Description
Verfahren zur Darstellung von Säurefarbstoffen der Anthrachinonreihe In dem Patent 462 799 ist die Herstellung von Thiomorpholinen der Anthrachinonreihe durch Behandeln von o-Aminoanthrachinonthiohydrinen mit sauren Kondensationsmitteln beschrieben. Die Produkte haben sich als wertvolle Farbstoffe, z. B. für Acetatseide, erwiesen.Process for the preparation of acid dyes of the anthraquinone series Patent 462,799 describes the preparation of thiomorpholines of the anthraquinone series by treating o-aminoanthraquinone thiohydrins with acidic condensing agents described. The products have proven to be valuable dyes, e.g. B. for acetate silk, proven.
Es wurde nun .gefunden, daß sich diese neuen Kondensationsprodukte sehr leicht sulfieren lassen und hierbei wertvolle Säurefarbstoffe liefern.It has now been found that these new condensation products Very easily sulfonate and thereby provide valuable acid dyes.
Beispiele. i. 5o Teile des aus o-Aminoanthrachinonäthylenthiöhydrin erhältlichen Thiomorpholins werden mit 25o Teilen Schwefelsäure 66° B6 und 25o Teilen Oleum 3oprozentig auf i3o bis 140' erhitzt, bis Wasserlöslichkeit eingetreten ist. Nach dem Eingießen in Wasser wird filtriert, mit Kochsalz neutral gewaschen und getrocknet. Der neue Farbstoff färbt auf Wolle in saurem Bade in kräftigen rotbraunen Tönen.Examples. i. 5o parts of the o-aminoanthraquinone ethyl thiohydrin available thiomorpholine with 25o parts of sulfuric acid 66 ° B6 and 25o parts Oleum heated to 30% to 140% until it became water-soluble. After pouring into water, it is filtered, washed neutral with sodium chloride and dried. The new dye dyes wool in an acidic bath in strong red-brown Tones.
In gleicher Weise lassen sich die Thiomorpholine aus; i . q.-Diamino-z-chlor-3-thiohydrinanthrachinon und aus 1 # 5-Diaminoanthrachinon-a # 6-dithiohydrin zu sauren Wollfarbstoffen sulfieren. Naturgemäß kann Ringschluß der o-Aninoanthrachinonthiohydrine zu Thiomorpholinen und nachträglicher S:ulfierung zu einer Operation vereinigt werden.The thiomorpholines can be omitted in the same way; i. Sulfate q.-diamino-z-chloro-3-thiohydrinanthraquinone and from 1 # 5-diaminoanthraquinone-a # 6-dithiohydrin to form acidic wool dyes. Of course, ring closure of the o-aminoanthraquinone thiohydrins to thiomorpholines and subsequent sulfation can be combined in one operation.
z. Man löst das in dem Patent 455 639 erwähnte i-Amino-¢-p-tolu@doanthrachinona-thiohydrin in der fünf- bis zehnfachen Menge aoprozentigem Oleum und .erhitzt auf So bis 9o°, bis Wasserlöslichkeit eingetreten ist. Hierbei .geht die anfangs violette Lösungsfarbe in eine graublaue über. Neben der Sulfierung ist offenbar ,gleichzeitig Ringschluß eingetreten.z. The i-amino- [-p-tolu @ doanthraquinona-thiohydrin mentioned in the patent 455,639 is dissolved in five to ten times the amount of non-alcoholic oleum and heated to so to 90 °, until water solubility has occurred. The initially violet solution color goes here into a gray-blue over. In addition to the sulphonation, ring closure is evidently carried out at the same time occurred.
Der in üblicher Weise isolierte Farbstoff färbt auf Wolle aus saurem Bade in grünen Tönen.The dye, isolated in the usual way, dyes wool from acid Bathe in green tones.
