Description

Herstellung von Farblacken. Es hat sich gezeigt, daß bei der Herstellung von Farblacken aus beliebigen anorganischen oder organischen Substraten einerseits und Lösungen von natürlichen oder künstlichen Farbstoffen andererseits eine sehr erhebliche Verbesserung der gewöhnlichen Verfahren erzielt werden kann, wenn man den Prozeß der Lackbildung in Gegenwart kleiner Mengen von im Kern substituierten wasserlöslichen Naphthalinsulfosäuren, deren Salzen oder sonstigen Derivaten vornimmt. Vorzugsweise verwendet man solche Verbindungen, welche als Substituenten drei- und mehratomige Alkyle enthalten.Manufacture of colored lacquers. It has been shown that in the production of colored lacquers from any inorganic or organic substrates on the one hand and solutions of natural or artificial colorants, on the other hand, very much Significant improvement in ordinary practice can be achieved if one the process of lacquer formation in the presence of small amounts of substituted in the core water-soluble naphthalene sulfonic acids, their salts or other derivatives. It is preferred to use compounds which have three and three substituents contain polyatomic alkyls.

Zur Durchführung des Verfahrens genügen bereits sehr geringe Mengen der Körper.Even very small amounts are sufficient to carry out the process the body.

Die Verbesserung besteht einerseits in einer Erhöhung der Absetz- und Filtriergeschwindigkeit, andererseits in einer erheblich weitergehenden Ausnutzung der Farblösungen durch restlose Ausfällung. Außerdem fallen die erhaltenen Farbtöne bedeutend frischer und leuchtender aus als ohne die erwähnten Zusätze. Ausführungsbeispiele.The improvement consists on the one hand in an increase in the and filtration speed, on the other hand in a considerably more extensive utilization of the color solutions through complete precipitation. In addition, the shades obtained fall Significantly fresher and brighter than without the additives mentioned. Embodiments.

i. Man löst 2o Teile Aluminiumsulfat in 8oo Teilen Wasser und fügt hierzu eine Lösung von io Teilen calcinierter Soda in ioo Teilen Wasser. Zu der so entstandenen Aufschlämmung von Tonerdehydrat in einer Lösung von Natriumsulfat werden unter Rühren io Teile Fuchsinlösung i : 5o, hierauf ein Teil isobutylnaphthalinsulfosaures Natron (in io Teilen Wasser) zugesetzt und mit 4.o Teilen Bariumchloridlösung i : io der Farbstoff und die Schwefelsäure gleichzeitig gefällt. Man erhält eine vollkommen wasserklare Lösung und einen rasch und vollständig absitzenden, vorzüglich filtrierbaren und im Farbton erheblich feurigeren Fuchsinlack als ohne den erwähnten Zusatz.i. 20 parts of aluminum sulfate are dissolved in 800 parts of water and added for this purpose a solution of 10 parts of calcined soda in 100 parts of water. To the The resulting slurry of alumina hydrate in a solution of sodium sulfate 10 parts of fuchsine solution i: 50, then one part of isobutylnaphthalenesulfonic acid are added with stirring Sodium bicarbonate (in 10 parts of water) was added and 4 parts of barium chloride solution were added : io the dye and the sulfuric acid precipitated at the same time. You get one perfectly water-clear solution and one that settles quickly and completely and is excellently filterable and fuchsine lacquer that is considerably more fiery in color than without the additive mentioned.

2. Man schlämmt Zoo Teile weißen Ton in 2ooo Teilen Wasser auf, befreit durch Kolieren von Klümpchen usw. und setzt unter gutem Rühren io Teile Methylenblau in Zoo Teilen Wasser und 2,5 Teile isopropylnaphthalinsulfosaures Natron in 25 Teilen Wasser hinzu. Für den Ausfall des Farblacks gilt das gleiche wie im Beispiel i.2. Zoo parts of white clay are slurried in 2,000 parts of water, freed by colicizing lumps, etc., and sets 10 parts of methylene blue with thorough stirring in zoo parts of water and 2.5 parts of isopropylnaphthalenesulfonate in 25 parts Add water. The same applies to the failure of the colored lacquer as in example i.

Die zur Durchführung des Verfahrens verwendeten Körper werden beispielsweise aus Betanaphthalinsulfosäure und Isobutylalkohol bzw. Isopropylalkohol durch Kondensation in Gegenwart von Schwefelsäure oder anderen Kondensationsmitteln hergestellt. Die Natriumsalze entstehen durch Neutralisation der Sulfosäuren.The bodies used to carry out the method are, for example from betanaphthalene sulfonic acid and isobutyl alcohol or isopropyl alcohol by condensation produced in the presence of sulfuric acid or other condensing agents. the Sodium salts are formed by neutralizing the sulfonic acids.
