  • Use of hydroxyiminoalkanoic acids as anti-nitrous agents in operations of reductive stripping of plutonium
    Patent number: 10354765
    Abstract: The use of hydroxyiminoalkanoic acids including at least four carbon atoms as anti-nitrous agents in operations of reductive stripping of plutonium. The invention may be useful in any method for processing spent nuclear fuels that includes one or more operations of reductive stripping of plutonium and, more particularly, in the PUREX method as implemented in modern nuclear fuel processing plants, as well as in processes derived therefrom.
    Type: Grant

  • Bifunctional compounds useful as ligands of uranium (VI), methods of synthesising same and uses thereof
    Patent number: 9441285
    Abstract: New compounds which meet general formula (I): where: m=0, 1 or 2; R1 and R2=a C6 to C12, straight-chain or branched, hydrocarbon group; R3=H, a C1 to C12, straight-chain or branched, hydrocarbon group, optionally comprising one or more heteroatoms; a C3 to C8 monocyclic hydrocarbon group, optionally comprising one or more heteroatoms, or a monocyclic (hetero)aryl group; or else R2 and R3 together form a —(CH2)n— group where n=1 to 4; R4=a C2 to C8, straight-chain or branched, hydrocarbon group, or a monocyclic aromatic group; R5=H, or a C1 to C12, straight-chain or branched, hydrocarbon group.
