A prototype continuous-flow liquidâliquid extraction system is reported. By harnessing several open-source software libraries, a computer control script was written using the Python programming language. Using a âcomputer-visionâ approach, this allowed the computer to monitor the interface level between the organic and aqueous phases using a simple webcam setup and (by dynamically controlling pump flow rate) to keep this interface within defined limits. The system enabled the efficient âinlineâ extraction of excess reagent in hydrazone formations, dithiane formations and epoxidations. The initial results of dispersion measurement are also presented.
