Heptafluoro-propane

The electrochemical perfluorination of propane-2-thiol46 gives pcntafluoro(heptafluoro-propan-2-yl)-/.6-sulfane (yield 1.7%), fragmented fluorocarbons (main product octafluoro-propane, 48.6%) and sulfur hexafluoride (38.9%) (electrolyte anhyd HF effective surface area of nickel anodes 770 cm2 voltage 4.7-6.1 V current density 2.6 A dm 2 temperature 8 10 C). [Pg.315]

The reaction has been extended to the preparation of the perfluoro-propyliodophosphines by reaction of 1-iodo-l, 1,2,2,3,3,3-heptafluoro-propane with red phosphorus (16). [Pg.9]

This would have results in 77 hits from l,2-[propadiene, 1,1,2,2-tetrafluoro-] with a boiling point of —38 °C, to [propane, l,l,l,2,3,3,3-heptafluoro-2-(trifluoromethyl)-] with a boiling point of 0 °C. Out of 77 hits, 49 of them contain elements that include B, Si, N, P, As, O, S, Cl, Br, and I, and perhaps too toxic to be considered as refrigerants seriously. There are 11 hits that are hydrocarbons, such as butane, which would be too flammable to be considered. Perhaps we would eliminate the six hits that have double or triple bonds, as they tend to be less stable and could polymerize. The remaining ones are all hydrofluorocarbons (HECs) without chlorine, and the prime candidates are C2H2E4, C3H3E5, and C4F10. [Pg.65]

Bromofluoroalkanes can be converted into the 2-bromo isomers with ACF and HFP, but only with low conversion. In contrast, heptafluoro-l-iodo-propane (17) transforms quantitatively into the 2-iodo isomer 18.28... [Pg.166]
