QUELATING AGENTS FOR LANTANIDE EXTRACTION BY METHOD OF TEMPERATURE-INDUCED PHASE SEPARATION Russian patent published in 2009 - IPC C01F17/00 C07F9/53

Abstract RU 2364573 C1

FIELD: chemistry.

SUBSTANCE: invention relates to phosphine oxides, which can be used as quelating agents for extraction of lantanides from acid water solutions, and can be applied for ecological monitoring of sewage waters in regions of processing and burial of radioactive wastes. Efficient extraction of lanthanum, gadolinium and lutetium from highly-acid water solutions by method of temperature-induced phase separation is achieved by application of phosphine oxides of general formula , where: R¹=C₄H₉, R²=C₆H₅, R=C₆H₁₃, R²=C₆H₅, R¹=C₈H₁₇, R²=C₆H₅, R¹=C₆H₅, R²=C₄H₉ as quelating agents.

EFFECT: elaboration of novel efficient extractants of lanthanides.
