Fluorosulfuric acid can be violent, similar to the addition of water to sulfuric acid but much more violent. 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
11-Aminoundecanoic acid in low moisture absorption compared to polyamide 6 or polyamide 66. In addition, polyamide 11 has very good chemical stability, e.g. against hydrocarbons, low density, good thermal stability, weather resistance and is easy to process. 11-Aminoundecanoic acid 11-Aminoundecanoic acid is an organic compound with the formula HN(CH)COH. This white solid is classified as an amine and a fatty acid. 11-Aminoundecanoic acid is a precursor to Nylon-11. As practiced by Arkema, 11-aminoundecanoic acid is prepared industrially from undecylenic acid, which is derived from castor oil. The synthesis proceeds in four separate reactions: 1.
