Zusatz zum Patent 280505.Addendum to patent 280505.
Patentiert im Deutschen Reiche vom 28. April 1912 ab. Längste Dauer: 9. Januar 1927. Patented in the German Empire on April 28, 1912 . Longest duration: January 9, 1927.
Durch Patent 280505 ist ein Verfahren zur Darstellung von Chromverbindungen von Oxyanthrachinonsulfosäuren geschützt, welches darin besteht, daß man Oxyanthrachinonsulfosäuren oder deren Salze, bzw. Derivate dieser Verbindungen, mit Chromoxydsalzen in der Wärme behandelt.By patent 280505 is a method for the preparation of chromium compounds of oxyanthraquinone sulfonic acids protected, which consists in the fact that one Oxyanthraquinonesulfonic acids or their salts, or derivatives of these Compounds treated with chromium oxide salts in the heat.
Es wurde nun gefunden, daß es, sofern diese Verbindungen durch Eindampfen derIt has now been found that it, provided that these compounds by evaporation of the
• 10 Lösungen in konzentrierter Form erhalten werden sollen, unter Umständen, namentlich wenn das zur Darstellung der Chromverbindungen benutzte Chromoxydsalz sich von einer starken und schwerflüchtigen Mineralsäure ableitet, vorteilhaft ist, den Lösungen vor, während oder nach dem Eindampfen mineralsäurebindende Mittel zuzusetzen, da andernfalls die Chromverbindungen ganz oder teilweise zersetzt oder angegriffen werden können. Als solche Mittel seien z. B. Bisulfit, bei Anwendung von Fluorchrom auch Kieselsäure und kieselsäurehaltige Stoffe, wie Glaspulver, welche die Flußsäure unter Bildung von Kieselfluorwasserstoffsäure binden, genannt.• 10 solutions are to be obtained in concentrated form, under certain circumstances, specifically when the chromium oxide salt used to represent the chromium compounds differs from a strong and non-volatile mineral acid derives, it is advantageous to add mineral acid binding agents to the solutions before, during or after evaporation, otherwise the chromium compounds will be completely or partially decomposed or attacked can be. Such means are z. B. bisulfite, when using fluorochrome too Silicic acid and silicic acid-containing substances, such as glass powder, which form hydrofluoric acid bind of silicofluoric acid, called.
Ein Gemisch aus 10 Teilen hexaoxyanthrachinondisulfosaurem Natrium (erhältlich nach dem Verfahren der Patentschrift 75490, Kl. 22), 20 Teilen Fluorchrom und 600 Teilen Wasser wird zum Sieden erhitzt. Man fügt noch 2,5Teile Glaspulver hinzu und dampft die Lösung im Laufe von mehreren Stunden so weit ein, daß das Gesamtgewicht 50 Teilen entspricht. Nach dem Erkalten trennt man von dem Niederschlag, welcher größtenteils aus anorganischen Salzen besteht, und erhält eine Lösung, welche auch bei wochenlangem Stehen keinen Niederschlag absetzt.A mixture of 10 parts of hexaoxyanthraquinone disulfonic acid Sodium (obtainable by the process of patent specification 75490, class 22), 20 parts of fluorochrome and 600 parts of water are heated to the boil. Another 2.5 parts are added Add glass powder and evaporate the solution over the course of several hours until that the total weight corresponds to 50 parts. After cooling down, you separate from that Precipitate, which consists largely of inorganic salts, and receives a solution, which does not deposit any precipitation even when standing for weeks.
Anstatt Glaspulver kann man auch Kieselgur zusetzen oder z. B. in einem Glasgefäß arbeiten. Man kann ferner ohne Zusatz von kieselsäurehaltigen Substanzen im Bleikessel eindampfen und die fertige Lösung mit kieselsäurehaltigen Stoffen, gegebenenfalls in der Wärme, behandeln.Instead of glass powder you can also add kieselguhr or z. B. in a glass vessel work. You can also use the lead boiler without adding silicic acid-containing substances evaporate and the finished solution with silicic acid-containing substances, if necessary in the Heat, treat.
Ähnlich verfährt man bei Verwendung anderer mineralsäurebindender Mittel.A similar procedure is followed when using other mineral acid binding agents.
Ein Gemisch aus 10 Teilen hexaoxyanthrachinondisulfosaurem Natrium, 20 Teilen Fluorchrom und 600 Teilen Wasser wird mehrere Stunden zum Sieden erhitzt. Sodann dampft man unter allmählichem Zusatz von 15 Teilen Bisulfitlösung von 40 ° Be langsam so weit ein, daß das Gesamtgewicht 100 Teilen entspricht.A mixture of 10 parts of hexaoxyanthraquinone disulfonic acid Sodium, 20 parts of fluorochrome and 600 parts of water are heated to the boil for several hours. Then steams with the gradual addition of 15 parts of bisulfite solution of 40 ° Be slowly so far, that the total weight corresponds to 100 parts.
