METHOD OF PRODUCING URANIUM OXIDES FROM URANIUM TETRAFLUORIDE Russian patent published in 2011 - IPC C01G43/01

Abstract RU 2414428 C1

FIELD: chemistry.

SUBSTANCE: invention can be used to convert depleted uranium tetrafluoride. Uranium tetrafluoride is brought into contact with ether of formula R₂O in counterflow conditions, where R denotes H, CH₃, C₂H₅, C₃H₇, C₄H₉ at temperature 450-550°C for 15-20 minutes in molar ratio UF₄ / ether between 1-2.64 and 1-25.08.

EFFECT: invention enables to obtain uranium oxides which are not contaminated with fluorine.
