  摘要：

  Extraction of rare earth elements with bis(diphenylphosphorylmethyl) ethers of oligoethylene glycols Ph2P(O)CH2O(CH2CH2O)(n)CH2P(O)Ph-2 (L-n, n = 0-5) in 1,1,7-trihydrododecafluoroheptanol-water system with variable HNO3 concentration from 0.5 to 6 mol/L has been studied Complexes of Nd, Eu, Lu, and Er nitrates with L-0 and L-2 have been obtained. Crystal structures of [Ln(2)L(3)(o)(NO3)(6)]center dot xH(2)O (Ln = Nd, x = 1.99; Ln = Eu, x = 1; Ln = Er, x = 6.5; Ln = Lu, x = 6) and [LnL(2)(NO3)(3)(H2O)] (Ln = Nd, Er) have been studied by X-ray diffraction, IR spectroscopy, and thermogravimetry. Correlation between X-ray diffraction and extraction data has been revealed.

Carbamoyl-substituted dimethyl ethers were synthesized via transformation of phosphorylmethanols to phosphorylmethoxyacetic acids, followed by amidation. Symmetrical bisphosphoryl substituted dimethyl ethers were obtained by reaction of phosphorylmethanols with tosyl chloride in

  synthesized two kinds of polyphosphine polyoxides. The first one has ether bridge, and the second one shows PCP linkage. Complexation properties of these compounds towards minor actinides (Np, Pu and Am) have been evaluated from liquid-liquid extraction and from transport by supported liquid membranes. In decorporation experiment, some of the synthesized phosphonates exhibit in vivo good uranyl or neptunium
