Description
Herstellung von Ferri-y-hydroxyd Bekanntlich kommen die Hydroxyde des dreiwertigen Eisens in verschiedenen Formen vor, die sich nicht nur durch Gehalt an Hydratwasser unterscheiden, sondern offenbar auch durch die Elektronenkonfiguration des Eisens selbst; denn die sogenannte y-Konfiguration unterscheidet sich im Röntgenspektrum deutlich von der a-Konfiguration. Die erstere geht beim Entwässern bei etwa 2oo° C in eine besonders lockere Form des y-Oxyds über, das ferromagnetische Eigenschaften besitzt und die Fähigkeit hat, biologisch im Sinne der Katalase zu wirken.Manufacture of ferric y-hydroxide It is well known that the hydroxides come of trivalent iron in various forms, which differ not only by content differ in terms of water of hydration, but apparently also through the electron configuration of iron itself; because the so-called y-configuration differs in the X-ray spectrum clearly from the a configuration. The former goes at about 200 ° when draining C in a particularly loose form of the y-oxide, which has ferromagnetic properties and has the ability to act biologically in the sense of catalase.
Es wurde gefunden, daß man das Ferri-y-hydroxyd dadurch gewinnen kann, daß man Lösungen von möglichst reinem Ferrochlorid bei Gegenwart von Luft oder Sauerstoff mit Pyridin, Piperidin, Anilin oder anderen organischen Basen ausfällt. Eisenchloridlösungen, die einen für die Gewinnung des y-Hydrats hinreichenden Reinheitsgrad besitzen, erhält man z. B. durch Auflösen von aus Eisenpentacarbonyl gewonnenem Eisen in Salzsäure. Interessanterweise ergibt das mit anderen Säuren, z. B. Schwefelsäure, aufgelöste Eisen keine reine y-Form, sondern ein Gemisch mit der a-Form. Beispiel 5o g reinstes Eisenpulver werden mit 25o ccm arsenfreier Salzsäure vom spezifischen Gewicht 1,2, bis 1,3 übergossen. Wenn ,die überstehende Lösung gegen Congopapier neutral reagiert, wird durch ein gehärtetes Filter vom überschüssigen Eisen filtriert.It has been found that ferric y-hydroxide can be obtained by precipitating solutions of the purest possible ferrous chloride in the presence of air or oxygen with pyridine, piperidine, aniline or other organic bases. Iron chloride solutions that have a sufficient degree of purity for the recovery of the y-hydrate are obtained, for. B. by dissolving iron obtained from iron pentacarbonyl in hydrochloric acid. Interestingly, with other acids, e.g. B. sulfuric acid, dissolved iron is not a pure y-form, but a mixture with the a-form. Example 50 g of the purest iron powder are doused with 250 cc of arsenic-free hydrochloric acid with a specific gravity of 1.2 to 1.3 . If the supernatant solution reacts neutrally to Congo paper, the excess iron is filtered through a hardened filter.
zoo ccm dieser Ferrochlorid-Lösung werden mit 2 ccm Pyridin versetzt und durch die Lösung bei einer Temperatur von 6o° C 2 bis 3 Stunden Luft durchgeleitet. Der ausgeschiedene Niederschlag wird filtriert und bis zum Verschwinden der Chlorreaktion gewaschen. Das Filtrat wird nochmals mit 2 ccm Pyridin versetzt, und wiederum wird 2 Stunden lang Luft durchgeleitet; der sich abscheidende Niederschlag wird abfiltriert und gewaschen.zoo cc of this ferrous chloride solution are mixed with 2 cc of pyridine and air is passed through the solution at a temperature of 60 ° C. for 2 to 3 hours. The deposited precipitate is filtered and until the chlorine reaction disappears washed. The filtrate is mixed again with 2 cc of pyridine, and again is Air passed through for 2 hours; the precipitate which separates out is filtered off and washed.
