  Verfahren zur Herstellung eines     Küpenfarbstoffes    der     Anthrachinonreihe.       Es wurde gefunden,     dal.',    man einen neuen       Küpenfarbstolf    der     Anthrachinonreihe    her  stellen kann, wenn     rnan    1     Mol.        1-Arnino-          6-chloranthrachinon    mit 1     111o1.        1:2-Naphto-          chinon-4-sulfosäure    kondensiert und auf die       0-Chinongruppe    des so erhaltenen Produktes  1     Mol.        2:

  3-Dianrinoanthrachinon    einwirken  lässt. Der so     gewonnene        Küpenfarbstoff    bildet  ein rotes Pulver, das sich in     Nitrobenzol     schwer mit roter, in     Oleum    und konzentrierter  Schwefelsäure mit grüner Farbe löst. Mit       Hydrosulfit    und Natronlauge wird eine rote       Küpe    erhalten, aus welcher Baumwolle in  satten, vorzüglich echten, blaustichig roten  Tönen gefärbt wird.    <I>Beispiel:</I>  15 Teile     1-Arrriiro-6-chloranthrachirron    wer  den in 750 Teilen Eisessig kochend gelöst  und hierauf auf 100  abgekühlt.

   Hierzu lässt  man eine heisse Lösung von 30 Teilen 1:2  Naphtoclrinon-4-sulfosaurern Kalium in 300  Teile     Wasser        fliehen    und kocht etwa     '/4    Stunde    am     R.ückfluss.    Man saugt     heil;    ab, wäscht  mit     heissem    Wasser neutral und trocknet.  



  10 Teile dieses Kondensationsproduktes  werden zusammen reit 7 Teilen ? :     3-Dianrino-          anthrachinon    und 500 Teilen     Nitrobenzol    auf  gekocht. Nach dein Abkühlen auf 100  wird  mit 20 Teilen     Eisessig    versetzt, eine Stunde  am     PlicliflulJkühler    weiter gekocht, warm fil  triert und der Rückstand, nachdem er mit  Alkohol und dann mit Wasser nachgewaschen  worden ist, getrocknet.



  Process for the production of a vat dye of the anthraquinone series. It was found that a new vat dye of the anthraquinone series can be produced if 1 mole of 1-amino-6-chloroanthraquinone is mixed with 11111. 1: 2-naphthoquinone-4-sulfonic acid condensed and 1 mol on the 0-quinone group of the product thus obtained. 2:

  3-Dianrinoanthraquinone can act. The vat dye obtained in this way forms a red powder that is difficult to dissolve in nitrobenzene with red, in oleum and concentrated sulfuric acid with a green color. With hydrosulfite and sodium hydroxide solution, a red vat is obtained, from which cotton is dyed in rich, exceptionally genuine, bluish red tones. <I> Example: </I> 15 parts of 1-arrriiro-6-chloranthrachirron are dissolved at the boil in 750 parts of glacial acetic acid and then cooled to 100.

   For this purpose, a hot solution of 30 parts of 1: 2 naphtoclrinone-4-sulfonic acid potassium in 300 parts of water is allowed to escape and refluxed for about 1/4 hour. One sucks safely; off, wash neutral with hot water and dry.



  10 parts of this condensation product are combined 7 parts? : 3-Dianrino-anthraquinone and 500 parts of nitrobenzene boiled. After cooling to 100, 20 parts of glacial acetic acid are added, the mixture is boiled for one hour on the Plicliflulkühler, filtered warm and the residue, after it has been washed with alcohol and then with water, dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines Küpen- farbstoffes der Anthrachinonreihe, dadurch ge kennzeichnet, da1@ man 1 Mol. 1-Amino-6- chloranthrachinon mit 1 141o1. 1:2-Naphto- chinon-4-sulfosäure kondensiert und auf die 0-Chinongruppe des so erhaltenen Produktes 1 IIol. 2:3-Diarninoanthrachiiiorr einwirken lässt. PATENT CLAIM: Process for the production of a vat dye of the anthraquinone series, characterized in that 1 mol. 1-amino-6-chloroanthraquinone with 1 141o1. 1: 2-naphthoquinone-4-sulfonic acid condensed and on the 0-quinone group of the product thus obtained 1 IIol. 2: 3-Diarninoanthrachiiiorr can act. Der so gewonnene Küpenfarbstoff bildet ein rotes Pulver, das sich in Nitrobenzol schwer mit roter, in Oleum und konzentrierter Schwefelsäure mit grüner Farbe löst. Mit Hydrosulfit und Natronlauge wird eine rote Küpe erhalten, aus welcher Baumwolle in satten; vorzüglich echten, blaustichig roten Tönen gefärbt wird. The vat dye obtained in this way forms a red powder that is difficult to dissolve in nitrobenzene with red, in oleum and concentrated sulfuric acid with a green color. With hydrosulphite and caustic soda a red vat is obtained, from which cotton in full; exquisitely real, bluish red tones.
