Description
Verfahren zur Herstellung von kolloiden Lösungen von Metallen, Metallverbindungen und Metalloiden in Glycerin oder anderen Polyalkoholen Zusatz zum Patent 6oi 957 Zur Herstellung kolloide Lösungen von Metallen, Metallverbindungen und Metalloiden in Glycerin oder anderen Polyalkoholen ist vorgeschlagen worden, die Kolloide im Glycerin oder anderen Polyalkoholen in Gegenwart reversibler organischer Kolloide vom Gummi- bzw. Eiweißtypus entstehen zu lassen oder sie zunächst in leicht flüchtigen Dispersionsmitteln herzustellen, darauf die Lösungen mit Glycerin oder anderen Polgalkoholen zu vermischen und schließlich die flüchtigen Lösungsmittel zu entfernen. Weiter ist es zur Erzielung des gleichen Zweckes vorgeschlagen worden, die in den kolloiden Zustand überzuführenden Stoffe mit den gleichen Schutzkolloiden und mit Glycerin oder anderen Polyalkoholen, gegebenenfalls in Gegenwart von Stoffen, die Lösungsmittel für die zu dispergierenden Stoffe darstellen, zu vermahlen. Die so erhältlichen Zubereitungen sind Flüssigkeiten, die je nach Gehalt an dispergierten Stoffen mehr oder wenig dickflüssig ausfallen.Process for the preparation of colloidal solutions of metals, metal compounds and metalloids in glycerine or other polyalcohols. Addition to patent 6oi 957 For the production of colloidal solutions of metals, metal compounds and metalloids in glycerol or other polyalcohols it has been suggested that the colloids im Glycerine or other polyalcohols in the presence of reversible organic colloids of the rubber or protein type or initially in the form of volatile ones Prepare dispersants, then add solutions with glycerine or other polyalcohols to mix and finally to remove the volatile solvents. Further it has been suggested to achieve the same purpose that in the colloidal State to be transferred substances with the same protective colloids and with glycerine or other polyalcohols, optionally in the presence of substances, the solvents represent for the substances to be dispersed, to be ground. The so available Preparations are liquids that, depending on the content of dispersed substances, more or are not very viscous.
Vielfach liegt nun das Bedürfnis vor, derartige kolloide Lösungen in trockener bzw. fester Form zu erhalten. Dies ist besonders dann der Fall, wenn es sich um die Verpakkung handelt. Für manche- Zwecke, z. B. für den Versand von Badepräparaten sind Behälter aus Glas, Steingut, Ton usw. zu teuer. In many cases, there is now a need for such colloidal solutions in dry or solid form. This is especially the case when it is about the packaging. For some purposes, e.g. B. for the shipment of Bath preparations, containers made of glass, earthenware, clay, etc. are too expensive.
Man bevorzugt in solchen Fällen Beutel oder Tüten.Bags or sachets are preferred in such cases.
Es wurde nun gefunden, daß man zu kolloiden Lösungen von Metallen, Metallverbindungen und Metalloiden in Glycerin oder anderen Polyalkoholen in fiester Form gelangt, die den Vorteil einer außerordentlich leichten Löslichkeit besitzen, wenn man nach den oben beschriebenen Verfahren arbeitet, dabei aber nur so wenig Glycerin bzw. andere Polyalkohole verwendet, daß die Zubereitungen in fester oder sogar pulverförmiger Form erhalten werden. Es war keinesfalls vorauszusehen, daß bei Anwendung so geringer Mengen von Dispersionsmitteln, es genügen beispielsweise 5 bis Io °Io Glycerin oder andere Polyalkohole, kolloide Lösungen erhalten würden. It has now been found that colloidal solutions of metals Metal compounds and metalloids in glycerine or other polyalcohols in solid Form which have the advantage of extremely easy solubility, if you work according to the methods described above, but only so little Glycerin or other polyalcohols used that the preparations in solid or even powder form can be obtained. It was by no means foreseeable that if such small amounts of dispersants are used, it will suffice, for example 5 to Io ° Io glycerine or other polyalcohols, colloidal solutions would be obtained.
Beispiel I IooTeile einer io0J0igen Lösung eines durch alkalische Spaltungsprodukte von Eiweißstoffen stabilisierten Silbers versetzt man mit t/2 bis 1 Teil Glycerin oder einem anderen Polyalkohol und entfernt das Wasser. Example I 100 parts of a 100% solution of an alkaline Cleavage products of protein substances stabilized silver one with t / 2 to 1 part glycerine or another polyalcohol and removes that Water.
Beispiel 2 0,9 kg Schwefelblume werden mit 1,1 kg eines durch alkalische Spaltung von Casein erhaltenen Spaltungsproduktes in einer Kugelmühle, gegebenenfalls unter Zusatz von 100 bis 200 g Alkohol, längere Zeit vermahlen. Example 2 0.9 kg of sulfur flowers with 1.1 kg of an alkaline Cleavage of casein obtained cleavage product in a ball mill, if necessary grind for a long time with the addition of 100 to 200 g of alcohol.
Man läßt dann den Alkohol verdunsten und vermahlt weiter mit I00 g Glycerin noch I bis 2 Tage. Man erhält ein außerordentlich leicht kolloidlösliches Schxvefelpräparat in fester Form.The alcohol is then allowed to evaporate and a further 100 g is milled Glycerine for 1 to 2 days. An extremely readily colloid-soluble one is obtained Schxvefel preparation in solid form.
Beispiel 3 70 Teile Eisenoxyd, welches möglichst feinkörnig sein soll, vermahlt man mit 25 Teilen Gummiarabikum, 5 Teilen Glycerin und 60 Teilen Wasser mehrere Tage. Die erhaltene kolloide Lösung wird eingetrocknet. Example 3 70 parts of iron oxide, which should be as fine-grained as possible is to be ground with 25 parts of gum arabic, 5 parts of glycerine and 60 parts Water for several days. The colloidal solution obtained is dried.
Die nach vorliegendem Verfahren hergestellten Glycerinkolloide in fester Form zeichnen sich gegenüber anderen kolloiden Trockenpräparaten durch ihre besondere Löslichkeit aus. The glycerol colloids produced by the present process in solid form stand out from other colloidal dry preparations by their particular solubility.
