Description
Verfahren zur Darstellung eines neuen Küpenfarbstoffes der Anthrachinonreihe. Im Hauptpatent ist ein Verfahren zur Darstellung eines neuen Küpenfarbstoffes der Anthrachitionreihe beschrieben, das dadurch gekennzeichnet ist, dass man das Karbazol- derivat aus Trichloranthrachirionakridon, er hältlich durch Chlorieren von Antbrachinon- 1 .
2-akridon in Nitrobenzol, und 1-Benzoyla- inido-5-amidoanthrachinon mit einem versei- fenden Mittel behandelt.
Gegenstand vorliegender Erfindung ist ein Verfahren zur Darstellung eines neuen Küpen- farbstoffes der Anthrachinonreihe, dadurch gekennzeichnet, dass man das Karbazolderivat aus Trichloranthrachinonakridon, erhältlich durch Chlorieren von Anthrachinon-1.2-akri- don in Nitrobenzol, und 1-Benzoylamido-4- amidoantbrachinon mit einem verseifenden Mittel behandelt.
Hierbei kann man auch ein solches Karb- azolderivat verwenden, das aus den Aus gangskomponenten im gleichen Arbeitsgang mit der Verseifung gewonnen wurde. <I>Beispiel:</I> 3 Gewichtsteile des aus Trichloranthra- chinonakridori, erhältlich durch Chlorieren von Anthrachinon-1.2-akridori in Nitroben- zol, und 1-Benzoylaniino-4-amidoanthrachitiou erhältlichen Karbazolderivates werden in 30 Gewichtsteilen konzentrierter Schwefelsäure längere Zeit auf 80-90 erwärmt,
bis sich eine Probe in Schwefelsäure nicht mehr graublau, sondern schmutzig rot löst. Die Schmelze wird dann in Wasser gegossen, aufgekocht, filtriert und der Rückstand neu tral gewaschen. Man erhält den Farbstoff in graublauen Flocken. Der Körper färbt aus gelbbrauner Küpe Baumwolle in braunen Tönen an, die beim Verhängen an der Luft in ein kräftiges Blaugrau übergehen.
Process for the preparation of a new vat dye of the anthraquinone series. The main patent describes a process for the preparation of a new vat dye of the anthraquinone series, which is characterized in that the carbazole derivative is obtained from trichloroanthraquinone acridone, which can be obtained by chlorinating anthraquinone-1.
2-akridon in nitrobenzene, and 1-benzoylaynido-5-amidoanthraquinone treated with a saponifying agent.
The present invention is a process for the preparation of a new vat dye of the anthraquinone series, characterized in that the carbazole derivative from trichloroanthraquinone acridone, obtainable by chlorinating anthraquinone-1,2-acridone in nitrobenzene, and 1-benzoylamido-4-amidoantbrachinone with a saponifying agents treated.
It is also possible to use a carbazole derivative that was obtained from the starting components in the same operation as the saponification. <I> Example: </I> 3 parts by weight of the carbazole derivative obtainable from trichloroanthraquinone acridori, obtainable by chlorinating anthraquinone-1,2-akridori in nitrobenzene, and 1-benzoylaniino-4-amidoanthrachite derivative obtainable in 30 parts by weight of concentrated sulfuric acid 80-90 heated,
until a sample in sulfuric acid no longer dissolves gray-blue, but dirty red. The melt is then poured into water, boiled up, filtered and the residue washed neutral. The dye is obtained in gray-blue flakes. The body dyes cotton from a yellow-brown vat in brown tones, which turn into a strong blue-gray when hanging in the air.
