  Verfahren zur Herstellung eines     liüpenfarbstoffes    der     Anthrachinonreihe.       Es wurde gefunden, dass man einen neuen       l#'-üpenfarbstoff    der     Anthrachinonreihe    her  stellen kann, wenn man 1     Mol.        1-Aminoan-          thrachinon    mit 1     Mol.        6-Brom-1:2-naphtochi-          non        kondensiert    und auf die     o-Chino.ngruppe     des so erhaltenen Produktes 1     Mol.        2:

  3-D1a-          minoanthrachinon    einwirken lässt. Der so ge  wonnene     Küpenfarbstoff    bildet ein rotes Pul  ver, das sich in Nitrobenzol schwer mit roter,  in     Oleum    und konzentrierter Schwefelsäure  mit olivgrüner Farbe löst. Mit     Hydrosulfit     und Natronlauge wird eine braune     güpe    er  halten, .aus welcher Baumwolle in satten, vor  züglich echten roten Tönen gefärbt     wird.     



  <I>Beispiel:</I>  18 Teile     6-Brom-l:2-naphtochinon        werden     zusammen mit 15 Teilen     1-Aminoanthrachi-          non,    9 Teilen     entwässertem        Natriumacetat,     0,4 Teilen Kupferchlorid in 1000 Teilen Eis  essig 1 Stunde unter     Rückfluss    gekocht. Nach  dem Erkalten wird abgesaugt, der     Rückstand     mit heissem Wasser neutral gewaschen und  getrocknet.  



  10 Teile dieses Kondensationsproduktes  werden zusammen mit 7 Teilen     2:3-Diamino-.            authrachinon    und 850 Teilen     Nitrobenzol    auf  gekocht. Nach dem Abkühlen auf<B>100'</B> wird  mit 20 Teilen Eisessig versetzt, eine Stunde  am     Rückflusskühler    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 liup dye of the anthraquinone series. It has been found that a new l # '- over dye of the anthraquinone series can be produced by condensing 1 mole of 1-aminoanthrachinone with 1 mole of 6-bromo-1: 2-naphthoquinone and condensing it onto the o- Chino.ngruppe of the product thus obtained 1 mol. 2:

  3-D1aminoanthraquinone 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 an olive green color. With hydrosulphite and caustic soda, a brown color is obtained, from which cotton is dyed in rich red tones that are really attractive.



  <I> Example: </I> 18 parts of 6-bromo-1: 2-naphthoquinone are refluxed for 1 hour together with 15 parts of 1-aminoanthraquinone, 9 parts of dehydrated sodium acetate, 0.4 part of copper chloride in 1000 parts of glacial acetic acid cooked. After cooling, it is filtered off with suction, the residue is washed neutral with hot water and dried.



  10 parts of this condensation product are together with 7 parts of 2: 3-diamino-. authrachinon and 850 parts of nitrobenzene on boiled. After cooling to <B> 100 '</B>, 20 parts of glacial acetic acid are added, the mixture is boiled for one hour on the reflux condenser, filtered warm and the residue, after it has been washed with alcohol and then with water, is dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines Küpen- farbstoffes der Anthrachinonreihe, dadurch gekennzeichnet, dass man 1 Mol. 1-Amino- anthrachinon mit 1 Mol. 6-1:2-naphtachinon kondensiert und auf die o-Cliinongruppe des so erhaltenen Produktes 1 Mol: 2:3-Diamino- anthrachinon einwirken lässt. PATENT CLAIM: Process for the production of a vat dye of the anthraquinone series, characterized in that 1 mole of 1-amino anthraquinone is condensed with 1 mole of 6-1: 2-naphthaquinone and 1 mole of the product obtained in this way is applied to the o-cliinone group: 2: 3-diamino anthraquinone can act. Der so gewon nene Küpenfarbstoff bildet ein rotes Pulver, das sich in Nitrobenzol schwer mit roter, in Oleum und konzentrierter Schwefelsäure mit olivgrüner Farbe löst. Mit Hydrosulfit und Natronlauge wird eine braunrote Küpe er halten, aus welcher Baumwolle in satten, vor züglich echten roten Tönen gefärbt wird. The vat dye obtained in this way forms a red powder, which is difficult to dissolve in nitrobenzene with red, in oleum and concentrated sulfuric acid with an olive-green color. With hydrosulphite and caustic soda, a brown-red vat is obtained from which cotton is dyed in rich red tones that are really attractive.
