HEXAFLUOROACETONE Chemical Properties
Hexafluoroacetone(684-16-2) is a chemical compound with the formula CF3-CO-CF3. It is structurally similar to acetone, however its reactivity is markedly different. It comes in the form of a colourless, hygroscopic, nonflammable, highly reactive gas characterized by a musty odour. The most common form of this substance is hexafluoroacetone sesquihydrate (1.5 H2O), which is a gem-diol.

HEXAFLUOROACETONE Uses
Hexafluoroacetone(684-16-2) 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. Hexafluoroacetone(684-16-2) can be employed as a solvent for acetal resins, polyamides and polyglycolide or as a polymer adhesive.
HEXAFLUOROACETONE Production
Hexafluoroacetone(684-16-2) 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.
