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.

 

Claims (1)

PATENTANSPRUCH: Verfahren zur Darstellung eines neuen Küpenfarbstoffes der Anthrachinonreihe, da durch gekennzeichnet, dass man das Karb- azolderivat. aus Trichloranthrachinonakridon, erhältlich durch Chlorieren von Anthrachinon- 1.2-akridon in Nitrobenzol, und 1-Benzoyl- amido-4-amidoanthrachinon mit einem versei- fenden Mittel behandelt. PATENT CLAIM: Process for the preparation of a new vat dye of the anthraquinone series, characterized by the fact that one uses the carbazole derivative. from trichloroanthraquinone acridone, obtainable by chlorinating anthraquinone-1,2-acridone in nitrobenzene, and 1-benzoylamido-4-amidoanthraquinone treated with a saponifying agent. Das neue Produkt bildet graublaue Flocken und färbt aus gelbbrauner Küpe Baumwolle in braunen Tönen an, die beim Verhängen an der Luft in ein kräftiges Graublau über gehen. UNTERANSPRUCH: Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass man ein Karbazolderivat verwendet, das aus den Ausgangskomponen ten in einem Arbeitsgang mit der Verseifung hergestellt wurde. The new product forms gray-blue flakes and dyes cotton from a yellow-brown vat in brown tones, which turn into a strong gray-blue when hung in the air. SUBCLAIM: Process according to claim, characterized in that a carbazole derivative is used which was produced from the initial components in one operation with the saponification.
