Verfahren zur Darstellung grauer Farbstoffe der Anthrazenreihe.
In den Patentschriften Nr. 12577 und Nr. 14439 sind blaue und gelbe Farbstoffe beschrieben, welche aus ss-Amidoanthrachinon durch Oxydation resp. durch Verschmelzen mit kaustischem Kali entstehen. Solche Farbstoffe kommen unter den Namen Indanthren und Flavanthren in den Handel. Dieselben lassen sich nur durch Zuhilfenahme eigener Färbe-und Druckverfahren anwenden, die in den Patentschriften Nr. 14787 und Nr. 19140 beschrieben sind.
Es hat sich nun gezeigt, dass man Farbstoffe von blaugrauen bis rötlichgrauen Nuancen erhält, die nach denselben Verfahren gedruckt und gefärbt werden können, wenn man die Diamidoanthrachinone 1-5, 1-8,1-3, 2-6 und 2-7 mit kaustischem Kali verschmilzt.
Diese Farbstoffe besitzen bis auf die Nuancen dieselben Eigenschaften wie Indanthren und gehören offenbar derselben Klasse, nämlich den Anthrachinonazinen an. Wie die Indanthrene besitzen sie Echtheitseigenschaften, die diejenigen aller bekannten Farbstoffe übertreffen.
Beispiel I. 300 kg kaustisches Kali werden geschmolzen, dann werden bei 1800 C 100 f 1-5-Diamidoanthrachinon langsam eingetragen. Man erhitzt noch eine Stunde auf 1 !) () -2000 C. Man giesst in Wasser, kocht auf und filtriert.
Die anderen Diamidoanthrachinone werden in gleicher Weise verschmolzen. Man kann auch Mischungen der Diamidoanthrachinone sowie deren Sulfosäuren verwenden.
Die Farbstoffe bilden graurote bis grauolive Pasten, im trockenen Zustand schwarze
EMI1.1
säure lösen sie sich mit olivebrauner Farbe auf. Sie bilden alle mit Reduktionsmitteln in Gegenwart von kaustischen Alkalien eine braune Küpe, welche die vegetabilische Faser direkt anfärbt. Die Farbstoffe aus 1-5-und 1-8-Diamidoanthrachinon geben rötlichgraue, diejenigen aus 1-3, 2-6 und 2-7 grünlichgraue Färbungen.
Beispiel 11. In 350 kg kaustisches Kali werden bei 1700 C 100 kg 1-5-diamidoanthrachinonsulfosaures Natrium unter Rühren langsam eingetragen, wobei Schäumen der Schmelze eintritt. Nachdem dieses nachgelassen hat, heizt man noch zig Stunden auf
EMI1.2
filtriert und gewaschen. Analog verfährt man bei der Anwendung anderer Diamidoanthrachinonsulfosäuren.
Die Farbstoffe aus den Diamidoanthrachinonsulfosäuren bilden in trockenem Zustande hraunschwarze Pulver und zeigen im wesentlichen dieselben Eigenschaften, w. dite aus den unsulfiorton Diamidokürpern dargestellten.

Process for the preparation of gray dyes of the anthracene series.
In the patent specifications No. 12577 and No. 14439 blue and yellow dyes are described, which are obtained from β-amidoanthraquinone by oxidation, respectively. by fusing with caustic potash. Such dyes are marketed under the names indanthrene and flavanthrene. These can only be used with the aid of our own dyeing and printing processes, which are described in patent specifications No. 14787 and No. 19140.
It has now been shown that dyes of blue-gray to reddish-gray shades can be obtained, which can be printed and colored by the same method if the diamidoanthraquinones 1-5, 1-8,1-3, 2-6 and 2-7 are used with caustic potash fuses.
Except for the nuances, these dyes have the same properties as indanthrene and apparently belong to the same class, namely the anthraquinone azines. Like the indanthrenes, they have fastness properties that exceed those of all known dyes.
Example I. 300 kg of caustic potash are melted, then 100 f 1-5-diamidoanthraquinone are slowly introduced at 1800 C. It is heated to 1!) () -2000 C. for a further hour. It is poured into water, boiled and filtered.
The other diamido anthraquinones are fused in the same way. Mixtures of the diamidoanthraquinones and their sulfonic acids can also be used.
The dyes form gray-red to gray-olive pastes, black when dry
EMI1.1
acid dissolve with olive brown color. They all form a brown vat with reducing agents in the presence of caustic alkalis, which directly stains the vegetable fibers. The dyes from 1-5- and 1-8-diamidoanthraquinone give reddish-gray, those from 1-3, 2-6 and 2-7 greenish-gray.
Example 11. 100 kg of 1-5-diamidoanthraquinonesulphonate sodium are slowly introduced into 350 kg of caustic potash at 1700 ° C. with stirring, the melt foaming. After this has subsided, you heat up for tens of hours
EMI1.2
filtered and washed. The same procedure is used when using other diamidoanthraquinone sulfonic acids.
The dyes from the diamidoanthraquinone sulfonic acids form gray-black powders in the dry state and show essentially the same properties, w. dite depicted from the unsulfiorton diamido bodies.
