Uranyl peroxide species and solid state materials are important phases within the nuclear fuel cycle and have been extensively investigated within aqueous solutions.  Formation of peroxide in non-aqueous conditions is less understood, but also has important implications in the separation of waste products using liquid-liquid extractions.  In this presentation, we will discuss current efforts to understand in-situ peroxide generation in organic solvents and the formation of uranyl peroxide coordination complexes and larger macromolecules.  In particular, we will focus on the autoxidation of benzaldehyde in benzyl alcohol solutions in the presence of uranyl and phosphonate ligands. Raman spectroscopy of the solution phase provides our mechanistic understanding of the reaction pathway and confirms consistent levels of peroxide generated in-situ over an extended period of time.
