Description

Verfahren zur Darstellung einer leicht löslichen komplexen Silberverbindung Im Jahre 18¢ 1 hat L e n z (Liebigs Annalen Bd. 40, S. 94) durch Einwirkung von Chlorsilber auf 'atriumthiosulfat bzw. durch Einwirkung von Silbernitrat auf Natriumthiosulfat eine Verbindung der Formel Ag2S203 # z Na. S203 2 H20 hergestellt; jedoch ist die Darstellung über das Chlorsilber umständlich; es entstehen, wie Rosenheim und Steinhauer in der Zeitschrift für anorganische Chemie (Bd. 25, S. 73) nachgewiesen haben. nebenbei auch andere schwer lösliche Verbindungen. Durch Einwirkung von Silbernitrat auf 'atriumthiosulfatlösungen konnten die genannten Autoren überhaupt die Lenzsche Verbindung nicht herstellen.Process for the preparation of an easily soluble complex silver compound In 18 ¢ 1 L e n z (Liebigs Annalen vol. 40, p. 94) through the action of Chloride of silver on atrium thiosulphate or by the action of silver nitrate on sodium thiosulphate a compound of the formula Ag2S203 # z Na. S203 2 H20 produced; however that is Representation via the chlorine silver cumbersome; it arise like Rosenheim and Steinhauer in the journal for inorganic chemistry (vol. 25, p. 73) have demonstrated. alongside also other poorly soluble compounds. By exposure to silver nitrate The authors mentioned were able to identify Lenz's compound at all not manufacture.

Diesen Befund haben die Untersuchungen des Anmelders bestiitigt. Es wurde jedoch überraschenderweise festgestellt, daß inan mit großer Leichtigkeit die gewünschte Verbindung aus Natriumthiosulfat und Silbernitrat herstellen kann, wenn man die -Umsetzung in Gegenwart von Chlor bzw. Bromnatrium ausführt.The applicant's investigations have confirmed this finding. It however, it was surprisingly found that inanan with great ease can produce the desired compound from sodium thiosulphate and silver nitrate, if the conversion is carried out in the presence of chlorine or sodium bromide.

Beispiel t.Example t.

G,3 Teile Natriumthiosulfat werden mit 1 Teil Kochsalz in 125 Tcilen Wasser gelöst; in diese Lösung werden unter schnellem Rühren 3 Teile Silbernitrat in wäßriger Lösung gegeben. Es findet sofort eine Umsetzung statt, und aus der blank filtrierten Lösung wird nach bekannten 'Methoden das Salz Ag2S203 z Na= S203 2 H20 abgeschieden. . Beispiel 2.G, 3 parts of sodium thiosulphate are dissolved with 1 part of common salt in 1 25 parts of water; 3 parts of silver nitrate in aqueous solution are added to this solution with rapid stirring. A reaction takes place immediately, and the salt Ag2S203 z Na = S203 2 H20 is deposited from the clear, filtered solution using known methods. . Example 2.

3 Teile Natritimtlliosulfat werden mit 1 Teil Bromnatrium in 25 Teilen Wasser gelöst; in diese Lösung werden 1,2 Teile Silbernitrat in wäßriger Lösung unter schnellem Rühren zugetan. 'ach stattgehabter Umsetzung wird aus der blank filtrierten Lösung die obergenannte Verbindung abgeschieden. Die Abscheidung des Silbernatriumthiosultats aus der Lösung erfolgt in an sich bekannter Weise, z. B. durch Fällen mit Alkohol.3 parts of sodium sulfate are mixed with 1 part of sodium bromide in 25 parts Dissolved water; 1.2 parts of silver nitrate in aqueous solution are in this solution added with rapid stirring. 'After implementation has taken place, the blank filtered solution deposited the above-mentioned compound. The deposition of the Silver sodium thiosultats from the solution is carried out in a manner known per se, e.g. B. by cases with alcohol.

Die -Verbindung hat die in der Literatur beschriebenen Eigenschaften. Sie soll therapeutische Verwendung finden.The compound has the properties described in the literature. It should find therapeutic use.
