Description
Verfahren zur Herstellung haltbarer wäßriger Lösungen von Silbernatriumthiosulfat (2 Na-. SE 03 ' Ag2 S2 03 . 2 H2 0) für therapeutische _ Zwecke Leicht lösliches Silbernatriumthiosulfat hat sich bei der Behandlung von Infektionen gut bewährt.A process for preparing aqueous solutions of durable Silbernatriumthiosulfat (2 Na. SE 03 'Ag2 S2 03. 2 H2 0) soluble for therapeutic purposes light _ Silbernatriumthiosulfat have proven very effective in the treatment of infections.
In wäßriger Lösung ist es jedoch nicht haltbar, da nach einiger Zeit sich Silbersulfid abscheidet. Es hat sich nun herausgestellt, daß man die wäßrigen Lösungen des Silbernatriumthiosulfats haltbar machen kann, wenn man ihnen wasserlösliche, alkalisch reagierende Salze zusetzt.However, it cannot be kept in an aqueous solution because it does so after a while silver sulfide is deposited. It has now been found that the aqueous Solutions of silver sodium thiosulphate can be preserved if they are water-soluble, Adds alkaline salts.
Beispiel i i g Silbernatriumthiosulfat wird in ioo ccm Wasser gelöst und der Lösung o,5 g Natriumbicarbonat oder Natriumcarbonat zugesetzt. Diese Lösung hält sich monatelang ohne jede Zersetzung, während aus der reinen Silbernatriumthiosulfatlösung sich nach etwa io Tagen Silbersulfid abscheidet.Example i i g of silver sodium thiosulphate is dissolved in 100 cc of water and 0.5 g of sodium bicarbonate or sodium carbonate were added to the solution. This solution lasts for months without any decomposition, while from the pure silver sodium thiosulphate solution silver sulfide separates after about 10 days.
Beispiel e 5 g Silbernatriumthiosulfat werden in 'ioo ccm Wasser gelöst und mit i g sekundärem Natriumphosphat versetzt. Beispiel 3 2 g Silbernatriumthiosulfat werden in i oo ccm Wasser gelöst und mit 0,5.-. Borax versetzt. Beispiel q.Example e 5 g of silver sodium thiosulfate are dissolved in 100 cc of water and mixed with i g of secondary sodium phosphate. Example 3 2 g of silver sodium thiosulfate are dissolved in 100 ccm of water and with 0.5.-. Borax offset. Example q.
2 g Silbernatriumthiosulfat werden in ioo ccm Wasser gelöst und durch Zusatz von o,2 g Natriumcarbonat haltbar gemacht.2 g of silver sodium thiosulphate are dissolved in 100 cc of water and poured through Addition of 0.2 g of sodium carbonate made durable.
Die Zusammensetzung des Silbernatriumthiosulfats ist 2 Na. S20,# Ag_SO@ # 2 H20. Die verwendeten Stoffe lassen- sich auch, wenn Sie trocken miteinander gemischt sind, durch gemeinsames Lösen in Wasser in haltbare Lösungen überführen.The composition of the silver sodium thiosulfate is 2 Na. S20, # Ag_SO @ # 2 H20. The fabrics used can also be used when dry with one another are mixed, convert into durable solutions by dissolving them together in water.
