화학적 성질
iodine pentafluoride (IF5) is a colorless to pale yellow fuming liquid with a pungent odor. The highly reactive IF5 (melting point 9.4 °C) is distillable at 100.5 °C without any decomposition. Decomposition commences at temperatures above 400 °C. IF5 is not as popular as p-TolIF2 because F2 gas is used in its preparation and it decomposes in air by moisture emitting corrosive HF.Iodine pentafluoride has good thermal stability and is the most stable halogen compound. The reactivity of IF5 is much weaker than that of other halogen compounds, and it does not interact with silicon, magnesium, copper, iron, and chromium at room temperature, and only interacts with molybdenum, tungsten, phosphorus, arsenic, antimony, boron, etc. The corresponding fluorides are generated, such as:2 IF5 + 2 Sb → 2 SbF5 + I26 IF5 + 10 B → 10 BF3 + 15 I2It is the least reactive of the halogen fluorides and classified as a soft fluorinating reagent. It is used as a mildest, selective fluorinating reagent in the fluorination of organic molecules.

Reactivity Profile
A powerful oxidizer. Attack glass. Reacts violently with water or strong bases (potassium hydroxide, sodium hydroxide). It chars and usually ignites organic matter. Contact with boron, silicon, red phosphorus, sulfur, arsenic, antimony, bismuth, molybdenum and tungsten causes incandescence. Contact with potassium or sodium leads to explosions. Causes aluminum (foil, powder) to ignite. Explosive reactions with tetraiodoethylene, diethylaminotrimethylsilane. Violent reactions with benzene, dimethyl sulfoxide, tetraiodoethylene [Bretherick, 5th ed., 1995, p. 1434]. IF5 reacts explosively with diethylaminotrimethylsilane even at low temperature.

응용 분야
용도Iodine 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.
일반 설명Iodine 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.
제조 방법
Iodine 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.
