Description

  

      Zusatzpatent    zum Hauptpatent Nr.<B>156755.</B>    verfahren zur     Herstellung    eines     güpenfarbstoffes    der     Anthrachinonreihe.       Es wurde gefunden, dass man einen  neuen     Küpenfarbstoff    der     Anthrachinon-          reihe    erhält, wenn man auf 1     Mol        1,3-          Dihalogenanthrachinon    2     Mol        1,5-Monoben-          zoyldiaminoanthrachinon        einwirken    lässt.  



  Der neue Farbstoff stellt ein     rotbraunes     Pulver dar, das nach dem Umfällen aus kon  zentrierter Schwefelsäure Baumwolle aus der       Küpe    in kräftigen rotbraunen Tönen mit sehr  guten     Echtheiten    färbt.  



  <I>Beispiel:</I>  7,2     Teile        1,3-Dibrornanthrachinon,    14 Teile       1,5-Monobenzoyldiaminoanthrachinon,    8 Teile  wasserfreies     Natriumacetat    und 150 Teile       Nitrobenzol    werden sechs     Stunden    im Sie  den gehalten, wobei die entstehende Essig  säure     abdestilliert.    Man filtriert noch warm,  wäscht mit Nitrobenzol und Alkohol, kocht       dann    das     Reaktionsprodukt    mit Wasser aus,  filtriert und trocknet.  



       Zu    demselben Farbstoffe gelangt man,  wenn statt     1,3-Dibromanthrachinon    das 1,3-         Dichloranthrachinon    oder das     1-Chlor-3-brom-          anthrachinon    verwendet wird.  



  Ebenso wird dasselbe Resultat erhalten,  wenn das     Natriumacetat    durch     Kaliumacetat     oder     calcinierte        Alkalikarbonate    oder Mag  nesiumogyd ersetzt wird und wenn in Gegen  wart geeigneter Katalysatoren, wie Kupfer  oder Verbindungen des Kupfers, gearbeitet  wird.



      Additional patent to main patent no. <B> 156755. </B> Process for the production of a high quality dye of the anthraquinone series. It has been found that a new vat dye of the anthraquinone series is obtained if 2 moles of 1,5-monobenzoyldiaminoanthraquinone are allowed to act on 1 mole of 1,3-dihalogenanthraquinone.



  The new dye is a red-brown powder which, after reprecipitation from concentrated sulfuric acid, dyes cotton from the vat in strong red-brown shades with very good fastness properties.



  <I> Example: </I> 7.2 parts of 1,3-dibrornanthraquinone, 14 parts of 1,5-monobenzoyldiaminoanthraquinone, 8 parts of anhydrous sodium acetate and 150 parts of nitrobenzene are kept in the you for six hours, the acetic acid formed being distilled off. It is filtered while still warm, washed with nitrobenzene and alcohol, then the reaction product is boiled out with water, filtered and dried.



       The same dye is obtained if 1,3-dichloroanthraquinone or 1-chloro-3-bromoanthraquinone is used instead of 1,3-dibromoanthraquinone.



  The same result is also obtained if the sodium acetate is replaced by potassium acetate or calcined alkali metal carbonates or magnesium oxide and if suitable catalysts, such as copper or compounds of copper, are used in the presence.
