Description

  

  Verfahren     zur    Darstellung eines     I±üpenfarbstoffes    der     Antluachinonreihe.       Im Hauptpatent ist ein Verfahren zur  Darstellung eines     Küpenfarbstoffes    beschrie  ben, bei dem 2.     1-(N)-Anthrachinonakridon-          6-karbonsäurechlorid    mit     1-Amino-4-methogy-          anthrachinon    durch Erhitzen in einem Lö  sungsmittel umgesetzt wird.  



  Es wurde nun gefunden, dass man in  ganz analoger Weise einen     güpenfarbstoff     von ähnlichen wertvollen Eigenschaften er  halten kann, wenn man     2.1-(S)-Anthra-          chinonthioganthon-Bz2-karbonsäurechlorid    von  der Formel  
EMI0001.0012     
    mit 1-     Amino    - 5 -     benzoylaminoanthrachinon     durch Erhitzen in einem Lösungsmittel kon  densiert.  



  <I>Beispiel:</I>  404 Teile     2.1-.(S)-Anthrachinonthioxan-          thon-Bz2-karbonsäurechlorid    der oben ange  gebenen Formel, hergestellt durch Konden  sation von     1-Chloranthrachinon-2-karbonsäure     mit     o-Merkaptobenzoesäure,        Ringschluss    mit       Essigsäureanhydrid    unter Zusatz von Schwe  felsäure und Überführung in das Säurechlorid  durch Behandeln mit     Thionylchlorid    in     o-Di-          chlorbenzol,    werden mit 343 Teilen     1-Amino-          5-benzoylaminoanthrachinon    in 10,

  000 Teilen       Nitrobenzol    so lange auf 180-185   C er  hitzt, bis die     Farbstoffbildung    beendet ist.  Man erhält einen     Farbstoff,    der sich in kon  zentrierter Schwefelsäure orangegelb löst und  aus der schwefelsauren Lösung durch Wasser  in goldgelben Flocken abgeschieden wird.  Er bildet eine dunkelviolette     güpe,    aus der      die Faser in klaren, goldgelben Tönen an  gefärbt wird.



  Process for the preparation of an anti-luachinone series dye. In the main patent, a process for the preparation of a vat dye is described ben in which 2. 1- (N) -Anthraquinone acridone-6-carboxylic acid chloride is reacted with 1-amino-4-methogy-anthraquinone by heating in a solvent.



  It has now been found that in a completely analogous manner, a high quality dye of similar valuable properties can be obtained if 2.1- (S) -Anthrachinonthioganthone-Bz2-carboxylic acid chloride of the formula
EMI0001.0012
    condensed with 1-amino-5-benzoylaminoanthraquinone by heating in a solvent.



  <I> Example: </I> 404 parts of 2.1 -. (S) -anthraquinone thioxanthone-Bz2-carboxylic acid chloride of the formula given above, produced by condensation of 1-chloroanthraquinone-2-carboxylic acid with o-mercaptobenzoic acid, ring closure with Acetic anhydride with the addition of sulfuric acid and conversion into the acid chloride by treatment with thionyl chloride in o-dichlorobenzene, with 343 parts of 1-amino-5-benzoylaminoanthraquinone in 10,

  000 parts of nitrobenzene as long as 180-185 C he heated until the dye formation is complete. A dye is obtained which dissolves orange-yellow in concentrated sulfuric acid and is separated from the sulfuric acid solution by water in golden-yellow flakes. It forms a dark purple güpe from which the fiber is colored in clear, golden yellow tones.

PATENTANSPRUCH: Verfahren zur Darstellung eines Küpen- farbstoffes der Anthrachinonreihe, dadurch gekennzeichnet, dass man 2 . 1- (S) -Anthra- chinonthioganthon-Bz2-karbonsäurechlorid von der Formel EMI0002.0007 mit 1- Amino - 5 - benzoylaminoatithrachinon durch Erhitzen in einem Lösungsmittel kon densiert. PATENT CLAIM: Process for the preparation of a vat dye of the anthraquinone series, characterized in that 2. 1- (S) -anthraquinone thioganthone-Bz2-carboxylic acid chloride of the formula EMI0002.0007 condensed with 1-amino-5-benzoylaminoatithraquinone by heating in a solvent. Der Farbstoff gibt mit konzentrierter Schwefelsäure eine orangegelbe Lösung, aus der er durch Wasser in goldgelben Flocken ausgeschieden wird und liefert eine dunkel violette Küpe, aus der die Faser in klaren, goldgelben Tönen gefärbt wird. With concentrated sulfuric acid, the dye gives an orange-yellow solution, from which it is excreted in golden-yellow flakes by water and provides a dark purple vat from which the fibers are dyed in clear, golden-yellow tones.
