Title:

METHOD FOR LOW-TEMPERATURE SELECTIVE FIXING OF HALOGENATED AROMATIC COMPOUND CONTAINED IN MEDIUM

Document Type and Number:

WIPO Patent Application WO/2015/146769

Kind Code:

A1

Abstract:

Provided is a method for: bringing into contact, at no more than 5°C, a selective fixing agent for halogenated aromatic compounds and an organic medium containing a halogenated aromatic compound, said selective fixing agent containing a porous cyclodextrin polymer that attractively interacts with the halogenated aromatic compound and wherein an alcohol, an aryl alcohol, or a phenyl alcohol has been caused to react with the terminal of the polymer produced by condensing cyclodextrin and an organic dibasic acid or a halogenated organic dibasic acid; fixing the halogenated aromatic compound contained in the organic medium to the porous cyclodextrin polymer that attractively interacts with the halogenated aromatic compound; and obtaining an organic medium that does not contain the halogenated aromatic compound.
