Synthesis of organophosphorus ligands with a central oxygen atom and their applications in solvent extraction

Various structurally related glycolamide compounds were synthesised and evaluated by solvent extraction experiments for the separation of rare earth elements (REEs) from aqueous acid solutions using dodecane as the diluent. We describe herein the full synthesis of a family of bifunctional ligands with a central oxygen and focus our investigation on the effects of structural modification on the extraction efficiencies. The combination of an amide, a P[dbnd]O donor site, and a central oxygen in such a glycolamide ligand showed interesting extraction properties for heavy rare earth elements from phosphoric acid solutions.

AMIDATED PHOSPHORIC ACID ESTER COMPOUND, EXTRACTANT, AND EXTRACTION METHOD

PROBLEM TO BE SOLVED: To provide useful new compounds, particularly a compound that can be used as an extractant for extracting a valuable metal, such as a rare metal and a noble metal, or a toxic metal having high toxicity.SOLUTION: A compound represented by the general formula (1) or a salt thereof can be used as an extractant for extracting a metal element. (In the formula (1), R1, R2 and R3 represent hydrocarbon groups identical to or different from each other, provided that the total number of carbon atoms in the R1, R2 and R3 hydrocarbon groups is from 8 to 48.)SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPOandINPIT

Synthesis and evaluation of ligands with mixed amide and phosphonate, phosphinoxide, and phosphonothioate sites for An(III)/Ln(III) extraction

Various organophosphorus ligands with a combination of different donor sites were synthesized and evaluated by solvent extraction studies for the complexation of Am(iii)/Eu(iii). Among the ligands with a glycolamide backbone, those with mixed amide and P=O donor sites and a central oxygen or nitrogen atom showed a reasonable extraction of Am(iii) and Eu(iii). Ligands with a central oxygen atom exhibited selectivity towards Eu(iii), and those with a central nitrogen atom towards Am(iii). Ligands with P=S donor sites and a glycolamide backbone did not show any reasonable extraction. Amongst the ligands with a malonamide backbone, high extraction efficiency was observed for the ligand with electron-rich substituents on phosphorus, however, with almost no discrimination between Am(iii) and Eu(iii). The extraction efficiency of different ligands towards Eu(iii) was confirmed by microcalorimetry.
