Synthesis and reactions
(CF3)2CO is prepared in a two step process from perfluoropropene. In the first step KF catalyzes the reaction of the alkene with elemental sulfur to give the 1,3-dithete [(CF3)2CS]2. This species is then oxidized by iodate to give (CF3)2CO. [1]
Uses
Hexafluoroacetone is mostly employed in organic synthesis, but it is also the main chemical intermediate used in the production of hexafluoroisopropanol, as well as polymethyl methacrylates and polyesters for textile coating. Organic synthesis is a special branch of Chemical synthesis and is concerned with the construction of Organic compounds via Organic reactions Organic Hexafluoroisopropanol, commonly abbreviated HFIP is the Organic compound with the formula (CF32CHOH Poly(methyl methacrylate ( PMMA) or poly(methyl 2-methylpropenoate is a Thermoplastic and transparent Plastic. Polyester is a category of Polymers which contain the Ester Functional group in their main chain Hexafluoroacetone can be employed as a solvent for acetal resins, polyamides and polyglycolide or as a polymer adhesive. A polyamide is a Polymer containing Monomers of Amides joined by Peptide bonds They can occur both naturally examples being Proteins Polyglycolide or Polyglycolic acid ( PGA) is a Biodegradable, Thermoplastic Polymer and the simplest linear Aliphatic A polymer is a large Molecule ( Macromolecule) composed of repeating Structural units typically connected by Covalent Chemical bonds
Reactivity
Hexafluoroacetone is a reactive substance, acting primarily as an electrophile. In Chemistry, an electrophile (literally electron-lover) is a Reagent attracted to Electrons that participates in a chemical reaction by accepting It will react vigorously with water, irreversibly forming a hydrate. Such hydrates are acidic that react with most metals to generate hydrogen. Hydrogen (ˈhaɪdrədʒən is the Chemical element with Atomic number 1 Hexafluoroacetone violently reacts in the presence of alkali. Related to its tendency to hydrate, (CF3)2CO adds ammonia to give (CF3)2C(OH)(NH2) which can be dehydrated with POCl3 to give (CF3)2CNH. Ammonia is a compound with the formula N[[hydrogen H3]] It is normally encountered as a Gas with a characteristic pungent Odor [2]
