Description

  

  Verfahren zur Herstellung eines     Küpenfarbstoffes.       Es wurde gefunden, dass man einen wert  vollen     Küpenfarbstoff    erhält, wenn man den  durch     Umsetzen    von     6,Bz1-Dibrombenz-          anthron    zunächst mit 1     Mol        1-Aminoanthra-          cUinon    und dann mit 1     Mol        1-Amino-2-cyan-          anthrachinon    erhältlichen Stoff mit alka  lischen     Kondensationsmitteln    behandelt.  



  Der neue Farbstoff färbt Baumwolle aus  ,der     Küpe    in     braunstichig    oliven, gut egali  sierten, chlor- und     sodakochechten    Tönen.  



  Die in folgendem Beispiel genannten Teile  sind Gewichtsteile.  



  <I>Beispiel:</I>  Ein Gemisch aus 50 Teilen     6,Bzl-Di-          bro-mbenzanthron,    28,<B>8</B> Teilen 1 -     Amino-          anthrachinon,    19,3 Teilen     wasserfreiem        Na-          triumcarbonat,    1,9 Teilen fein verteiltem  Kupferoxyd und 480 Teilen Nitrobenzol wird       unter    Rühren mehrere Stunden zum Sieden  erhitzt.

   Dann lässt man auf     170-180 '    ab  kühlen,     trägt    32,1 Teile     1-Amino-2-cyan-          anthrachinon,   <B>1.9,3</B> Teile wasserfreies Na-         triumcarbonat    und 1,9 Teile Kupferoxyd ein  und erhitzt hierauf das     Ganze        etwa    15 Stun  den zum Sieden.

   Nach dem     Abkühlen    auf 80  bis 90  saugt man das     ausgeschiedene        Imid     ab, befreit es in üblicher Weise von anhaften  dem     Lösungsmittel        und    anorganischen     Bei-          mengungen    und trocknet es.  



  100 Teile dieses     Imids    trägt man     unter     Rühren     in,eine    etwa 100-105  heisse Schmelze  von 400     Teilen        Kaliumhydroxyd    und 400 Tei  len     Äthanof@ein    und rührt     date        Gemisch    5 Stun  den bei dieser     Temperatur    weiter. Dann giesst  man     in    Wasser kocht     unter    Einleiten von Luft  bis der Farbstoff sich     ausgeschieden    hat, saugt  ihn ab, wäscht mit Wasser aus und trocknet.

    Man erhält so -einen Farbstoff, ,der Baum  wolle aus der alkalischen     Hydrosulfitküpe    in       braunstichig    oliven Tönen färbt. Das     Egali-          eiervermögen,    die Chlor- und     So:dakochecht-          heit    des neuen Farbstoffes ist besser als .die  des     entsprechenden    Farbstoffes aus     6,Bzl-          Di-(1''-anthra@chinonyl)-amino-benzanthron.  



  Process for the production of a vat dye. It has been found that a valuable vat dye is obtained if the substance obtainable by reacting 6, Bz1-dibromobenzanthrone first with 1 mole of 1-aminoanthracuinone and then with 1 mole of 1-amino-2-cyanoanthraquinone treated with alkaline condensation agents.



  The new dye dyes cotton, the vat in brownish olive, well-leveled, chlorine- and soda-proof shades.



  The parts mentioned in the following example are parts by weight.



  <I> Example: </I> A mixture of 50 parts of 6, Bzl-dibro-mbenzanthron, 28, <B> 8 </B> parts of 1 - amino anthraquinone, 19.3 parts of anhydrous sodium carbonate, 1.9 parts of finely divided copper oxide and 480 parts of nitrobenzene are heated to boiling for several hours while stirring.

   The mixture is then allowed to cool to 170-180 ', 32.1 parts of 1-amino-2-cyano-anthraquinone, 1.9.3 parts of anhydrous sodium carbonate and 1.9 parts of copper oxide are introduced and the mixture is heated then boil for about 15 hours.

   After cooling to 80 to 90, the precipitated imide is filtered off with suction, freed from adhering solvent and inorganic additions in the usual way and dried.



  100 parts of this imide are introduced into an approximately 100-105 hot melt of 400 parts of potassium hydroxide and 400 parts of ethane, with stirring, and the mixture is stirred for 5 hours at this temperature. Then it is poured into water and boiled while air is passed in until the dye has separated out, sucks it off, washed out with water and dried.

    This gives a dye, the cotton dyes from the alkaline hydrosulfite vat in brownish olive tones. The leveling capacity, the chlorine and So: dakochfastness of the new dye is better than that of the corresponding dye from 6, Bzl-di- (1 "- anthra @ quinonyl) -amino-benzanthrone.
