詳細

詳細

Fuming sulfuric acid is an inorganic acid, that can be produced by the addition of sulfur trioxide to concentrated sulfuric acid. It is commonly used as a sulfonating reagent in sulfonation reactions. When fuming sulfuric acid is employed as reaction medium, bromination takes place only in the pyridine nucleus of isomeric methylpyridines and 2,6-dimethylpyridine. It can also oxidize fullerene C₆₀ to form fullerene polymers.

アプリケーション

Fuming sulfuric acid may be used as a sulfonating agent for the synthesis of:

• sulfonated poly(1,4-phenylene sulfide)
• water-soluble polyphosphazene polyelectrolyte
• sulfated graphene
