Description

  

      Zusatzpatent    zum Hauptpatent Nr. 156755.         Verfahren        zur        Herstellung    eines     Nüpenfarbstofes    der     Anthrachinonreihe.       Es     wurde    gefunden, dass man einen  neuen     Küpenfarbstoff    der     Anthrachinon-          reihe    erhält, wenn man auf 2     Mol        1-Acetyl-          amino-3-halogenanthrachinon    1     Mol.        1,5-Di-          aminoanthrachinon    einwirken lässt.  



  Der neue Farbstoff stellt ein blaurotes  Pulver dar, das sich in konzentrierter Schwe  felsäure mit rein blauer Farbe löst und  Baumwolle aus der     Küpe    in sehr echten  bordeauxroten Tönen färbt.  



  <I>Beispiel:</I>  1i,2 Teile     1-Acetylamino-3-brom-anthra-          chinon,    6 Teile     1,5-Diaminoanthrachinon,    8       'feile    wasserfreies     Natriumacetat,    1 Teil  Kupferacetat und 200 Teile Nitrobenzol wer  den 18 Stunden unter     Rückfluss    gekocht.  Man lässt etwas abkühlen und     filtriert    das  schön kristallisierte Umsetzungsprodukt ab.  



  Zum selben Farbstoffe gelangt man,  wenn statt     1-Acetylamino-3-bromanthrachi-          non    das     1-Acetylamino-3-ehloranthrachinon       verwendet wird.     Ebenso    wird dasselbe Re  sultat erhalten, wenn das     Natriumacetat     durch     Kaliumacetat    oder     caleinierte    Alkali  karbonate oder     Nagnesiumoxyd        und    das  Kupferacetat durch andere Kupferverbin  dungen oder metallisches Kupfer ersetzt  wird.



      Additional patent to main patent No. 156755. Process for the production of a nub dye of the anthraquinone series. It has been found that a new vat dye of the anthraquinone series is obtained if 1 mole of 1,5-di-aminoanthraquinone is allowed to act on 2 moles of 1-acetylamino-3-halogenanthraquinone.



  The new dye is a blue-red powder that dissolves in concentrated sulfuric acid with a pure blue color and dyes cotton from the vat in very real burgundy-red tones.



  <I> Example: </I> 1i, 2 parts 1-acetylamino-3-bromo-anthraquinone, 6 parts 1,5-diaminoanthraquinone, 8 'file anhydrous sodium acetate, 1 part copper acetate and 200 parts nitrobenzene are used for 18 hours refluxed. It is allowed to cool somewhat and the nicely crystallized reaction product is filtered off.



  The same dye is obtained if 1-acetylamino-3-ehloranthraquinone is used instead of 1-acetylamino-3-bromoanthraquinone. Likewise, the same result is obtained if the sodium acetate is replaced by potassium acetate or caleinated alkali carbonates or magnesium oxide and the copper acetate is replaced by other copper compounds or metallic copper.
