Technology Process of Tetrafluorogermane

There total 35 articles about Tetrafluorogermane 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: 87.0%

barium germanium fluoride → barium fluoride + germanium tetrafluoride (7783-58-6)

Guidance literature:

In neat (no solvent); heating BaGeF6 in a quartz tube; the formation of GeF4 begins at 500 °C; fast reaction at 700 °C; caution : GeF4 reacting with Hg (vac. apparatus);; condensing GeF4 with liquid air; fractionating under vac.; transition temp.: 104 °C;;

Reference yield: 84.0%

Carbonyl fluoride (353-50-4) + germanium dioxide → carbon dioxide (124-38-9,18923-20-1) + germanium tetrafluoride (7783-58-6)

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 100°C for 24 h;

Reference yield: 75.0%

germanium (7440-56-4) + trifluoroamine oxide (13847-65-9,57526-95-1,478286-98-5) → germanium tetrafluoride (7783-58-6)

Guidance literature:

In neat (no solvent); cylinder fiited with dry powdered element, NF3O condensed into cylinder at -196°C, mixt. heated at 180°C for 16h; not isolated, monitored by NMR, IR;

upstream raw materials:
