Description
Reinigung von eisenhaltigen Aluminiumsalzlaugen Gegenstand der Erfindung ist ein Verfahren zur Reinigung von eisenhaltigen Aluminiumsalzlösungen, welches darauf beruht, daß gewissen organischen Lösungsmitteln die Fähigkeit zukommt, das Eisen als Ferrichlorid aufzunehmen, so daß bei deren Vermischung mit der Salzlösung eine praktisch eisenfreie Aluminiumsalzlauge entsteht. Weitere Voraussetzung für die Brauchbarkeit dieser organischen Lösungsmittel ist, daß sie in Wasser wenig oder gar nicht löslich sind und wenig flüchtig sind, vorteilhaft einen Siedepunkt oberhalb zoo° aufweisen. Zu diesen Lösungsmitteln gehören beispielsweise Cyclohexanon, Methylcyclohexanon, Benzylalkohol, Isoamylalkohol, Isobutylacetat und andere.Purification of iron-containing aluminum brine is the subject of the invention is a process for the purification of iron-containing aluminum salt solutions, which is based on the fact that certain organic solvents have the ability to To include iron as ferric chloride, so that when it is mixed with the salt solution a practically iron-free aluminum brine is produced. Another requirement for The usefulness of these organic solvents is that they do little in water or are not soluble at all and are not very volatile, advantageously have a boiling point show above zoo °. These solvents include, for example, cyclohexanone, Methylcyclohexanone, benzyl alcohol, isoamyl alcohol, isobutyl acetate, and others.
Beispiel i 1 einer Aluminiumchloridlauge entsprechend etwa 9o g A1203 und etwa Z g Fe" 03 im Liter wird bis auf 65o bis 700 g eingedampft und nach dem Erkalten mit dreimal je Zoo ccm Methylcyclohexanon ausgeschüttelt.Example 11 of an aluminum chloride liquor corresponding to about 90 g A1203 and about Z g Fe "03 per liter is evaporated down to 65o to 700 g and, after cooling, extracted three times per zoo ccm of methylcyclohexanone.
Die extrahierte Lösung enthält auf roo Teile Al. 0, nur mehr o,025 Teile Fe, 0, Das abgetrennte eisenchloridhaltige Methylcyclohexanon läßt sich durch einfaches Ausschütteln mit Wasser wieder vom Eisen befreien und in das Verfahren zurückführen.The extracted solution contains parts of Al. 0, only 0.025 parts Fe, 0, The separated iron chloride-containing methylcyclohexanone can be freed from iron by simply shaking with water and returned to the process.
Das Arbeiten mit den genannten Lösungsmitteln bietet praktisch gegenüber demjenigen mit Äther, der schon als Lösungsmittel für Eisenchlorid vorgeschlagen worden ist, den Vorteil, daß wegen der höheren Siedepunkte der vorgeschlagenen Mittel und wegen ihrer niedrigen Löslichkeit in Wasser geringere Verluste an denselben eintreten, sowie den weiteren Vorteil, daß die Lösungsmittel, wie oben erwähnt, unmittelbar nach dem Ausschütteln mit Wasser wieder verwendungsfähig sind.Working with the solvents mentioned offers practically opposite the one with ether who has already been suggested as a solvent for ferric chloride has the advantage that because of the higher boiling points of the proposed agents and because of their low solubility in water, lower losses of the same occur, as well as the further advantage that the solvents, as mentioned above, can be used again immediately after shaking with water.
