Description

Verfahren zur Herstellung von Präparaten zur Erzeugung von Aluminiumformiatlösungen. Man hat vorgeschlagen, ameisensaure Tonerde durch Einwirkung ameisensauren Natriums auf Aluminiumsulfat herzustellen, und zwar so, daß man das bei der Reaktion sich bildende Natriumsulfat abtrennt. Diese Darstellung, die von konzentrierten Lösungen ausgehen muß, ist umständlich, erfordert Innehaltung bestimmter niedriger Temperatur und besondere Apparaturen.Process for the production of preparations for the production of aluminum formate solutions. It has been proposed to form alumina by the action of sodium formate on aluminum sulphate, in such a way that it becomes apparent during the reaction separating forming sodium sulfate. This representation that of concentrated solutions Going out is cumbersome and requires a certain low temperature to be maintained and special equipment.

Es hat sich nun herausgestellt, daß diese Mißstände vermieden werden können, wenn man ameisensaures Natrium und Aluminiumsalze in solcher Verdünnung aufeinander einwirken läßt, daß weder die Komponenten noch die Umsetzungsprodukte sich ausscheiden können. Die Anwesenheit von Natriumsulfat ist in verschiedener, besonders pharmakologischer Hinsicht bei einem .derartigen Verfahren von Bedeutung. Es gelingt bei dem Arbeiten in der angedeuteten Weise sogar, den schwerlöslichen Alaun für .die Reaktion nutzbringend zu verwerten.It has now been found that these abuses can be avoided can, if one has sodium formate and aluminum salts in such dilution can interact that neither the components nor the reaction products can retire. The presence of sodium sulfate is in various, particularly pharmacologically important in such a process. When working in the manner indicated, it even succeeds in those that are difficult to dissolve To utilize alum for .the reaction beneficially.

Soll die Herstellung der Lösungen nicht der Fabrikation, sondern dem Verbraucher überlassen werden, um dadurch an Flaschen, Verpackungsmaterial, Transportkosten für die mitzuschleppende Flüssigkeit zu sparen, so kann man nach der Erfindung dem Verbraucher ein festes Präparat in -die Hand geben.Should the production of the solutions not be the production, but the Consumers are left to pay for bottles, packaging material, transport costs to save for the entrained liquid, so you can according to the invention Give consumers a solid preparation.

Zu diesem Behufe bringt man ein entwässertes Aluminiumsalz, dessen saure Komponente stärker als Ameisensäure ist, mit ameisensaurem Natrium in molekularem, Verhältnis zusammen.For this purpose one brings a dehydrated aluminum salt, its acidic component is stronger than formic acid, with sodium formic acid in molecular, Relationship together.

Die Entwässerung der Ausgangsmaterialien, die übrigens keine vollständige zu sein braucht, erfolgt zweckmäßig durch Erwärmen im Vakuum. Sie ist erforderlich, um ein haltbares, klar wasserlöslich bleibendes Produkt zu erhalten.The drainage of the raw materials, which incidentally is not complete needs to be, is expediently done by heating in a vacuum. She is required in order to obtain a durable, clear water-soluble product.

Es war nicht zu erwarten, idaß die Entwässerung für das Haltbarmachen von Bedeutung. sein könnte, da die Ausgangsmaterialien, wie Alaun oder Aluminiumsulfat und ameisensaures Natrium, Verbindungen sind, die jede für sich beim Aufbewahren keine Veränderung erleiden, auch wenn sie nicht entwässert sind. Auch hätte man annehmen müssen, daß das ameisensaure Natrium, das verschiedene Moleküle Wasser binden kann, irgendwelche Unregelmäßigkeiten, die durch Wasserabspaltung aus dem Aluminiumsalz sich hätten ergeben können, von vornherein verhindert hätte.It was not to be expected that the drainage for preservation significant. could be as the starting materials, such as alum or aluminum sulfate and sodium formic acid, are compounds that are each used separately when stored do not suffer change even if they are not dehydrated. Also one would have must assume that the formic acid sodium, the various molecules of water can bind any irregularities caused by dehydration from the Aluminum salt could have arisen, would have prevented it from the start.

Gleichwohl hat sich herausgestellt, daß nicht entwässerte Ausgangsmaterialien kein auf die Dauer haltbares klar wasserlösliches -Produkt ergeben.Nevertheless, it has been found that starting materials that are not dehydrated do not result in a permanently stable, clear, water-soluble product.

Beispiel. Molekulare Mengen von Aluminiumsulfat und ameisensaurem Natrium werden zunächst einem Entwässerungsprozeß unterworfen, und zwar wird ameisensaures Natrium im Vakuum bei allmählich bis auf roo° ansteigender Temperatur z bis 2 Stunden lang erhitzt, während Aluminiumsulfat in der gleichen Weise so lange behandelt wird, bis etwa t2 Mal. Kristallwasser entfernt werden. Die so behandelten Materialien ergeben nach dem Zusammenmischen ein haltbares Produkt, das nach dem Eintragen in Wasser eine klare Lösung von ameisensaurer Tonerde entstehen IäBt, deren Konzentration der Verbraucher nach Belieben je nach dem Benutzungszweck bestimmen kann.Example. Molecular amounts of aluminum sulfate and formic acid Sodium is first subjected to a dehydration process, and it becomes formic acid Sodium in vacuum at gradually increasing up to roo ° temperature z heated for 2 hours, while aluminum sulfate was heated in the same way for so long treated until about t2 times. Water of crystallization can be removed. Those treated like that When mixed together, materials result in a durable product that after A clear solution of formic alumina is created by adding water to it, the concentration of which the consumer can determine at will, depending on the intended use can.
