Fluorine fluorosulfate is an inorganic compound of fluorine, oxygen, and sulfur with the chemical formula F
2O
3S.
Synthesis
The compound can be prepared by the reaction of sulfur trioxide and fluorine at a temperature of 200 °C:[1]
- SO
3 + F
2 → FOSO
2F
- SO
Also, a reaction of peroxydisulfuryl difluoride with fluorine.[2]
Physical characteristics
The compound is a strong oxidizing agent that is also potentially explosive.[3]
At 200 °C the compound decomposes without explosion.[4]
Chemical properties
The compound reacts with bases to form the fluorosulfonate anion, the fluoride ion, water, and oxygen:[5]
- FSO
3F + 2 H−
→ SO
3F−
+ F−
+ H
2O + 1/
2O
2
- FSO
It reacts with potassium iodide to form potassium fluorosulfonate, potassium fluoride, and iodine:[5]
- FSO
3F + 2 KI → KSO
3F + KF + I
2
- FSO
Fluorine fluorosulfate reacts with SSF
2, SeF
4, AsF
3, and MoF
5 and also with SF
4, Br
2, and I
2. All compounds react exothermically, and sometimes explosively, between 80–298 K.[6]
