摘要: In order to investigate the potential for process intensification, various reaction conditions were applied Kolbe–Schmitt synthesis starting from resorcinol. Different CO2 precursors such as aqueous potassium hydrogencarbonate, hydrogencarbonate-based ionic liquids, DIMCARB, or sc-CO2, application of microwave irradiation fast volumetric heating mixture, and effect harsh investigated. The experiments, carried out in conventional batch-wise well continuously operated microstructured reactors, aimed at development an environmentally benign preparation 2,4-dihydroxybenzoic acid. To provide decision support toward a green design, research-accompanying simplified life cycle assessment (SLCA) was performed throughout whole investigation. Following this approach, it found that convective methods oil bath electrical more beneficial than ir...
