Abstract: The new extractant based on dicyclohexano-14-crown-4 solution in 1,1,7-trihydrododecafluoroheptanol is proposed for the removal of lithium cations from the chloride media, such as reservoir waters. The stereoisomerism of the macrocyclic ligand is revealed to be a key factor determining the efficiency and selectivity of this system.

Keywords: dicyclohexano-14-crown-4, 1,1,7-trihydrododecafluoroheptanol, stereoisomerism, lithium extraction, selectivity.
