Description
Verfahren zur Herstellung haltbarer Desinfektionsmittel Die desinfizierende Wirkung von Rhodanwasserstoffsäurelösungen bzw. sauren Rhodanidlösungen ist bekannt. Ihre Haltbarkeit selbst in stark verdünnter Lösung ist begrenzt: Es treten Gerüche insbesondere auch nach Schwefelwasserstoff auf, die ihrer Verwendung entgegenstehen. Man hat deshalb bereits vorgeschlagen, sauren Rbodanidlösungen solche Metalle bzw. Metallverbindungen zuzusetzen welche die Schwefelwasserstoffentwicklung verhindern. Weiterhin wird ein Verfahren zur Herstellung haltbarer viskoser, saurer Rhodanidlösungen mittels Tragant beschrieben. Diese Verfahren haben den Nachteil, daß die Lösungen unansehnlich werden.Process for making durable disinfectants The disinfectant The effect of hydrofluoric acid solutions or acidic rhodanide solutions is known. Their shelf life is limited, even in very dilute solutions: there are smells especially after hydrogen sulfide, which oppose their use. It has therefore already been proposed to use acidic rbodanide solutions such metals or Add metal compounds which prevent the development of hydrogen sulfide. Furthermore, a process for the production of durable, viscous, acidic rhodanide solutions is disclosed described by means of tragacanth. These methods have the disadvantage that the solutions become unsightly.
Überraschenderweise 'at sich .die Mittverwendung von Natriumsilicatlösungen bei Herstellung @-on sauren Rhodanidlösungen als besonders günstig erwiesen, da sie diesen Nachteil nicht aufweisen. Stellt man 'beispielsweise eine Lösung mit einem pH-Wert von etwa 1,2 und einem Rhodanionengehalt von etwa 4,8% mittels Lösungen von Schwefelsäure, Natriumsilicat und Ammonrhodanid her, so entstehen zunächst Kieselsäuresole, die erst nach mehreren Tagen zu einer Gallerte erstarren. Die Erstarrungsgeschwindigkeit kann man je nach Konzentration oder durch Zusätze, beispielsweise durch Ampholyte oder bzw. und Elektrolyte erhöhen oder auch erheblich verlangsamen und so die gewonnenen Erzeugnisse verschiedenen Zwecken anpassen.Surprisingly, it is possible to use sodium silicate solutions in the production of @ -on acidic rhodanide solutions proved to be particularly favorable, since they do not have this disadvantage. For example, if you provide a solution with a pH of about 1.2 and a rhodium anion content of about 4.8% by means of solutions from sulfuric acid, sodium silicate and ammonium rhodanide, this is how silica sols are first formed, which only solidify into a jelly after several days. The rate of freezing depending on the concentration or through additives, for example ampholytes or and / or and electrolytes increase or also slow down considerably and so the gained Adapt products for different purposes.
Beispiel -Man bringt eine Lösung von i i io ccm Natriumsilicat, die einem Gehalt von etwa 8o g Natriumhydroxyd entspricht, mit 1317 ccm 27%iger Schwefelsäure zur Reaktion und fügt 966 ccm einer 6o,6volumprozen,tigen Ammonrhodanidlösung als weitere Reaktionskomponente hinzu.Example -Man brings a solution of i i io ccm of sodium silicate that corresponds to a content of about 80 g of sodium hydroxide, with 1317 ccm of 27% sulfuric acid to the reaction and adds 966 cc 6o, 6volumprozen, term ammonrhodanide solution added as a further reaction component.
Das Reaktionsgemisch ergibt eine klare homogene Lösung, die. erst nach einigen Tagen erstarrt. i@ian hat es in der Hand, die Lösung in `Gefäße abzufüllen und in ihnen die Erstarrung abzuwarten. Die erstarrte Lösung zeigt überraschenderweise einen höheren Säuretiter als vor der Erstarrung und bietet für die Stabilisierung des PH-Wertes ausreichende Sicherheit. Verwendet man so :hergestellte Lösungen zur Händedesinfektion, so wird der biologische Säureschutz der Haut längere Zeit hindurch erhöht. Letzteres wird noch günstiger gestaltet, wenn man der Lösung zweckmäßig vor der Erstarrung Rhodanwasserstoffsäure bindende Substanzen, wie beispielsweise Betain, Eiweiß'hydrolysate und/oder auch Harnstoff, hinzufügt. ZurDesinfektion von Wäsche, Verbandstoffen od. dgl. sind diese auswaschbaren Erzeugnisse ebenfalls ,gut geeignet. Die ausreichend erstarrten Lösungen können zerkrümelt «erden und eignen sich zur Verpackung z. B. in lackierten Pappdosen. Die nach beschriebenem Verfahren hergestellten Erzeugnisse benötigen im Gegensatz zu den bisher bekannten, besonders bei Zuführung von Luftsauerstoff, keinen Zusatz von Metallen und Metallverbindungen zur Bindung des Schwefelwasserstoffes.The reaction mixture gives a clear homogeneous solution which. first solidified after a few days. It is up to i @ ian to fill the solution into `vessels and wait to be frozen in them. The solidified solution surprisingly shows a higher acid titer than before solidification and provides for stabilization adequate security of the pH value. If you use it like this: manufactured solutions for Hand disinfection is how the skin's biological acid protection lasts for a long time elevated. The latter is made even cheaper if the solution is expedient substances that bind hydrofluoric acid prior to solidification, such as, for example Betaine, protein hydrolysates and / or urea added. For disinfecting Linen, bandages or the like, these washable products are also good suitable. The sufficiently solidified solutions can be crumbled and suitable for packaging z. B. in lacquered cardboard cans. The according to the procedure described manufactured products need in contrast to the previously known, especially with supply of atmospheric oxygen, no addition of metals and metal compounds to bind the hydrogen sulfide.
