Abstract
Extraction of rare earth elements (REE) in 1,1,7-trihydrododecafluoroheptanol–water system with phosphoryl podands derived from diphosphonic acids of general formula 2-[(HO)(EtO)(O)P]-4-Et–C6H3–(OCH2CH2)n–OC6H3-4-Et-2-[P(O)(OEt)(OH)], n = 1–5 has been studied. Effect of medium acidity on REE extraction efficiency and selectivity has been studied. Crystal structure of 1,5-bis[2-(oxyethoxyphosphoryl)phenoxy]-3-oxapentane has been established by X-ray diffraction.
