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
Dihydroxymalonic acid heated with urea to 100 °C, it forms allantoin. By continued boiling of its aqueous solution it is decomposed into carbon dioxide and glyoxylic acid. Dihydroxymalonic acid Dihydroxymalonic acid is an organic compound with formula CHO or HO-(C=O)-C(OH)-(C=O)-OH, found in some plants such as alfalfa and in beet molasses. The compound may also be called dihydroxymesoxalic acid, dihydroxypropanedioic acid. It can be viewed as a hydrate derivative of mesoxalic acid, and indeed it is often called mesoxalic acid monohydrate and other silmilar names. This compound is unusual in containing stable geminal hydroxy groups. Dihydroxymalonic acid is a water-soluble white solid.
