Iodine pentafluoride is an interhalogen compound consisting of the elements fluorine and iodine in a ratio of 1:5.

Properties

Iodine pentafluoride is a highly reactive, pungent, colorless and fumes in the air liquid violently attacks the respiratory system and reacts with hydrogen-rich organic compounds appearance of flames and formation of hydrofluoric acid. Lewis acids and bases to form the corresponding salts. It has a heat of vaporization of 41.37 kJ / mol, and a heat of fusion of 15.91 kJ / mol. The electrical conductivity is 1.53 × 10 -3S / m.

Iodine pentafluoride is sensitive to hydrolysis and reacts violently with water to iodic acid and hydrogen fluoride:

Production

Iodine pentafluoride can be prepared from the elements, by burning in fluorine iodine.

Use

Iodine pentafluoride is used as the fluorinating reagent in the organic chemistry, and as an etchant in the semiconductor industry.
