Technology Process of POTASSIUM FLUOROSULFITE

There total 1 articles about POTASSIUM FLUOROSULFITE 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: 85.0%

potassium fluoride (7789-23-3) + sulfur dioxide (7446-09-5,12143-17-8,89125-89-3) → potassium fluorosulphinate (14986-57-3)

Guidance literature:

In sulfur dioxide; absence of air and moisture; condensing excess SO2 onto metal fluoride at -196°C, warming in sealed tube to room temp., stirring for 1 d; evapn. (pumping at dry-ice temp.); yield depending on source of KF;

Reference yield: 75.0%

potassium fluorosulphinate (14986-57-3) + octachlorocyclotetraphosphazene (2950-45-0) → octafluorophosphazene (14700-00-6) + sulfur dioxide (7446-09-5,12143-17-8,89125-89-3)

Guidance literature:

In nitrobenzene; heating a soln. of (NPCl2)4 in C6H5NO2 with solid 90 % KSO2F on refluxing; react. starting at 80. degree.C under evolution of gas;; condensation of (NPCl2)3 and formed SO2 on cooling with ice-water; distn. in vac.;;

Reference yield: 64.5%

2,2,4,4,6,6-hexachloro-1,3,5-triaza-2,4,6-triphosphorine (940-71-6,16422-79-0) + potassium fluorosulphinate (14986-57-3) → hexafluorophosphazene (15599-91-4) + sulfur dioxide (7446-09-5,12143-17-8,89125-89-3)
