Abstract
Abstract Neptunium dioxide and tetrafluoride are converted in essentially quantitative yield to volatile neptunium hexafluoride by dioxygen difluoride (O2F2), both in gas–solid reactions at ambient temperatures and in liquid anhydrous hydrogen fluoride at −78°C. Neptunium dioxydifluoride was identified by Raman spectroscopy as a dominant reaction intermediate in the neptunium dioxide reaction. Direct reaction of NpF4 with liquid O2F2 resulted in violent decomposition of O2F2 with little or no conversion to NpF6. These reaction temperatures contrast markedly with the elevated temperatures (above 200°C) required for NpF6 generation using elemental fluorine or halo...
