حمض الفلوروسلفونيك
– الحمض الفائق هو حمض له درجة حموضة أكثر من حمض الكبريتيك النقي. بعض هذه الأحماض قادر على إنتاج أي شيء تقريبا ، بما في ذلك الهيدروكربونات. مثال على الأحماض الفائقة هو <anchor>حمض الفلوروسلفونيك</anchor> HSO3F.

Chemical compound

**Fluorosulfuric acid** ( [IUPAC](/wiki/International_Union_of_Pure_and_Applied_Chemistry "International Union of Pure and Applied Chemistry") name: **sulfurofluoridic acid**) is the [inorganic compound](/wiki/Inorganic_compound "Inorganic compound") with the [chemical formula](/wiki/Chemical_formula "Chemical formula") HSO3F. It is one of the strongest acids commercially available. It is a tetrahedral molecule and is closely related to [sulfuric acid](/wiki/Sulfuric_acid "Sulfuric acid"), H2SO4, substituting a fluorine atom for one of the hydroxyl groups. It is a colourless liquid, although commercial samples are often yellow.[\[2\]](#cite_note-Ullmann-2)

## Properties

\[ [edit](/w/index.php?title=Fluorosulfuric_acid&action=edit&section=1 "Edit section: Properties")\]

Fluorosulfuric acid is a free-flowing colorless liquid. It is soluble in polar organic solvents (e.g. [nitrobenzene](/wiki/Nitrobenzene "Nitrobenzene"), [acetic acid](/wiki/Acetic_acid "Acetic acid"), and [ethyl acetate](/wiki/Ethyl_acetate "Ethyl acetate")), but poorly soluble in nonpolar solvents such as alkanes.

HSO3F is one of the strongest known simple [Brønsted acids](/wiki/Br%C3%B8nsted_acid "Brønsted acid").[\[3\]](#cite_note-3) It has an _H_ 0 value of −15.1 compared to −12 for sulfuric acid. The combination of HSO3F and the [Lewis acid](/wiki/Lewis_acid "Lewis acid") [antimony pentafluoride](/wiki/Antimony_pentafluoride "Antimony pentafluoride") produces " [Magic acid](/wiki/Magic_acid "Magic acid")", which is a far stronger protonating agent. These acids are categorized as " [superacids](/wiki/Superacids "Superacids")", acids stronger than 100% sulfuric acid.

Reflecting its strong acidity, HSO3F dissolves almost all organic compounds that are even weak proton acceptors.[\[4\]](#cite_note-4) HSO3F [hydrolyzes](/wiki/Hydrolysis "Hydrolysis") slowly to [hydrogen fluoride](/wiki/Hydrogen_fluoride "Hydrogen fluoride") (HF) and [sulfuric acid](/wiki/Sulfuric_acid "Sulfuric acid"). The related [triflic acid](/wiki/Triflic_acid "Triflic acid") (CF3SO3H) retains the high acidity of HSO3F but is more hydrolytically stable. The self-ionization of fluorosulfonic acid also occurs:

2 HSO3F ⇌ \[H2SO3F\]+ \+ \[SO3F\]− _K_ = 4.0 × 10−8 (at 298 K)

HSO3F isomerizes [alkanes](/wiki/Alkanes "Alkanes") and catalyzes the alkylation of hydrocarbons with alkenes,[\[5\]](#cite_note-5) although it is unclear if such applications are of commercial importance. It can also be used as a laboratory fluorinating agent.[\[6\]](#cite_note-ref3-6)

## Production

\[ [edit](/w/index.php?title=Fluorosulfuric_acid&action=edit&section=2 "Edit section: Production")\]

Fluorosulfuric acid is prepared by the reaction of HF and [sulfur trioxide](/wiki/Sulfur_trioxide "Sulfur trioxide"):[\[2\]](#cite_note-Ullmann-2)

SO3 \+ HF → HSO3F

Alternatively, [KHF2](/wiki/Potassium_bifluoride "Potassium bifluoride") or [CaF2](/wiki/Calcium_fluoride "Calcium fluoride") can be treated with [oleum](/wiki/Oleum "Oleum") at 250 °C. Once freed from HF by sweeping with an inert gas, HSO3F can be distilled in a glass apparatus.[\[6\]](#cite_note-ref3-6)

## Safety

\[ [edit](/w/index.php?title=Fluorosulfuric_acid&action=edit&section=3 "Edit section: Safety")\]

Fluorosulfuric acid is considered to be highly toxic and extremely corrosive. It hydrolyzes to release HF. Addition of water to HSO3F can be violent, similar to the addition of water to sulfuric acid but much more violent.
