Description

Herstellung von Alkalijodaten. Läßt man auf Alkalijoclide Sauerstoff einwirken, so erhält man kein jodat, da die Reaktionsgeschwindigkeit zu gering ist.Production of alkali iodine data. Oxygen is left on the alkali metal halide act, no iodate is obtained because the reaction speed is too slow.

Es wurde gefunden, daß diese dadurch sehr erhöht wird, daß man die jodide in schmelzendes Alkali einträgt. Z. B. erhält man durch Einwirkung von Sauerstoff oder Sauerstoff abgebende Stoffe bei etwa ¢0o° auf eine Schmelze von KOH und Kj (Verhältnis zweckmäßig 3: i) Kaliumjodat. Noch: günstiger gestaltet sich das Ergebnis bei Einwirkung von Sauerstoff oder diesen abgebende Stoffe bei etwa 5oo° bei einem Druck von vorteilhaft 5 bis i 5 Atm. Man kann so das Kaliumjodid quantitativ in Kaliumjodat überfühTen.It has been found that this is greatly increased by the fact that the iodide enters into melting alkali. For example, exposure to oxygen gives or oxygen-releasing substances at about ¢ 0o ° on a melt of KOH and Kj (Appropriate ratio 3: i) Potassium iodate. Even more: the result is more favorable when exposed to oxygen or substances emitting it at about 5oo ° at a Pressure of advantageously 5 to 15 atm. The potassium iodide can be quantitatively converted into Overfeed potassium iodate.
