The production of methyl decanoate (MeDC) through esteriﬁcation of decanoic acid (DeC) with methanol by reactive distillation is operationally challenging and energy-intensive due to the complicated behavior of the reaction system and the diﬃculty of retaining the reactants together in the reaction region. Methanol being the lightest component in the mixture can separate itself from the reactant DeC as the distillation proceeds which will cause a massive reduction in the conversion of DeC utilizing either a batch or continuous distillation process.Aiming to overcome this type of the potential problem, novel integrated divided-wall batch reactive distillation conﬁguration (i-DWBD) with recycling from the distillate tank is established in this study and is examined in detail. This study has clearly demonstrated that the integrated divided-wall batch reactive distillation column (i-DWBD) is superior to the traditional conventional batch distillation (CBD) and both the divided-wall (DWBD),and split reﬂux divided-wall (sr-DWBD) batch reactive distillation conﬁgurations in terms of maximum achievable purity of MeDC and higher conversion of DeC into MeDC. In addition, signiﬁcant batch time and energy savings are possible when the i-DWBD is operated in multi-reﬂux mode.
