Description

  

      Zusatzpatent    zum Hauptpatent Nr. 243843.         Verfahren        zur        Herstellung        eines        Küpenfarbstoffes.       Es wurde gefunden, dass ein wertvoller       Küpenfarbstoff    hergestellt werden kann,  wenn man 1     Mo.l        1,5-Diaminoanthrachinon-          2,6-dicarbonsäure    oder eines ihrer funktionel  len Derivate mit 2     Mol        1-Amino-4-phenyl-          aminoanthrachinon    umsetzt.  



  Der neue Farbstoff ist ein dunkles Pulver,  das sich in     konz.    Schwefelsäure mit grüner  Farbe löst und Baumwolle aus schwarz  brauner     Küpe    in blaustichig     violetten    Tönen  färbt.  



  Zur Durchführung der Umsetzung kann  die     genannte        Dicarbonsäure    oder vorzugs  weise eines ihrer     funktionellen    Derivate, bei  spielsweise ein     Säurehalogenid    und insbeson  dere das Säurechlorid verwendet werden. Die       Reaktion    wird zweckmässig in einem indiffe  renten     Lösungs-        bezw.        Verteilungsmittel    vor  genommen, wobei insbesondere solche von  höherem Siedepunkt, wie Chlorbenzol,     Nitro-          benzol    oder     Dichlorbenzol,    in Betracht kom  men.

   Man kann die Umsetzung     beispiels-          weise    bei erhöhter Temperatur,     in    An- oder  Abwesenheit säurebindender Mittel durch  führen.  



       Beispiel:     Zu der Lösung von 15,7 Teilen     1-Amino-          4-phenylaminoanthrachinon    in 500 Teilen  trockenem     Nitrobenzol    gibt man bei 90 bis       l.00     9,1 Teile     1,5-Diaminoanthrachinon-2,6-          dicarbonsäurechlorid.    Hierauf steigert man  die Temperatur innert     x/2    Stunde auf l.50 .

    Zur Beendigung der     Farbstoffbildung    rührt    man noch 2     Stunden    bei 150-160 , filtriert  dann in der Wärme ab, wäscht     mit        Nitro-          benzol    und Alkohol     aus    und trocknet.  



  Das in diesem Beispiel verwendete Säure  chlorid kann wie folgt erhalten werden:  5     Teile        1,5-Diaminoanthrachinon-2,6-di-          carbonsäure    werden mit 60     Teilen    trockenem  Nitrobenzol vermahlen. Zu der feinen Sus  pension gibt man nun weitere 540 Teile  trockenes Nitrobenzol, 1 Teil     Pyridin    und 17  Teile     Thionylchlorid    hinzu und erhitzt das  Gemisch     während        1/.1    Stunde auf 90-100 .  Dabei geht die     1,5-Diaminoanthrachinon-2,6-          dicarbonsäure    in Lösung.

   Man filtriert von  einigen     Verunreinigungen    ab und lässt das  Filtrat erkalten. Das     1,5-Diaminoanthrachi-          non-2,6-dicarbonsäurechlorid    kristallisiert in  grünlich schillernden, rotbraunen Nadeln     aus.     Es wird abgesaugt, mit Aceton und Wasser  (zur     Entfernung    von salzsaurem     Pyridin)    ge  waschen und im     Egsiccator    getrocknet.



      Additional patent to the main patent No. 243843. Process for the production of a vat dye. It has been found that a valuable vat dye can be produced if 1 mol of 1,5-diaminoanthraquinone-2,6-dicarboxylic acid or one of its functional derivatives is reacted with 2 mol of 1-amino-4-phenylaminoanthraquinone.



  The new dye is a dark powder that is in conc. Sulfuric acid dissolves with a green color and dyes cotton from a black-brown vat in bluish violet tones.



  The dicarboxylic acid mentioned or preferably one of its functional derivatives, for example an acid halide and in particular the acid chloride, can be used to carry out the reaction. The reaction is expediently in an indifferent solution or. Distribution agents taken before, in particular those with a higher boiling point, such as chlorobenzene, nitrobenzene or dichlorobenzene, are suitable.

   The reaction can be carried out, for example, at elevated temperature, in the presence or absence of acid-binding agents.



       Example: 9.1 parts of 1,5-diaminoanthraquinone-2,6-dicarboxylic acid chloride are added to the solution of 15.7 parts of 1-amino-4-phenylaminoanthraquinone in 500 parts of dry nitrobenzene at 90 to 1.00. The temperature is then increased to 1.50 within x / 2 hours.

    To complete the formation of the dye, the mixture is stirred for a further 2 hours at 150-160, then filtered off in the heat, washed with nitrobenzene and alcohol and dried.



  The acid chloride used in this example can be obtained as follows: 5 parts of 1,5-diaminoanthraquinone-2,6-dicarboxylic acid are ground with 60 parts of dry nitrobenzene. A further 540 parts of dry nitrobenzene, 1 part of pyridine and 17 parts of thionyl chloride are then added to the fine suspension and the mixture is heated to 90-100 for 1/1 hour. The 1,5-diaminoanthraquinone-2,6-dicarboxylic acid goes into solution.

   Some impurities are filtered off and the filtrate is allowed to cool. The 1,5-diaminoanthraquinone-2,6-dicarboxylic acid chloride crystallizes out in greenish shimmering, red-brown needles. It is filtered off with suction, washed with acetone and water (to remove hydrochloric acid pyridine) and dried in an Egsiccator.
