Technology Process of Difluorodioxouranium

There total 30 articles about Difluorodioxouranium which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 100.0%

Carbonyl fluoride (353-50-4) + uranium(VI) trioxide → uranyl fluoride (13536-84-0) + carbon dioxide (124-38-9,18923-20-1)

Guidance literature:

In neat (no solvent); slight excess over the stoich. amt. of COF2 required; reaction mixt. heated in a stainless steel or monel cylinder at 180°C for 45 h or at 210°C for 27 h;

Reference yield: 99.0%

2,3,3,3-tetrafluoro-2-(heptafluoropropoxy)propanoic acid (13252-13-6) + hydrogen fluoride (7664-39-3,12381-92-9,32057-09-3,74835-82-8) + uranyl(VI) acetate dihydrate → uranyl fluoride (13536-84-0)

Guidance literature:

In water; acid, aq. soln. of HF and uranyl acetate were mixed; volatiles were removed in vac.; IR;

Reference yield:

uranium oxide + hydrogen fluoride (7664-39-3,12381-92-9,32057-09-3,74835-82-8) → uranium(IV) tetrafluoride (10049-14-6) + uranyl fluoride (13536-84-0)

Guidance literature:

300°C;

upstream raw materials:

hydrogen fluoride

uranium hexafluoride

water

oxygen

Downstream raw materials:

uranium hexafluoride

chloryl fluoride

uranium(IV) tetrafluoride
