“…Furthermore, the residence time was varied by changing the length of the PFA capillary or the stainless steel capillary at constant total volumetric flow rate of the reaction mixture (0.156 mL/min) and reaction temperature (90°C), and its influence on the IL yield was studied (see Figure b). Interestingly, for the reaction temperature of 90°C the IL yield in Figure a was almost the same as that in Figure b when the residence time was not more than 50 s. The results in Figure indicated that the mass transport limitation was eliminated in this IL synthetic process and thus intrinsic reaction kinetics could be obtained within such a range of the residence time changed by the variation of the volumetric flow rate or the capillary length.…”

A tetraalkylammonium‐based ionic liquid (IL) was synthesized with diethyl sulphate and triethylamine in a capillary microreactor. Solvent‐free conditions coupled with microreactor technology greatly simplified the IL construction process. Optimization of process parameters (e.g., temperature, residence time, and inner diameter of capillary) was performed, and the maximum yield was 94% with the residence time of 300 s at 90°C. Interestingly, the obtained product could exist as a molten salt with low viscosity at a low melting point of 24.1°C. Key dimensionless groups such as Pe, Bo, and DaII numbers were calculated to account for the mass transport phenomena and reaction performance in this IL synthesis or to validate the reliability of the corresponding reaction kinetics study. Based on fast heat and mass transfer rates provided by the microreactor, intrinsic reaction kinetics could be obtained. Moreover, gold (III) extraction was remarkably improved by the application of the synthesized IL. © 2018 American Institute of Chemical Engineers AIChE J, 65: 1245–1255, 2019

“…On-chip EME can reduce the consumptions of sample and acceptor solution and be able to realize online analysis by continuously entering the sample solutions into channel and/or removing acceptor solutions . On-chip EME can efficiently improve sensitivity and enrichment performance as well as shorten operating time.…”

“…Due to their unique characteristics, the dropletbased microfluidic device has been widely applied in solvent extraction, nanoparticle fabrication, and biomedical assay [28][29][30][31]. Jahromi et al (2018) successfully extracted calcium ion in 98.55% extraction percentage with benzo-18-crown-6-ether within 1.5 s by using droplet-based microreactor system [32]. In our previous works, calix [4]arene derivatives were used as the extraction reagent due to its excellent ion discrimination ability.…”

By miniaturizing the reactor dimension, microfluidic devices are attracting world attention and starting the microfluidic era, especially in the chemistry field because they offer great advantages such as rapid processes, small amount of the required reagents, low risk, ease and accurate control, portable and possibility of online monitoring. Because of that, microfluidic devices have been massively investigated and applied for the real application of human life. This review summarizes the up-to-date microfluidic research works including continuous-flow, droplet-based, open-system, paper-based and digital microfluidic devices. The brief fabrication technique of those microfluidic devices, as well as their potential application for particles separation, solvent extraction, nanoparticle fabrication, qualitative and quantitative analysis, environmental monitoring, drug delivery, biochemical assay and so on, are discussed. Recent perspectives of the microfluidics as a lab-on-chip or micro total analysis system device and organ-on-chip are also introduced.
