Description

Erzeugung von Alkalijodaten. Durch das Patent 451 656 ist ein Verfahren zur Erzeugung von reinen Alkalijodaten aus Jodiden geschützt. Es besteht darin, daß man Sauerstoff oder diesen abgebende Stoffe auf eine Schmelze von Alkalihvdroxvd und Jedid zweckmäßig im Verhältnis 3 : i einwirken läßt.Generation of alkali iodine data. By patent 451,656 is a method for the production of pure alkali iodates from iodides. It is, that oxygen or substances emitting it on a melt of Alkalihvdroxvd and allows Jedid to work in a ratio of 3: i.

Das Patent 453 127 betrifft die Ausführung dieses Verfahrens bei Temperaturen über 6o0' und Drucken von über ioo Atm.The patent 453 1 27 relates to the execution of this process at temperatures above 6o0 'and printing on ioo atm.

Es wurde nun gefunden, daß die Oxydation von Alkalijodiden zu jodaten auch in Lösungen, z. B. in Wasser, vorgenommen werden kann, wenn man Temperaturen über ioo° und Drucke über i Atm. anwendet. Besser und schneller verläuft die Reaktion in Gegenwart von Katalysatoren, z. B. von Hydroxylionen.It has now been found that the oxidation of alkali iodides to iodate also in solutions, e.g. B. in water, can be done if you have temperatures over ioo ° and pressures over i Atm. applies. The reaction is better and faster in the presence of catalysts, e.g. B. of hydroxyl ions.
