Description

  

  Zusatzpatent zum Hauptpatent Nr. 300336.    Verfahren     zur    Herstellung eines     Küpenfarbstoffes.       Es wurde gefunden, dass man zu einem wertvollen     Küpenfarbstoff    gelangt, wenn man  das     Anthrimid    der Formel  
EMI0001.0005     
    mit     carbazolierenden    Mitteln behandelt.  



  Der neue Farbstoff färbt Baumwolle aus  brauner     Küpe    in     grünoliven    Tönen.  



  Als     carbazolierende    Mittel kommen bei  spielsweise     Titantetrachlorid    und insbesondere  Aluminiumchlorid in Betracht. Die Reaktion  kann in an sich bekannter Weise in Gegenwart  passender     Lösungs-    bzw.     Verdünnungs-    oder       Flussmittel    durchgeführt werden, z.

   B. in Ge  genwart tertiärer Basen wie     Chinolin    oder  1'y     ridin,    von Nitrobenzol, mit Hilfe der be  kannten     Schwefeldioxyd-Aluminiumchlorid-          Additionsprodukte.    Als besonders zweckmässig       erweist    sich die     Carbazolierung    mit     Alumi-          niumchlorid-1Vatriumchlorid    oder mit Alumi  niumchlorid in technischen     ss,y-Picolingemisch.     Gute Ergebnisse werden in der Regel dann  erzielt, wenn man die     Carbazolierung    bei ver  hältnismässig hohen Temperaturen, z.

   B. bei  <B>1.60</B> bis 180 , ausführt, was mit den beiden  zuletzt erwähnten     Carbazolierungsmitteln    ohne  weiteres möglich ist.    <I>Beispiel:</I>  2,5 Teile     4,4'-Dibrom-1,1'-dianthrimid,     3,2 Teile     5'-Chlor-4-amino-1(N),2,2'(N),1'-          anthrachinonbenzolacridon,    0,8 Teile Natrium  acetat, 0,3 Teile     Kupfer(II)acetat    und 300  Teile Nitrobenzol werden 7     Stunden    zum  Sieden erhitzt. Nach dem Erkalten wird ab  gesaugt, mit Nitrobenzol, dann Alkohol aus  gewaschen und in üblicher Weise gereinigt.  Man erhält das     Anthrimid    in Form eines  dunkel gefärbten Pulvers.  



  1 Teil desselben wird in einer Schmelze  von 30 Teilen Aluminiumchlorid und 6 Teilen       Natriumchlorid    1 Stunde auf 160 bis 1650 er  hitzt. Man giesst sodann auf Eis aus und fil  triert. Der Rückstand wird ausgewaschen und  in stark verdünnter Schwefelsäure suspen  diert. Nach Zusatz von 0,3 Teilen     Natrium-          bichromat    lässt man 5 bis 6 Stunden bei Zim  mertemperatur rühren, filtriert hierauf wie  der und wäscht gründlich mit Wasser aus.  Der so erhaltene Farbstoff kann in     Pulver-          oder        Pastenform    zur Verwendung gelangen.



  Additional patent to main patent no. 300336. Process for the production of a vat dye. It has been found that a valuable vat dye is obtained by using the anthrimide of the formula
EMI0001.0005
    treated with carbazolating agents.



  The new dye dyes cotton from a brown vat in green-olive tones.



  Suitable carbazolating agents are, for example, titanium tetrachloride and, in particular, aluminum chloride. The reaction can be carried out in a manner known per se in the presence of suitable solvents, diluents or fluxes, eg.

   B. in Ge present tertiary bases such as quinoline or 1'y ridin, from nitrobenzene, with the help of the known sulfur dioxide-aluminum chloride addition products. Carbazolation with aluminum chloride-1-sodium chloride or with aluminum chloride in a technical γ-picolin mixture has proven to be particularly useful. Good results are usually achieved if the carbazolation is carried out at relatively high temperatures, e.g.

   B. at <B> 1.60 </B> to 180, which is easily possible with the two last-mentioned carbazolating agents. <I> Example: </I> 2.5 parts 4,4'-dibromo-1,1'-dianthrimide, 3.2 parts 5'-chloro-4-amino-1 (N), 2.2 '( N), 1'-anthraquinone benzene acridone, 0.8 part of sodium acetate, 0.3 part of copper (II) acetate and 300 parts of nitrobenzene are heated to the boil for 7 hours. After cooling, it is filtered off with suction, washed off with nitrobenzene and then with alcohol and cleaned in the usual way. The anthrimide is obtained in the form of a dark-colored powder.



  1 part of the same is heated in a melt of 30 parts of aluminum chloride and 6 parts of sodium chloride for 1 hour to 160 to 1650. It is then poured onto ice and filtered. The residue is washed out and suspended in very dilute sulfuric acid. After adding 0.3 part of sodium bichromate, the mixture is stirred for 5 to 6 hours at room temperature, then filtered again and washed thoroughly with water. The dye thus obtained can be used in powder or paste form.
