Description
Verfahren zur Verbesserung der Löslichkeit von sauren Anthrachinonfarbstoffen Unter den sauren Anthrachi.nonfarbstoffen des Handels gibt es eine ganze Anzahl, die ungenügend löslich sind und bei der Anwendung in der Färberei und Druckerei Schwierigkeiten bereiten.Process for improving the solubility of anthraquinone acid dyes There are quite a number of the acidic anthrachi non-dyes on the market, which are insufficiently soluble and when used in dyeing and printing To cause difficulties.
Es wurde nun gefunden, daß .die Löslich- entspricht, worin Y OH, 1;H, oder durch Kohlenwasserstoffreste, die gegebenenfalls eine Sulfonsäure-gruppe tragen können, subkeit solcher Farbstoffe wesentlich verbessert werden kann, wenn man sie nach .den bekannten Methoden der Salzbildung in .die Lithiumsalze überführt. Für -das Verfahren eignen sich diejenigen Farbstoffe besonders gut, ,deren Aufbau der allgemeinen Zusammensetzung und stituiertes _NH" Y Wasserstoff oder Alkyl und Z Wasserstoff, Alky l oder Halogen, bedeuten. Die Verbesserung der Löslichkeit zugunsten der Lithiums.alze ist bemerkenszvert, indem sich von diesen in einer bestimmten Wassermenge zwei- bis fünfmal Es lösen sich in iooo Teilen kochendem Wasser Farbstoff' Natriumsalz I Lithiumsalz (Schultz-Farbstofftabellen, 7. Auflage, Nr. =Z96) (erhältl. nach Beispiel i der Patentschrift 131873) (erhältl. nachBeispiel i der Patentschrift 159 129) (erhältl. nach Beispiel 1 der Patentschrift 126 392) so viel löst als von den entsprechenden Natriumsalzen.It has now been found that the soluble corresponds, in which Y is OH, 1; H, or by hydrocarbon radicals, which can optionally carry a sulfonic acid group, the substance of such dyes can be significantly improved if they are converted into lithium salts by the known methods of salt formation. Those dyes are particularly suitable for the process, whose structure of the general composition and substituted _NH "Y denotes hydrogen or alkyl and Z denotes hydrogen, alkyl or halogen. The improvement in solubility in favor of the lithium salts is noteworthy, as they dissolve in a certain amount of water two to five times in 1,000 parts of boiling water Water dye 'sodium salt I lithium salt (Schultz color tables, 7th edition, no. = Z96) (obtainable according to example i of patent specification 131873) (obtainable according to example i of patent specification 159 129) (Obtainable according to Example 1 of patent specification 126 392) dissolves as much as of the corresponding sodium salts.
