Description
Verfahren zur Herstellung von gefärbten Desinfektionslösungen aus Fluor- und Kieselfluorverbindungen Die Durchführung von Desinfektionsarbeiten, insbesondere in der Gärungsindustrie, Nahrungsmittelfabrikation, Molkerei usw., litt bisher an dem Mangel, daß infolge der Farblosigkeit der Desinfektionsflüssigkeiten die Kontrolle der Arbeit schwierig und umständlich war, da sich nicht sofort durch den Augenschein feststellen ließ, ob die zu desinfizierenden Gefäße, wie Bottiche, Eimer, Lagergefäße, Rohrleitungen, mit den Desinfektionslösungen oder mit Wasser gefüllt waren.Process for the production of colored disinfectant solutions Fluorine and silica fluorine compounds The implementation of disinfection work, in particular in the fermentation industry, food processing, dairy, etc., so far suffered the lack of control due to the colorlessness of the disinfectant liquids The work was difficult and cumbersome as it wasn't immediately apparent determined whether the vessels to be disinfected, such as vats, buckets, storage vessels, Pipelines that were filled with disinfectant solutions or with water.
Im Gegensatz zu der Möglichkeit, aus neutralen Salzen bestehende Desinfektionsmittel und ihre Lösungen mit gebräuchlichen Farbstoffen zu färben, wie dies beispielsweise beim Sublimat mittels Eosin geschieht, scheitern bei stark sauren Verbindungen, wie den. Fluor- und Kieselfluorverbinduagen, bisher alle Versuche, aus diesen Verbindungen bestehende Desinfektionslösungen zu färben, entweder an der geringen Widerstandsfähigkeit der Farbstoffe, besonders bei längerer Einwirkungszeit, oder daran, daß die bei dem konzentrierten Präparat erzielte Färbung bei starker Verdünnung der Lösung verschwand. Es hat sich nun gezeigt, daß ein verhältnismäßig geringer Zusatz von Chromsäureanhydrid zu stark sauren konzentrierten Lösungen von Fluor- oder Fluorsiliciumpräparaten genügt, um auch .Lösungen der stärksten in der Praxis verwendeten Verdünnungen noch deutlich gelb zu färben. Ausführungsbeispiel Zu ioo Teilen Kieselfluorwasserstoffsäure vom spez. Gewicht 1,3 werden 2o Teile einer 5o°iaigen wäßrigen Lösung von Chromsäureanhydrid hinzugefügt. Eine aus i Teil dieser Mischung und 99 Teilen Wasser hergestellte Desinfektionslösung ist von deutlich gelber dauerhafter Färbung.In contrast to the possibility of disinfectants consisting of neutral salts and to color their solutions with common dyes, such as this for example happens with the sublimate by means of eosin, fail with strongly acidic compounds, like that. Fluorine and silica fluorine compounds, so far all attempts, from these compounds to color existing disinfectant solutions, either because of their low resistance of the dyes, especially with prolonged exposure time, or the fact that the with The color obtained with the concentrated preparation disappeared when the solution was greatly diluted. It has now been shown that a relatively small addition of chromic anhydride to strongly acidic concentrated solutions of fluorine or fluorosilicon preparations is sufficient to also .Solutions of the strongest dilutions still used in practice to be colored clearly yellow. Exemplary embodiment: To 100 parts of hydrofluoric acid from spec. Weight 1.3 is 2o parts of a 50 ° iaigen aqueous solution of chromic anhydride added. A disinfectant solution made from 1 part of this mixture and 99 parts of water is of a clearly yellow permanent color.
