MICRO COUNTERCURRENT LIQUID FEEDER AND MICRO COUNTERCURRENT LIQUID-FEEDING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a micro countercurrent liquid feeder which can perform a mixing of fluids utilizing a molecular diffusion and shear with the ratio of each effect held constant, and at the same time, can control the reaction time of the mixing, and a micro countercurrent liquid-feeding method.;SOLUTION: The micro countercurrent liquid feeder 1 comprises a first introduction pipe 3A introducing an aqueous fluid 6, a second introduction pipe 3B introducing an organic solvent system fluid 7, exhaust pipes 4A and 4B discharging a mixed fluid 8 of the aqueous fluid 6 and the organic solvent system fluid 7, and a flow passage 20 in which the first introduction pipe is provided at one end 3A and the second introduction pipe 3B at the other end, a hydrophilic film 5 is provided to a wall surface which connects the first introduction pipe 3A and the first exhaust pipe 4A provided at a position facing the first introduction pipe 3A at the other end, and a wall surface which connects the second introduction pipe 3B and the exhaust pipe 4B provided at a position facing the second introduction pipe 3B at one end is constituted by a hydrophobic wall 20a, and which flows the aqueous fluid 6 and the organic solvent system fluid 7 alternately by countercurrent.;COPYRIGHT: (C)2011,JPO&INPIT
