Hydrophobic Organic Liquid Composition For The Selective Extraction Of A Lithium Salt

Abstract: The present invention relates to a hydrophobic organic liquid composition for the selective extraction of a di-ionic lithium salt comprising a lithium cation and an anion complementary to the lithium cation, chosen in particular from Cl, I, Br, CN, MK and HCO 3, from a lithium-rich brine to be treated, said composition comprising (A) at least one compound extracting the lithium cation, chosen from the compounds of formula: (I) in which R1, R2, R3, R4, R5 and R6 are as defined in the description; (B) at least one organic, protic and hydrophobic compound solvating the anion complementary to the lithium cation; and (C) at least one hydrophobic polar organic diluent having a flash point at atmospheric pressure greater than 60°C, preferably greater than 75°C, more preferably greater than 90°C.
