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
Vinylphosphonic acid known for promoting adhesion between organic and inorganic phases. Such interfaces exist between coatings and the substrates to which they are applied. Both vinylphosphonic acid homopolymer and its copolymers are the basis of many products which have found applications in scale and corrosion treatment. Polyvinylphosphonic acid is an essential component for the polymer electrolyte membranes used in fuel cell development, in the medical field as dental cements, hydrogels for drug delivery, and components in biomimetic mineralization. Vinylphosphonic acid Vinylphosphonic acid is an organophosphorus compound with the formula CHPOH. It is a colorless, low-melting solid although commercial samples are often yellowish
