  • 2,9-dipyridyl-1,10-phenanthroline derivatives useful as actinide ligands, method for synthesizing same, and uses thereof
    Patent number: 9074266
    Abstract: The invention relates to novel compounds useful as ligands of actinides and which meet general formula (I) hereinafter: where: R1 and R2=H, a C1 to C12 hydrocarbon group, a monocyclic aryl or aryl-(C1 to C6)alkyl group; R3, R4, R5 and R6=H; a C1 to C12 hydrocarbon group; a monocyclic aryl or aryl-(C1 to C6)alkyl group; a —NR7R8 or —NR7COR8 group where R7=H, a C1 to C12 hydrocarbon group, a monocyclic aryl or aryl-(C1 to C6)alkyl group, while R8=a C1 to C12 hydrocarbon group, a monocyclic aryl or aryl-(C1 to C6)alkyl group; an —OR9 or —SR9 group where R9=a C1 to C12 hydrocarbon group, a monocyclic C6 aryl or aryl-(C1 to C6)alkyl group. A further subject of the invention is a method for synthesizing these compounds and the uses thereof.

  • Compounds useful as ligands of actinides, their synthesis and their uses
    Patent number: 8709129
    Abstract: The invention relates to novel compounds which are useful as ligands of actinides, to the synthesis of these compounds and to their uses. These compounds fit the general formula (I) hereafter: wherein R1 and R2, either identical or different, represent H, a linear or branched, saturated or unsaturated C1-C12 hydrocarbon group, a phenyl, benzyl, diphenyl or tolyl group; R3 represents H, a linear or branched, saturated or unsaturated C1-C12 hydrocarbon group, a phenyl, tolyl or linear or branched C1-C12 alkoxy group; while R4 represents H, a linear or branched, saturated or unsaturated C1-C12 hydrocarbon group, a phenyl or tolyl group. Field of applications: the processing of used nuclear fuels via a hydrometallurgical route.
