      Znsatzpaf;ent    zum Hauptpatent Nr. 93280.    Verfahren zur Herstellung eines     Iiüpenfarbstoffes    der     Anthrachinonreihe.       Es wurde gefunden, dass man einen neuen       Küpenfarbstoff    der     Anthrachinonreihe    her  stellen kann, wenn man 1 Molekül 2 :     3-Di-          aminoanthraehinon    mit 1 Molekül     6-Brom-          1        :2-naphtochinon    kondensiert und auf das  so erhaltene Produkt 1 Molekül     1-Aminoan-          thrachinon    einwirken lässt.

   Der so gewonnene       Küpenfarbstoff    bildet ein braunrotes Pulver,  das sich in     Nitrobenzol    schwer mit roter, in  konzentrierter Schwefelsäure mit brauner  Farbe löst. Mit     Hydrosulfit    und Natronlauge  wird eine braune     Küpe    erhalten, aus welcher  Baumwolle in satten, vorzüglich echten rot  braunen Tönen gefärbt wird.  



  <I>Beispiel:</I>  18 Teile     6-Brom-1        :2-naphtochinon    und  15 Teile     2.3-Diaminoanthrachinon    werden  in 180 Teile Eisessig eingetragen, hierauf  unter stetem Rühren langsam auf 90 bis 100    erhitzt.     Man    rührt weiter bei dieser Tempe  ratur, bis die Reaktion     stattgefunden    hat, lässt  dann erkalten, filtriert, wäscht den Rückstand  reichlich mit heissem Wasser und trocknet.    Das so erhaltene Produkt bildet ein grün  gelbes Pulver, das sieh mit blauvioletter  Farbe in konzentrierter Schwefelsäure löst.  



  9 Teile dieses Produktes werden nun zu  sammen     zeit    6 Teilen     1-Aminoanthra:chinon,     6 Teilen entwässertem     Natriumacetat,        1ss    Teil  entwässertem     Cuprichlorid    und 300 Teilen       Nitrobenzol    16 Stunden am     Rückflusskühler     gekocht.     Naoh    dem Erkalten wird abgesaugt,  der Rückstand nacheinander mit Alkohol, ver  dünnter Salzsäure und heissem Wasser gewa  schen und     getrocknet.  



      Znsatzpaf; ent to the main patent No. 93280. Process for the production of a liquid dye of the anthraquinone series. It has been found that a new vat dye of the anthraquinone series can be produced if 1 molecule of 2: 3-di-aminoanthraehinone is condensed with 1 molecule of 6-bromo-1: 2-naphthoquinone and 1 molecule of 1-aminoane is condensed onto the product thus obtained - lets thrachinon take effect.

   The vat dye obtained in this way forms a brownish-red powder that is difficult to dissolve in nitrobenzene with red, in concentrated sulfuric acid with brown color. With hydrosulfite and caustic soda, a brown vat is obtained, from which cotton is dyed in rich, exquisitely genuine red-brown tones.



  <I> Example: </I> 18 parts of 6-bromo-1: 2-naphthoquinone and 15 parts of 2,3-diaminoanthraquinone are introduced into 180 parts of glacial acetic acid, then slowly heated to 90 to 100 with constant stirring. The mixture is stirred at this temperature until the reaction has taken place, then allowed to cool, filtered, the residue is washed copiously with hot water and dried. The product obtained in this way forms a green-yellow powder, which dissolves in concentrated sulfuric acid with a blue-violet color.



  9 parts of this product are now 6 parts of 1-aminoanthra: quinone, 6 parts of dehydrated sodium acetate, 1ss part of dehydrated cupric chloride and 300 parts of nitrobenzene are refluxed for 16 hours. After cooling, the residue is filtered off with suction, washed successively with alcohol, dilute hydrochloric acid and hot water and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines Küpen- faTbstoffes der Anthrachinonreihe, dadurch gekennzeichnet, dass man 1 Molekül 2 : 3- Diaminoanthrachinon mit 1 Molekül 6-Brom- 1 : 2-n.aphtochinon kondensiert und auf das so erhaltene Produkt 1 Molekül 1-Amino-an- thrachinon einwirken lässt. PATENT CLAIM: Process for producing a vat dye of the anthraquinone series, characterized in that 1 molecule of 2: 3-diaminoanthraquinone is condensed with 1 molecule of 6-bromo-1: 2-n.aphthoquinone and 1 molecule of 1-amino is condensed onto the product thus obtained -anthrachinon can act. Der so gewonnene güpenfarbstoff bildet ein braunrotes Pulver, das sich in Nitrobenzol schwer mit roter, in konzentrierter ,Schwefelsäure mit brauner Farbe löst. Mit Hydrosulfit und Natronlauge wird eine braune güpe erhalten, aus welcher Baumwolle in satten, vorzüglich echten rot braunen Tönen gefärbt wird. The pigment obtained in this way forms a brownish-red powder that is difficult to dissolve in nitrobenzene with red, in concentrated sulfuric acid with a brown color. With hydrosulfite and caustic soda a brown güpe is obtained, from which cotton is dyed in rich, exquisitely real red-brown tones.
