Fluoroantimonic acid Chemical Properties,Usage,Production
Chemical Properties
superacid; moisture sensitive [KIR78] [ALD94]
Strongest superacid known
mixture of HF and SbF5 (1:1 is strongest)
Protonate even hydrocarbons to afford carbocations and H2.
2×1019 (20 quintillion) times stronger than 100% sulfuric acid.
Ho values of -31.3
Uses
Hydrogen hexafluoroantimonate(V) is an excellent medium for the preparation of alkylidene oxonium salts.
Preparation
Fluoroantimonic acid is produced by reacting hydrogen fluoride (HF) with antimony pentafluoride (SbF5).
SbF5+HF→SbF6+HF
General Description
HF/SbF5 may be synthesized by mixing hydrogen fluoride and antimony fluoride.1 Fluoroantimonic acid (HF/SbF5), is a combination of SbF5 and HF. It is the known strongest liquid superacid.
