Technology Process of Teflic acid

There total 2 articles about Teflic acid 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: 68.0%

fluorosulfuryl hypofluorite (13536-85-1) + cesium pentafluoroorthotellurate → teflic acid (57458-27-2) + TeF5OF (83314-21-0) + tellurium hexafluoride (7783-80-4)

Guidance literature:

In neat (no solvent); byproducts: CsSO3F; CsTeF5O was evacuated and cooled to -196°C, FOSO2F (molar ratio 1.22:1) was added from vac. line, closed, warmed slowly to -78°C in liq. N2-CO2 slush bath, kept at -45°C for 9 d, cooled to -196°C; pumped off, sepd. by fractional condensation in traps (-78, -126 and -196°C);

Reference yield:

boron tris{pentafluoro-oxotellurate(VI)} (40934-88-1) → teflic acid (57458-27-2) + boric acid (11113-50-1,14635-83-7)
