The scale-out core-annular liquid–liquid microextractor can further enhance the mass and heat transfer because of its increased total liquids contact area. In the current study, one such microextractor was employed, and four stretchable helix wires were placed in parallel and square arrangements for the aqueous stream to maintain the aqueous and solvent solution volume ratio at 1:10; these wires were surrounded by an organic solvent to ensure a stable aqueous–organic contact interface. A scale-out core-annular liquid–liquid microextractor was applied in 10 vol% acetone–toluene extract as a robust screening tool for process development; it demonstrated > 90 % extraction efficiency within 10 min and > 3 ml/hr production rate. These scale-out strategies revealed that the effective surface area–volume ratio applied in this study was more than 6 m− 1 and substantially mitigated insufficient production. |
