MAGIC ACID Chemical Properties,Usage,Production

Uses

Magic acid is a strong conjugate Br?nsted-Lewis superacid system widely used for the generation of stable carbocations  and as catalyst and reagent for alkylation, isomerization, rearrangement, cyclization, oxyfunctionalization,  formylation, sulfonation, and fluorosulfonation.

Preparation

HSO3F-SbF5 is prepared by mixing Fluorosulfuric Acid and Antimony(V) Fluoride at  rt under dry nitrogen or argon atmosphere. The commercially available Magic Acid is a 50:50 mol % mixture  of the two components. Magic Acid diluted in fluorosulfuric acid to various extents is also available.  Commercial Magic Acid generally contains some HF in the form of conjugate acid.

storage

Magic Acid is highly toxic, moisture sensitive, and corrosive, and  should always be handled in a fume hood with proper protection. Glass is attacked by Magic Acid very  slowly when moisture is excluded. Therefore, glassware may be used for handling and carrying out reactions  involving Magic Acid. Teflon containers are recommended for long-term laboratory storage of Magic Acid.
