Description

Verfahren zur Herstellung kolloidaler Metalle oder deren Verbindungen.Process for the production of colloidal metals or their compounds.

Es wurde gefunden, daß diejcnigen Produkte, welche bei der Behandlung von Sulfitablauge mit Halogen oder Halogen entwickelnden Substanzen entstehen, ausgezeichnete Schutzkolloide sind und daher bei der Herstellung kolloidaler Metalle oder deren Verbindungen Anwendung finden können. Fällt man z. B. ein Metall oder eine Metaliverbindung aus deren Lösungen durch ein Fällungsmittel bei Gegenwart dieser Substanzen aus, so bleibt die Verbindung kolloidal gelöst. It has been found that the products used in the treatment from sulphite waste liquor with halogen or halogen-evolving substances are excellent Protective colloids are and are therefore used in the production of colloidal metals or their Connections can be used. If you fall z. B. a metal or a metal compound from their solutions by a precipitant in the presence of these substances, so the connection remains colloidally dissolved.

Vor der bisher als Schutzkolloid vorgeschlagenen Sulfitablauge haben vorliegende Produkte den Vorzug, daß dieselben für sich allein schon bakterizide Eigenschaften haben, was, da kolloidale Metallverbindungen meist therapeutische Anwendung finden, zu einer Verstärkung der beabsichtigten Wirkung führt. Before the sulphite liquor previously proposed as a protective colloid have present products have the advantage that they are bactericidal in their own right Properties have what, since colloidal metal compounds are mostly therapeutic Apply, leads to an intensification of the intended effect.

Die durch Einwirkung von Halogen oder Halogen entwickelnden Substanzen auf Sulfitablauge erhaltenen Produktc können beispielsweise wie folgt dargestellt werden: Sulfitablauge von 250 Be wird so lange mit Chlor behandelt, bis das sich ausscheidende Chlorierungsprodukt einen Gehalt von 20 bis 25 Prozent C1 aufweist. Der abgetrennteNiederschlag kann entweder als solcher verwendet werden, oder er wird in Salzsäure suspendiert und mit Kaliumchlorat nachbehandelt. Das auf diese Weise erhaltene Produkt weist einen höheren Chlorgehalt, etwa 27 bis 29 Prozent C1, auf. The substances evolving through the action of halogen or halogen Products obtained on sulphite waste liquor can be represented, for example, as follows be: Sulphite waste liquor of 250 Be is treated with chlorine until the The chlorination product which separates out has a content of 20 to 25 percent C1. The separated precipitate can be used either as such or it is suspended in hydrochloric acid and treated with potassium chlorate. That on this Well-obtained product has a higher chlorine content, about 27 to 29 percent C1, on.

Die Produkte stellen gelbe bis gelbbraun gefärbte Verbindungen dar, die mehr oder weniger in Wasser löslich sind. The products represent yellow to yellow-brown colored compounds, which are more or less soluble in water.

Beispiel I. Example I.

Fehlingsche Lösung wird mit so viel eines durch Einwirkung von Chlor auf Sulfitlauge erhältlichen Produktes versetzt, daß noch schwach alkalische Reaktion vorhanden ist. Fehling's solution becomes one with so much through the action of chlorine on sulfite liquor available product added that still weakly alkaline reaction is available.

Die so erhaltene Lösung wird entweder für sich oder nach Zugabe von Traubenzucker erhitzt. Das ausscheidende Kupfer bleibt kolloidal gelöst.The solution thus obtained is either by itself or after adding Heated glucose. The precipitating copper remains colloidally dissolved.

Beispiel II. Example II.

Zu einer Lösung von 10 Teilen eines durch C2hlorierung von Sulfitablauge erhaltenen Produktes in 200 Teilen Wasser werden t i Teile Wismutchlorid und so viel Salzsäure zugefügt, daß klare Lösung eintritt. Diese Lösung wird unter Rühren in eine Lösung von lo Teilen desselben Cblorierungsproduktes in 200 Teilen Wasser und 25 Teilen Ätznatron gegeben. Die erhaltene Lösung wird bis zur Lakmusneutralltät dialysiert und hierauf zur Trockene verdampft. Man erhält ein in Wasser klar lösliches dunkelbraunes Produkt mit einem Wismutgehalt von 45 bis 47 Prozent. To a solution of 10 parts by chlorination of sulphite waste liquor obtained product in 200 parts of water are t i parts of bismuth chloride and so on a lot of hydrochloric acid added so that a clear solution occurs. This solution is stirring into a solution of 10 parts of the same chlorination product in 200 parts of water and 25 parts of caustic soda. The solution obtained is neutral to lacmus dialyzed and then evaporated to dryness. A solution which is clearly soluble in water is obtained dark brown product with a bismuth content of 45 to 47 percent.

Beispiel III. Example III.

40 g eines durch Einwirkung von Chlor auf Sulfitablauge erhältlichen Produktes werden zusammen mit 4 g Kupfersulfat in Wasser gelöst. Die Lösung wird unter Rühren mit so viel Natronlauge versetzt, bis schwad alkalische Reaktion auftritt. Das sich bildende Kupferhydroxyd bleibt kolloidal gelöst. Die Lösung kann zur Trockene eingedampft werden. Das auf diese Weise erhältliche Produkt ist in Wasser leicht löslich. 40 g of one obtainable by the action of chlorine on sulphite waste liquor Product are dissolved in water together with 4 g of copper sulfate. The solution will be Sufficient sodium hydroxide solution is added while stirring until an alkaline reaction occurs. The copper hydroxide that forms remains colloidally dissolved. The solution can become dry be evaporated. The product obtainable in this way is light in water soluble.
