Neptunium(V) disproportionation and cation–cation interactions in TBP/kerosene solvent

Keywords: Neptunium, Disproportionation, Kinetics, TBP, Near IR electronic absorption spectroscopy

In 30% TBP/OK Np(V) is unstable and disproportionates to Np(IV) and Np(VI). Np(V) readily coordinates to Np(IV) in solution to form a “cation–cation” complex by bonding through an axial oxo group on Np(V). The rate of disproportionation in 30% TBP/OK is >500 times that in aqueous solution.
