| Heptafluoroisopropyl iodide Usage And Synthesis |
| Chemical Properties | clear colorless to yellowish liquid | | Uses | Heptafluoro-2-iodopropane may be used in the preparation of perfluoropropyl magnesium bromide and perfluoropropyl magnesium iodide. It may be used as chain-transfer agent in telomerization reactions of:- 1,1-difluoroethylene and tetrafluoroethylene
- CF3I, C2F5I and n-C3F7I with 1,1-difluoroethylene
- n-C3F7I with tetrafluoroethylene
| | General Description | Heptafluoro-2-iodopropane is a secondary fluoro alkyl iodide. It can be prepared by addition of iodine monofluoride to hexafluoropropene. | | Flammability and Explosibility | Nonflammable | | Purification Methods | Purify it by gas chromatography on a triacetin (glyceryl triacetate) column, followed by bulb-to-bulb distillation at low temperature. Store it over Cu powder to stabilise it. UV has max at 271nm ( 240) in pet ether (b 60-80o). [Haszeldine J Chem Soc 1767, 3761 1953, Beilstein 1 III 255, 1 IV 225.] |
