Heat-sensitive compounds exhibitng a cloud point which can be used as extractants for the separation of metals in aqueous solution

摘要

The invention relates to a heat-sensitive compound having the property of being soluble in water below a critical temperature T_c and insoluble in water above this temperature T_c, this property being thermally reversible, characterized in that it comprises a first amphiphilic and thermally reversible part corresponding to one of the following formulae (I) and (II): in which i is an integer ranging from 1 to 20 and j is an integer ranging from 3 to 30. This compound can be used to extract a chemical entity, such as uranium.
