Turanov, A. N. published the artcileExtraction of Rare Earth Elements(III) with Mixtures of 1-Phenyl-3-methyl-4-benzoyl-5-pyrazolone and 2-Phosphorylphenoxyacetamides, Computed Properties of 4551-69-3, the publication is Russian Journal of Inorganic Chemistry (2019), 64(3), 407-413, database is CAplus.
Extraction of rare earth element(III) (REE) ions from chloride solutions with mixtures of 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone and 2-phosphorylphenoxyacetamides in organic solvents has been studied. Observed considerable synergic effect is related to the formation of hydrophobic mixed-ligand REE(III) complexes. The stoichiometry of extracted complexes has been determined and extraction constants have been calculated Effect of aqueous phase composition, organic solvent nature, and 2-phosphorylphenoxyacetamide structure on the efficiency of REE(III) ions recovery into organic phase has been considered.
