Document Type and Number:
WIPO Patent Application WO/2019/187407
Kind Code:
A1
Abstract:
Provided is a novel use application of 5-methyl-2-hexanone. An extraction agent for metals contains 5-methyl-2-hexanone as an active ingredient, and can be used for the extraction of a chlorine complex or a fluorine complex of a metal capable of forming a chlorine complex or a fluorine complex from an aqueous solution of the chlorine complex of the metal or an aqueous solution of the fluorine complex of the metal.
