which has not been reported in the literature till date.…”

Laboratory scale batch chromatographic reactor experiments were carried for the esteriˆcation of acetic acid with nhexanol to synthesise a value added ester, namely n-hexyl acetate in the presence of an ion exchange resin catalyst, Purolite CT-124. The eŠect of various parameters such as solvent ‰ow rates in the regeneration step, amount of reactants in the reaction step and reaction step time was studied for optimisation of the reaction condition in a batch chromatographic reactor. This information would be useful for the design, operation and optimisation of n-hexyl acetate synthesis in a continuous chromatographic reactor.
