Technology Process of Tantalum pentachloride

There total 71 articles about Tantalum pentachloride 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: 94.0%

tantalum(V) oxide + chlorine (7782-50-5) → tantalum pentachloride (7721-01-9)

Guidance literature:

With tetrachloromethane; pyrographite; heating Ta2O5 and powdered charcoal in Cl2 stream saturated with CCl4 at 650 °C for 4 h;

Reference yield: 90.0%

aluminium trichloride (7446-70-0) + potassium heptafluorotantalate → tantalum pentachloride (7721-01-9)

Guidance literature:

240 °C; sublimation;

Reference yield: 90.0%

potassium heptafluorotantalate + lithium chloride → tantalum pentachloride (7721-01-9)

Guidance literature:

750 °C for 1 h in inert gas, molar ratio of K2TaF4:chloride = 1:2;

upstream raw materials:

sulfur dichloride

chlorine

phosgene

disulfur dichloride

Downstream raw materials:

tributyltin chloride
