METHOD OF CONTINUOUSLY AND SELECTIVELY SEPARATING CLATHRATE AND APPARATUS THEREFOR

Document Type and Number:

WIPO Patent Application WO/2001/064606

Kind Code:

A1

Abstract:

In a reaction system having at least two liquid-liquid interfaces between an aqueous phase, which comprises an organic phase of a material containing the compound to be separated and an aqueous solution of a clathrate complexing agent, and an organic phase comprising an extraction solvent, the above compound is incorporated into the aqueous phase via the formation of a clathrate complex of the compound and the above clathrate complexing agent and, at the same time, the compound to be separated is incorporated into the organic phase of the extraction solvent via the dissociation of the above-described clathrate complex. The procedures as described above are carried out by using, for example, a square U-shape tube or an H-shape tube provided with a bottom plate. It is preferable to use, for example, highly water-soluble branched cyclodextrins as the clathrate complexing agent.
