      Zusatzpatent        zum    Hauptpatent Nr. 250662.         Verfahren    zur Herstellung eines     Anthraehinonderivates.       Es wurde gefunden, dass ein wertvolles     Anthrachinonderivat        hergestellt    werden kann.  wenn man das     Trianthrimid    der Formel  
EMI0001.0008     
    mit     carbazolierenden    Mitteln behandelt.  



  Das neue     Anthrachinonderivat    ist ein     Kii-          penfarbstoff,    der pflanzliche     Fasern    aus brau  ner     Küpe    in echten     rotstichig    braunen Tönen  färbt.  



  Das als Ausgangsstoff für das vorliegende  Verfahren verwendete     Trianthrimid    kann  beispielsweise     aus        1.4-Dihalogen-5-benz.oyl-          aminoanthrachinonen    durch Umsetzung mit  2     Mol        1-Amino-5-benzoylaminoanthrachinon     in bekannter Weise erhalten werden, Als       carbazolierend-e    Mittel seien beispielsweise  Aluminiumchlorid und     Titantetrachlorid    ge  nannt.

   Diese Mittel können für sich     allein     oder in     Mischung        bzw.    Verbindung mit Sal  zen wie     Natriumchlorid,    tertiären aromati-    sehen Basen wie     Pyridin    oder     Dimethylanilin,     Nitrobenzolen, Ammoniak, organischen Ni  trilen,     organischen    und anorganischen Säure  chloriden und     Schwefeldioxyd    verwendet wer  den.

   Soweit sich bei der     Behandlung    mit       carbazolierenden        Mitteln    wasserstoffreichere  Verbindungen     (Hydroverbindungen)    bilden,  ist es vorteilhaft, die erhaltenen Produkte       einer    oxydierenden Behandlung zu unterwer  fen, was z. B. durch Behandeln     mit    Alkali  hypochloritlösung, mit     Natriumnitritlösung-    in  saurem Medium oder mit     Perboratlösung    ge  schehen kann.  



  <I>Beispiel:</I>  19,8     Gewichtsteile        1-Benzoylamino-5.8-          dichloranthracIiinon,    38     Gewichtsteile        1-Amino-          5-benzoylaminoanthrachinon,    15     Gewichtsteile              Nätritunearbonat,    1     Gewichtsteil        Kupfer-          chlorür    und 300     Gewichtsteile    Naphthalin  werden     zusammen    -15 Stunden zum Sieden  des Naphthalins erhitzt. Man kühlt nachher  auf etwa l30  ab und gibt 600 Gewichtsteile  Chlorbenzol zu.

   Das schön kristallisierte Re  aktionsprodukt wird nun bei 50 bis 55  ab  filtriert, mit Chlorbenzol gewaschen, der       Presskuchen    der     Wasserdampfdestillation    un  terworfen und .die neue Verbindung durch Fil  tration     isoliert.    Sie löst     eich    in     konzentrierter     Schwefelsäure mit .olivgrüner 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-benzoyiaminoanthra-          chinon    und 2     Mol        1-Amino-5-benzoylamino-          authrachinon    ein.

   Man erhitzt nun eine     Stunde     zum     Sieden    und trägt dann die Schmelze auf  verdünnte Natronlauge aus. Nach dem Ab  destillieren des     Pyridins    kann der neue     Farb-          stoff    durch     Filtration    isoliert werden.



      Additional patent to main patent no. 250662. Process for the production of an anthraehinone derivative. It has been found that a valuable anthraquinone derivative can be produced. if you take the trianthrimide of the formula
EMI0001.0008
    treated with carbazolating agents.



  The new anthraquinone derivative is a pot dye that dyes vegetable fibers from a brown pot in real reddish brown tones.



  The trianthrimide used as the starting material for the present process can be obtained in a known manner, for example, from 1,4-dihalo-5-benz.oyl-aminoanthraquinones by reaction with 2 moles of 1-amino-5-benzoylaminoanthraquinone. Examples of carbazolating agents are aluminum chloride and Called titanium tetrachloride.

   These agents can be used alone or in admixture with salts such as sodium chloride, tertiary aromatic bases such as pyridine or dimethylaniline, nitrobenzenes, ammonia, organic Ni triles, organic and inorganic acid chlorides and sulfur dioxide.

   As far as hydrogen-rich compounds (hydro compounds) form during the treatment with carbazolating agents, it is advantageous to subject the products obtained to an oxidizing treatment, which z. B. by treating with alkali hypochlorite solution, with sodium nitrite solution in an acidic medium or with perborate solution ge can happen.



  <I> Example: </I> 19.8 parts by weight of 1-benzoylamino-5.8-dichloroanthracinone, 38 parts by weight of 1-amino-5-benzoylaminoanthraquinone, 15 parts by weight of natritune carbonate, 1 part by weight of copper chloride and 300 parts by weight of naphthalene are combined for -15 hours Boiling the naphthalene heated. It is then cooled to about 130 and 600 parts by weight of chlorobenzene are added.

   The nicely crystallized reaction product is then filtered off at 50 to 55, washed with chlorobenzene, the presscake is subjected to steam distillation and the new compound is isolated by filtration. It dissolves in concentrated sulfuric acid with an olive green color.



  In 80 parts by weight of pyridine, 40 parts by weight of ground, anhydrous aluminum chloride are slowly added at 50 to 100. At about 100, 20 parts by weight of the trianthrimide from 1 mole of 1,4-dichloro-5-benzoyiaminoanthraquinone and 2 moles of 1-amino-5-benzoylamino-authraquinone are now introduced into this melt.

   The mixture is then heated to boiling for an hour and then the melt is poured onto dilute sodium hydroxide solution. After the pyridine has been distilled off, the new dye can be isolated by filtration.
