Pentafluoroethyl iodide explained

Pentafluoroethyl iodide is a suggested component of a fire-extinguishing composition.^[1] It is a very dense gas.

Production

Pentafluoroethyl iodide can be produced by electrochemical fluorination of 1,1,2,2-tetrafluoro-1,2-diiodoethane.^[2]

2 C2F4I2 + 2 HF -> C2F5I + I2 + H2

It can also be produced by react tetrafluoroethylene, iodine and iodine pentafluoride.^[3]

5 C2F4 + 2 I2 + IF5 -> 5 C2F5I

Properties

Pentafluoroethyl iodide is a pungent colourless gas and an anesthetic.^{[4] [5]}

Uses

Pentafluoroethyl iodide is an intermediate of preparing other compounds.^{[6] [7] [8]}
