superacid; moisture sensitive [KIR78] [ALD94] | [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. | [References]
