(57) [Summary] (Modifications) [Problem] To select the incorporation of a compound to be separated into an aqueous phase composed of an aqueous solution of an inclusion complexing agent and the dissociation and recovery of the incorporated compound from the inclusion complexing agent. And a method for performing the method continuously and continuously. A reaction system having two or more liquid-liquid interfaces between an organic phase 4 as a raw material containing a compound to be separated and an aqueous solution of an inclusion complexing agent, and the aqueous phase and an organic phase as an extraction solvent. In the method, the compound is incorporated into the aqueous phase through formation of an inclusion complex between the compound and the inclusion complexing agent, and the organic phase 3 of the extraction solvent is separated through dissociation of the inclusion complex. The compound to be separated is taken into the inside. The above operation is performed using, for example, a square U-shaped tube 1 or an H-shaped tube with a bottom plate. As the inclusion complexing agent, for example, highly water-soluble branched cyclodextrins are preferable. |
