Oxidation diiodine pentoxide

Chlorine dioxide is usually made on-site to bleach flour and wood pulps and for water and waste treatment and is always kept well-diluted to decrease the chances of explosion. Dichlorine heptoxide, CI2O7 or O3CIOCIO3, is a shock-sensitive, oily liquid. It is formally the acid anhydride of perchloric acid. There are no stable bromine oxides at room temperatures. Of the iodine oxides, diiodine pentoxide, I2O5, is the most important. It is used to quantitatively determine carbon monoxide concentrations by the reaction represented in Equation (18.27) ...

There appears to be only one true oxide of iodine, diiodine pentoxide, IjOs- It is a white solid prepared by heating iodic acid(V) to 450 K ... [Pg.337]

Although periodic acid is known (Section 6.6), I2O7 is not. The highest known normal oxide of iodine is diiodine pentoxide, I2O5, which can be made by the dehydration of the white crystals of iodic acid, HIO3, which is itself obtained by the oxidation of iodine with nitric acid. Dehydration is achieved by heating in a stream of dry air ... [Pg.80]
