  <B>Zusatzpatent</B> zum Hauptpatent Nr. 250662.    Verfahren zur Herstellung eines     Anthrachinonderivates.       Es wurde gefunden,     @dass    ein wertvolles       Anthrachinonderivat    hergestellt werden kann.  wenn man das     Trianthrimid    der Formel  
EMI0001.0005     
    mit     carbazolierenden        Mitteln    behandelt.    Das neue     Anthrachinonderivat    ist ein     Kü-          penfarbstoff,    der pflanzliche Fasern aus brau  ner     Küpe    in echten braunen Tönen färbt.  



  Das als Ausgangsstoff für das vorliegende  Verfahren     verwendete        Trianthrimid    kann bei  spielsweise aus     1,4-Dihalogen-5-nikotinoyl-          aminoanthrachinonen    durch Umsetzung mit  2     Mol        1-Aminoanthrachinon    in bekannter  Weise erhalten werden. Als     carbazolierende     Mittel seien     beispielsweise    Aluminiumchlorid       r.nd        Titantetrachlorid    genannt. Diese Mittel  können für sich allein oder in Mischung bzw.

    Verbindung mit Salzen wie     Natriumchlorid,     tertiären aromatischen Basen wie     Pyridin    oder       Dimethylanilin,        Nitrobenzolen,    Ammoniak;    organischen     Nitrilen,    organischen und an  organischen Säurechloriden und Schwefel  dioxyd verwendet werden. Soweit sich bei der  Behandlung mit     carbazolierenden        Mitteln     wasserstoffreichere     Verbindungen:        (Hydrover-          bindungen)    bilden, ist es vorteilhaft, die er  haltenen Produkte einer oxydierenden Be  handlung zu unterwerfen, was z.

   B. durch  Behandeln mit     Alkalihypochloritlösung,        mit          Natriumnitritlösung    in saurem Medium oder  mit     Perboratlösung    geschehen     kann.       <I>Beispiel:

  </I>    <B>19,8</B> Teile des Reaktionsproduktes. aus je  1     Mol        1,4-Dichlor-5-aminoanthrachinon    und       Nikotinsäurechlorid-Chlörhydrat    (grüngelbes  Kristallpulver vom     Smp.    148 bis 152 ),  25 Teile     1-Aminoanthrachinon,    15 Teile Na  triumcarbonat, 1 Teil     Kupferchlorür        @    und  200 Teile Naphthalin werden 15     Stunden    zum       Sieden    erhitzt. Die     Reaktionsmasse    wird dann  bei etwa 180  mit 400 Teilen Chlorbenzol ver  dünnt.

   Das kristallisierte Reaktionsprodukt  wird nun bei 50 bis 55      abfiltriert,    mit Chlor  benzol gewaschen, der     Presskuchen    der Was  serdampf     destillation-        unterworfen    und die neue  Verbindung durch Filtration isoliert. Sie löst  sich in     konzentrierter    Schwefelsäure mit gras  grüner Farbe.  



  In 80     Gewichtsteile        Pyridin    werden bei  50 bis 100  langsam 40     Gewichtsteile    gemah  lenes, wasserfreies Aluminiumchlorid einge-    tragen. Bei     etwa        100     trägt man nun in diese      Schmelze 20     Gewichtsteile        des        Trianthrimides     aus 1     Mol        1,

  4-Dichlor-5-nikotinoylamino-          anthracbinon    und 2     Mol        1-Aminoanthraohinon          ein.    Man erhitzt nun eine Stunde zum Sie  den und trägt     dann    die Schmelze auf ver  dünnte Natronlauge aus. Nach dem Abdestil-    Tieren .des     Pyridins    kann der neue     Farbstoff     durch Filtration isoliert werden.



  <B> Additional patent </B> to main patent no. 250662. Process for the production of an anthraquinone derivative. It was found @that a valuable anthraquinone derivative can be produced. if you take the trianthrimide of the formula
EMI0001.0005
    treated with carbazolating agents. The new anthraquinone derivative is a vat dye that dyes vegetable fibers from a brown vat in real brown tones.



  The trianthrimide used as starting material for the present process can be obtained in a known manner, for example, from 1,4-dihalo-5-nicotinoyl-aminoanthraquinones by reaction with 2 moles of 1-aminoanthraquinone. Examples of carbazolating agents are aluminum chloride and titanium tetrachloride. These agents can be used alone or in a mixture or

    Compound with salts such as sodium chloride, tertiary aromatic bases such as pyridine or dimethylaniline, nitrobenzenes, ammonia; organic nitriles, organic and organic acid chlorides and sulfur dioxide are used. Insofar as hydrogen-rich compounds are formed during treatment with carbazolating agents (hydro-compounds), it is advantageous to subject the products he received to an oxidizing treatment, which z.

   B. can be done by treating with alkali hypochlorite solution, with sodium nitrite solution in an acidic medium or with perborate solution. <I> example:

  </I> <B> 19.8 </B> parts of the reaction product. from 1 mole of 1,4-dichloro-5-aminoanthraquinone and nicotinic acid chloride chlorohydrate (green-yellow crystal powder with a melting point of 148 to 152), 25 parts of 1-aminoanthraquinone, 15 parts of sodium carbonate, 1 part of copper chloride and 200 parts of naphthalene are 15 hours heated to boiling. The reaction mass is then diluted ver at about 180 with 400 parts of chlorobenzene.

   The crystallized reaction product is then filtered off at 50 to 55, washed with chlorobenzene, the press cake of what is subjected to steam distillation and the new compound is isolated by filtration. It dissolves in concentrated sulfuric acid with a grass-green color.



  In 80 parts by weight of pyridine, 40 parts by weight of ground, anhydrous aluminum chloride are slowly entered at 50 to 100. At around 100, 20 parts by weight of the trianthrimide from 1 mol of 1 are added to this melt,

  4-dichloro-5-nicotinoylamino-anthracbinone and 2 moles of 1-aminoanthraohinone. It is now heated for an hour and then the melt is applied to dilute sodium hydroxide solution. After the pyridine has been distilled off, the new dye can be isolated by filtration.
