Fluorosulfuric acid Fluorosulfuric acid Fluorosulfuric acid (IUPAC name: sulfurofluoridic acid) is the inorganic compound with the chemical formula HSOF. It is one of the strongest acids commercially available. The formula HSOF emphasizes its relationship to sulfuric acid, HSO; HSOF is a tetrahedral molecule. It is a colourless liquid, although commercial samples are often yellow. Fluorosulfuric acid is a free-flowing colorless liquid. It is soluble in polar organic solvents (e.g. nitrobenzene, acetic acid, and ethyl acetate), but poorly soluble in nonpolar solvents such as alkanes. Reflecting its strong acidity, it dissolves almost all organic compounds that are even weak proton acceptors. HSOF hydrolyzes
Nitrosylsulfuric acid organic chemistry to prepare diazonium salts from amines. Related NO-delivery reagents include nitrosonium tetrafluoroborate ([NO]BF) and nitrosyl chloride. Nitrosylsulfuric acid is a hazardous material and precautions are indicated. Nitrosylsulfuric acid Nitrosylsulfuric acid is the chemical compound with the formula NOHSO. It is a colourless solid that is used industrially in the production of caprolactam, and was formerly part of the lead chamber process for producing sulfuric acid. The compound is the mixed anhydride of sulfuric acid and nitrous acid. In organic chemistry, it is used as a reagent for nitrosating, as a diazotizing agent, and as an oxidizing agent. A
