Description

Verfahren zur Herstellung von beständigen Lösungen des Ferroeisens Es ist für die therapeutische Verwendung von Lösungen,' welche das Eisen in der zweiwertigen Form enthalten, eine bekannte Schwierigkeit, zu verhindern, daß in der Lösung die zweiwertige Form des Eisens in die physiologisch nahezu unwirksame dreiwertige Form übergeht. Schon die Erhaltung der zweiwertigen Form des Eisens in festen Zubereitungen, welche Ferrosalze enthalten, machte die Zumischung reduzierend wirkender Stoffe, z. B. von Glycogelatine oder von Zucker, notwendig.Process for the production of permanent solutions of ferrous iron It is for the therapeutic use of solutions, 'which contain the iron in the divalent form, a known difficulty in preventing in the solution converts the divalent form of iron into the physiologically almost ineffective one trivalent form passes over. Just the preservation of the bivalent form of iron In solid preparations, which contain ferrous salts, the admixture made reducing acting substances, e.g. B. of glycogelatine or sugar, necessary.

Es ist weiter bekannt, daß das Ferrisaccharat durch reduzierende Zucker beim Erwärmen zu Ferroverbindungen reduziert wird und daß derartige Lösungen von Ferrosaccharaten durch Zusatz von Alkali für flüssige ferrosalzhaltige Präparate verwendet werden können. Hierbei handelt es sich jedoch um eine komplexe, salzartige Verbindung zwischen Eisenhydroxyd und Zucker, die keine Ionenreaktionen von zwei- oder dreiwertigem Eisen mehr geben, wodurch die auf dem zweiwertigen Eisen in beruhende physiologische Wirkung des Eisens zum mindesten teilweise in Frage gestellt ist. It is also known that the ferris saccharate by reducing Sugar is reduced to ferrous compounds when heated and that such solutions of ferrous saccharates by adding alkali for liquid preparations containing ferrous salts can be used. However, this is a complex, salty one Connection between iron hydroxide and sugar, which does not have any ionic reactions of two or give more trivalent iron, whereby the ones based on the bivalent iron in The physiological effect of iron is at least partially questioned.

Ferner ist es bekannt, Lösungen von Ferrosalzen dadurch zu stabilisieren, daß man diesen Lösungen stark ungesättigte Verbindungen hinzufügt, die eine ungesättigte Dienolgruppe enthalten. Aber einmal sind derartige Verbindungen keine technisch leicht zugänglichen Produkte und zum anderen stellen sie Verbindungen dar, die, wie z. B. die Ascorbinsäure, selbst leicht oxydiert werden und dadurch in mehr oder weniger kurzer Zeit die Fähigkeit verlieren, die Oxydation des Ferroeisens zu verhindern. It is also known to stabilize solutions of ferrous salts by that one adds strongly unsaturated compounds to these solutions, the one unsaturated Contain dienol group. But for one thing, such connections are not technical easily accessible products and, on the other hand, they represent connections that, such as B. the ascorbic acid, are itself easily oxidized and thereby in more or lose the ability to prevent the oxidation of ferrous iron in a less short period of time.

Es wurde gefunden, daß man zu äußerst beständigen Lösungen des Ferroeisens gelangt, wenn man metallisches Eisen in gepulverter Form mit Lösungen von Polyoxycarbonylverbindungen, wie z. B. Lösungen der technisch leicht zugänglichen Glucose, in der Hitze unter Druck behandelt. It has been found that extremely stable solutions of ferrous iron can be obtained when metallic iron in powdered form is mixed with solutions of polyoxycarbonyl compounds, such as B. Solutions of technically easily accessible glucose, in the heat under Pressure treated.

Die auf diese Weise hergestellten Eisenlösungen liefern vollständige Eisenion-Reaktionen, und zwar ausnahmslos die Reaktionen des zweiwertigen Eisens. The iron solutions prepared in this way provide complete Iron ion reactions, and without exception the reactions of divalent iron.

Da die Lösungen das Ferroeisen in praktisch unbegrenzt haltbarer, ionisierter Form enthalten, können sie für wirkungsvolle, arzneiliche Zubereitungen verwendet werden. Since the solutions keep ferrous iron in a practically indefinitely durable, contain ionized form, they can be used for effective medicinal preparations be used.

Beispiel I 6 Teile Ferrum reductum werden mit einer Lösung von 50 Teilen Glucose in 200 Teilen Wasser in einem Autoklaven allmählich auf I400 erhitzt und 8 Stunden bei dieser Temperatur gehalten. Nach dem Abkühlen wird die erhaltene schwarzbraune Lösung filtriert und mit Wasser auf 220 Teile aufgefüllt. Die so erhaltene Lösung mit etwa I°lo Eisen enthält das Metall beständig in der Ferroforin. Example I 6 parts of Ferrum reductum are mixed with a solution of 50 Parts of glucose in 200 parts of water are gradually heated to 1400 in an autoclave and held at this temperature for 8 hours. After cooling, the obtained Filtered black-brown solution and made up to 220 parts with water. The thus obtained A solution with about 1 ° lo iron contains the metal permanently in the ferroforin.

Beispiel 2 5 Teile Eisenpulver werden mit einer Lösung von 50 Teilen 2, 3, 4, s-Tetroxyvaleraldehyd in 150 Teilen Wasser unter Druck IO Stunden lang auf 140 bis I600 erhitzt. Die erkaltete Lösung wird filtriert und auf ein Volumen von 200 Teilen gebracht. Example 2 5 parts of iron powder are mixed with a solution of 50 parts 2, 3, 4, s-tetroxyvaleraldehyde in 150 parts of water under pressure for 10 hours heated to 140 to 1600. The cooled solution is filtered and made up to volume of 200 parts brought.

Die Lösung enthält I,6 Teile Eisen.The solution contains 1.6 parts of iron.
