Perfluoroacetone hydrate - Reference Information
| overview | hexafluoroacetone is also called perfluoroacetone, 1,1,3,3, 3-hexafluoro-2-acetone. In 1941, Fukuhara, etc. were produced by direct fluorination of acetone. Non-combustible gas. Relative molecular mass 166.02. Melting point -125.45 ℃. Boiling point -27.28 ℃. The critical pressure is 2.834MPa. Good thermal stability, no decomposition below 300 ℃. It is divided into hexafluoroethane and carbon monoxide at 550 ℃, and trifluoroacetyl fluoride (F3CCOF) and 2-difluoromethylene hexafluoropropane are generated at 600 ℃. Due to the strong electron-withdrawing nature of the CF3 group, the carbonyl group containing CF3 is vulnerable to the attack of nucleophiles, which is the characteristic of the reactivity of hexafluoroacetone. Hexafluoroacetone easily reacts with water to form acidic gemediol (CF3)2(OH)2. Reacts with fatty alcohols to produce hemiketal. Reacts with hydrogen fluoride to produce perfluoropropanol. Reacts with metal fluorides to produce stable (CF3)2CFO-anions. Hexafluoroacetone cannot be homopolymerized, but it can be copolymerized with olefins and alkylene oxide. Using this feature, high temperature resistant and corrosion resistant coatings and adhesives can be prepared. Hexafluoroacetone trihydrate is a hydrate of hexafluoroacetone. |
| use | hexafluoroacetone trihydrate can be used to produce inhalation anesthetic sevoflurane and high-end vulcanizing agent bisphenol AF of fluoroelastomer; And used to prepare high-performance fluorine-containing products such as fluorine-containing polyimide |
