Overview
Iodine pentafluoride appears as a toxic colorless fuming liquid (m.p. 9 °C). Decomposed by water to iodine and hydrofluoric acid. Contact with organic materials may cause their ignition. Corrosive to metals and tissue. Prolonged exposure of the container to fire or heat may result in their violent rupturing and rocketing. Prolonged exposure to low concentrations or short term exposure to high concentrations may result in adverse health effects.

Applications
UsesIodine pentafluoride is a fluorinating agent and strong oxidant, which plays an important role in organic synthesis. It can be used to prepare pentafluoroiodoethane:5 CF2=CF2 + IF5 + 2 I2 → 5 C2F5IIn addition, iodine pentafluoride can also react with isothiocyanato to generate fluorinated hydrocarbon derivatives, and to synthesize other fluorine-containing compounds.Iodine pentafluoride (IF5) is rarely used to fluoride common organic compounds due to the difficulty in controlling their reactivity.
General DescriptionIodine pentafluoride appears as a toxic colorless fuming liquid (m.p. 9° C). Decomposed by water to iodine and hydrofluoric acid. Contact with organic materials may cause their ignition. Corrosive to metals and tissue. Prolonged exposure of the container to fire or heat may result in their violent rupturing and rocketing. Prolonged exposure to low concentrations or short term exposure to high concentrations may result in adverse health effects.
Preparation methods
PreparationIodine pentafluoride(IF5) is produced by the action of elemental fluorine on iodine which has a low melting point. The reaction is performed either in solvent or heating iodine to maintain its liquid state. In a commercial preparation about one percent iodine is dissolved in IF5 and brought into fluorination chamber where iodine reacts with fluorine and produces more IF5 which is returned to the receiving vessel. Only a small portion of IF5 is withdrawn from the receiving vessel as product, while the major portion of IF5 is used for dissolving more iodine. This process goes on and on until all iodine is converted into IF5.In another industrial process, iodine is heated above its melting point (113℃) and reacted with elemental fluorine under three atmosphere of pressure. A precaution is taken not to heat iodine above 150℃ to avoid the formation of another product, IF7. Fluorine is added continuously until all iodine has reacted and converted to IF5.
