Chemical properties

clear colorless to yellowish liquid

The Uses of Heptafluoroisopropyl iodide

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

Non flammable

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.]
