Technology Process of POTASSIUM DIFLUOROPHOSPHATE

There total 3 articles about POTASSIUM DIFLUOROPHOSPHATE 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:

difluorophosphoric acid anhydride (14456-60-1) → trifluorophosphoric acid (13478-20-1) + potassium difluorophosphate (13767-90-3)

Guidance literature:

With potassium fluorosulphinate; In not given; byproducts: SO2;

Reference yield:

potassium hydrogenfluoride (1279123-63-5) + trichlorophosphate (10025-87-3,12599-09-6,63736-95-8,39380-77-3) → potassium hexafluorophosphate (17084-13-8) + potassium difluorophosphate (13767-90-3)

Guidance literature:

In acetonitrile; byproducts: KCl, HCl; a mixt. of KHF2 and POCl3 (equal amts.) in MeCN was stirred for 24 h at room temp.;; the solvent was distd. off, the solid residue agitated with EtOH, KPF6 pptd. by addn. of ether; after filtration, the filtrate was evapd. to yield KPO2F2; elem. anal.;

Reference yield:

potassium hydrogenfluoride (1279123-63-5) + phosphorus(V) oxybromide (7789-59-5) → potassium hexafluorophosphate (17084-13-8) + potassium difluorophosphate (13767-90-3)

Guidance literature:

In acetonitrile; byproducts: KBr, HBr; a mixt. of KHF2 and POBr3 (equal amts.) in MeCN was stirred for 24 h at room temp.;; the solvent was distd. off, the solid residue agitated with EtOH, KPF6 pptd. by addn. of ether; after filtration, the filtrate was evapd. to yield KPO2F2; elem. anal.;
