Synthesis and Evaluation of a Novel Hydrophilic 6,6′-Bis(1,2,4-triazin-3-yl)-2,2′-bipyridine Ligand for Separating Actinide(III) from Lanthanide(III)

Dedicated to Professor Steven Ley on the occasion of his 70^th birthday

Abstract

We report the synthesis and evaluation of a novel hydrophilic 6,6′-bis(1,2,4-triazin-3-yl)-2,2′-bipyridine (BTBP) ligand containing carboxylate groups as a selective aqueous complexing agent for the minor actinides over lanthanides. The novel ligand is able to complex and separate Am(III) from Eu(III) in alkaline solutions selectively.

Key words

BTBP - americium - separation factor - europium - N-heterocycle - used nuclear fuel - ligand

• 20 Synthesis of BTBP 11: The starting material 10 (0.40 g, 0.664 mmol) was dissolved in THF (90 mL) and a solution of NaOH (0.133 g, 5 equiv) in MeOH (30 mL) was added. The flask was heated under reflux for 3 h. The flask was allowed to cool to r.t. and the insoluble solid was filtered and washed successively with MeOH (40 mL), acetone (10 mL) and CH₂Cl₂ (10 mL). The solid was allowed to dry in air to afford the novel BTBP 11 as a yellow solid (0.35 g, 92%); mp above 300 °C (from MeOH). ¹H NMR (400.1 MHz, D₂O): δ = 8.22 (t, J = 7.9 Hz, 2 H, 4-H, 4′-H), 8.55 (dd, J = 7.9, 0.8 Hz, 2 H, 5-H, 5′-H), 8.57 (dd, J = 7.9, 0.8 Hz, 2 H, 3-H, 3′-H). ¹³C NMR (100.6 MHz, D₂O): δ = 124.9 (C-3, C-3′), 125.0 (C-5, C-5′), 139.6 (C-4, C-4′), 151.3 (2 × quat), 152.8 (2 × quat), 154.6 (2 × quat), 155.7 (2 × quat), 161.7 (2 × quat), 169.4 (2 × quat), 169.8 (2 × quat).

• 22 Under these conditions, extraction of Am(III) and Eu(III) into the organic phase by TODGA is more thermodynamically favored than back-extraction into the aqueous phase. The sulfonated ligands 4–6 are also unable to strip Am(III) from the organic phase at this pH.
