Description

Verfahren zur Gewinnung von Jodverbindungen bzw. von Jod. Es ist bekannt, daß Kohle pflanzlichen oder tierischen Ursprungs ein gutes Adsorptionsvermögen für Jod besitzt. Mit gesteigerter Aktivität wächst ihre Adsorptionskraft, mit Hilfe deren man Jod, das z. B. aus jodhaltigen Flüssigkeiten in Freiheit gesetzt wird, an die Kohle binden kann. Man hat aber bisher Schwierigkeiten gehabt, aus solcher jodlialtigen Kohle das Jod in praktischer und ökonomischer Weise wiederzugewinnen.Process for the production of iodine compounds or of iodine. It is known, that coal of vegetable or animal origin has a good adsorption capacity for Possesses iodine. With increased activity, their adsorptive power grows, with help whose one iodine, the z. B. is released from iodine-containing liquids, can bind to the coal. But so far one has had difficulties from such iodized coal to recover the iodine in a practical and economical way.

Es wurde nun gefunden, daß man dieses Ziel in der Weise erreichen kann, daß man die jodhaltige Kohle mit Wasser unter Zusatz von geeigneten Metallen bei gewöhnlicher oder erhöhter Temperatur. behandelt. Hierbei geht das Jod als Metalljodverbindung in Lösung, die dann nach bekannten Methoden weiterverarbeitet wird.It has now been found that this goal can be achieved in this way can that you the iodine-containing coal with water with the addition of suitable metals at ordinary or elevated temperature. treated. Here the iodine goes as a metal iodine compound in solution, which is then processed further using known methods.

Der Erfolg des Verfahrens ist überraschend, da das an die Kohle gebundene Jod nicht durch Wasser herausgelöst wird und somit eigentlich die Voraussetzung für eine Reaktion zwischen Jod und Metall fehlt.The success of the process is surprising since it is bound to the coal Iodine is not dissolved out by water and is therefore actually the prerequisite for a reaction between iodine and metal is absent.

B e i s p i e 1. to Gewichtsteile hochaktive Kohle, die @z. B. aus einer jodhaltigen Flüssigkeit r Gewichtsteil Jod absorbiert haben, werden mit z Gewichtsteil Eisenfeile in r5o Gewichtsteilen Wasser etwa eine Stunde lang erwärmt. Hierauf filtriert rcnan die entstandene Eisenjodürlösung ab, wäscht die Kohle gut aus und verarbeitet :dann die gesammelten Filtrate in bekannter Weise weiter entweder auf Jodrverbindungen oder auf Jod. Die Ausbeute an Jod beträgt etwa 95 Prozent der Theorie.B e i s p i e 1. to parts by weight of highly active carbon, the @z. B. off an iodine-containing liquid have absorbed r part by weight of iodine, with z Part by weight of iron file heated in 50 parts by weight of water for about an hour. The iron iodine solution formed is then filtered off and the charcoal washes well from and processed: then the collected filtrates either continue in a known manner on iodine compounds or on iodine. The yield of iodine is about 95 percent of the Theory.

In analoger Weise verfährt man bei Anwendung anderer geeigneter Metalle, wie z. B. Zink, Aluminium, Kupfer usw.The same procedure is followed when using other suitable metals, such as B. zinc, aluminum, copper, etc.
