A process for carrying out simultaneous liquid‐phase reaction and separation of desired products is described. It uses a fixed packed column of an admixture of a catalyst and an adsorbent that selectively removes a reaction byproduct from the reaction zone. The adsorbent is periodically regenerated using the concepts of liquid‐phase concentration swing adsorption. The integrated process allows production of multiple products at high purity with high conversions. For an endothermic reaction, the process permits much higher conversions of reactants to products at a substantially lower temperature than would be necessary by a plug‐flow reactor using the catalyst alone. The concept is demonstrated for hydrolysis of methyl acetate to produce acetic acid and methanol.
