Description

  

      Zusatzpatent    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  
EMI0001.0007     
    mit     carbazolierenden        Mitteln    behandelt.  



  Das neue     Anthrachinonderivat    ist ein     K.ü-          penfarbstoff,    der sich in     konz.        Schwefelsäure     mit     violettbrauner    Farbe löst und pflanzliche       Fasern    aus     olivbrauner        güpe    in kräftigen       olivstichig        grünen    Tönen färbt.  



  Das als Ausgangsstoff für das vorliegende  Verfahren verwendete     Trianthrimid    kann bei  spielsweise aus     J.,4-Dihalogen-5-benzoylamino-          anthrachinonendurch    Umsetzung mit     \?        Mol          4-Aminoanthrachinon-2,1(N)        benzacridon    in       bekannter    Weise erhalten werden. Als     carbazo-          lierende    Mittel seien beispielsweise Alumi  niumchlorid und     Titantetrachlorid    genannt.  Diese     Mittel    können für     sich    allein oder in    Mischung bzw.

   Verbindung mit Salzen wie,       Natriumchlorid,    tertiären     aromatischen    Basen  wie     Pyridin    oder     Dimethylanilin,        Nitroben-          zolen,    Ammoniak,     .organischen        Nitrilen,    orga  nischen und     anorganischen    Säurechloriden und       Schwefeldioxyd    verwendet werden.

   Soweit  sich bei der     Behandlung        mit-carbazolierenden          Mittelnasserstoffreichere    Verbindungen     (Hy-          droverbindungen)    bilden,     ist    es     vorteilhaft,    die  erhaltenen Produkte     einer        oxydierenden    Be  handlung zu     unterwerfen,    was z. B. durch Be  handeln mit     Alkalihypochloritlösung,    mit Na  triumnitritlösung in -saurem     Medium:    oder     mil.          Perbaratlösung        geschehen    kann.

        <I>Beispiel:</I>  20 Teile     1,4-Dichlor-5-benzöylaminoanthra-          chinon,    36 Teile     4-Aminoanthrachinon-2,1(N)-          1',2'-(N)-benzacridon,    15 Teile Soda, 2     Teile          gupferchlorür    und 400 Teile Nitrobenzol wer  den 15     Stunden    zum Sieden erhitzt. Das Um  setzungsprodukt     wird    dann bei 50      abfiltriert,     mit     Nitrobenzol    gewaschen und durch Wasser  dampfdestillation von     Nitrobenzol    und' an  organischen Salzen befreit.

   Die neue     Verbin-          dung    löst     sieh    in     konz.    Schwefelsäure anfäng  lich mit brauner Farbe. Diese geht jedoch  rasch in ein Olive über. Beim     Austragen    die  ser     Schwefelsäurelösung    auf Wasser erhält  man olive Flocken.  



       In.    SO Gewichtsteile     Pyridin    werden bei 50  bis 100  langsam 40 Gewichtsteile     gemahlenes,            wasserfreies        Aluminiumchlorid    eingetragen.  Bei     etwa    100  trägt man nun in diese       Schmelze    20     Gewichtsteile    des     Trianthrimides     aus 1     -Mol        1,4-Dicblor-5-benzoylaminoanthra-          chinon        und:    2     Mo14-Aminoanthrachinon.-2,1(N)-          1.',2'(N)-benzacridtin    ein.

   Man     erhitzt    nun  11/2 Stunden zum Sieden und trägt dann die  Schmelze auf ein     Gemisch    von 300 Teilen Na  tronlauge von     36 \        B6    und 250 Teilen Wasser  aus. Nach dem     Abdestillieren    des     Pyridins     mit     Wässerdämpf    kann der neue     Farbstoff     durch     :Filtration    isoliert werden.



      Additional patent to main patent no. 250662. Process for the production of an anthraquinone derivative. It has been found that a valuable anthraquinone derivative can be made using the trianthrimide of the formula
EMI0001.0007
    treated with carbazolating agents.



  The new anthraquinone derivative is a Kü- pen dye, which is in conc. Sulfuric acid dissolves with a violet-brown color and dyes vegetable fibers from olive-brown güpe in strong olive-green tones.



  The trianthrimide used as starting material for the present process can be obtained, for example, from J., 4-dihalo-5-benzoylamino-anthraquinones by reaction with \? Mol of 4-aminoanthraquinone-2,1 (N) benzacridone can be obtained in a known manner. Examples of carbazolating agents are aluminum chloride and titanium tetrachloride. These agents can be used alone or in a mixture or

   Compounds with salts such as sodium chloride, tertiary aromatic bases such as pyridine or dimethylaniline, nitrobenzenes, ammonia, organic nitriles, organic and inorganic acid chlorides and sulfur dioxide can be used.

   Insofar as hydrogen-rich compounds (hydro compounds) are formed during the treatment with carbazolating agents, it is advantageous to subject the products obtained to an oxidizing treatment, B. act by Be with alkali hypochlorite solution, with sodium nitrite solution in acidic medium: or mil. Perbarate solution can happen.

        <I> Example: </I> 20 parts 1,4-dichloro-5-benzoylaminoanthraquinone, 36 parts 4-aminoanthraquinone-2,1 (N) - 1 ', 2' - (N) -benzacridone, 15 parts Soda, 2 parts gupferchlorür and 400 parts nitrobenzene who heated to boiling for 15 hours. The reaction product is then filtered off at 50, washed with nitrobenzene and freed from nitrobenzene and organic salts by steam distillation.

   The new connection loosens see in conc. Sulfuric acid initially brown in color. However, this quickly turns into an olive. When this sulfuric acid solution is poured onto water, olive flakes are obtained.



       In. 50 parts by weight of pyridine are slowly added 40 parts by weight of ground, anhydrous aluminum chloride at 50 to 100. At around 100, 20 parts by weight of the trianthrimide from 1 mol 1,4-dicbloro-5-benzoylaminoanthraquinone and: 2 Mo14-aminoanthraquinone-2,1 (N) - 1. ', 2' ( N) -benzacridtine.

   The mixture is now heated to boiling for 11/2 hours and then the melt is transferred to a mixture of 300 parts of sodium hydroxide solution of 36 \ B6 and 250 parts of water. After the pyridine has been distilled off with a water vapor, the new dye can be isolated by: Filtration.
