  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 156755.    Verfahren zur Herstellung eines     Küpenfarbstoffes    der     Antliraehinonreihe.       Es wurde gefunden, dass man einen neuen       Küpenfarbstoff    der     Anthrachinonreihe    erhält,  wenn man auf 1     Mol        1-Benzoylamino-3-          halogenanthrachinon    1     Mol        4-Amino-4'-chlor-          2,1-        anthrachinonthioxanthon    einwirken lässt.  



  Der neue     Farbstoff    stellt ein dunkles  Pulver dar, das nach dem Umfällen aus       konzentrierter    Schwefelsäure Baumwolle aus  der     Küpe    in kräftigen grauen Tönen von  sehr guter Echtheit färbt.  



       Beispiel.:     10     '.feile    1     -Benzoylamino-3-bromanthra-          chinon,    10 Teile     4-Amino-4'-chloi--2,1-anthra-          chinonthioxanthon,    5 Teile wasserfreies Na  triumacetat, 1 Teil Kupferacetat und 400  Teile Nitrobenzol werden 20 Stunden am       Rückflusskühler    gekocht. Das Reaktionspro  dukt wird noch warm     abfiltriert,        finit        Nitro-          benzol,    Alkohol und schliesslich mit heissem  Wasser gewaschen.  



  Zu demselben     Farbstoff    gelangt man,  wenn statt 1-Ber)zuylamino.3-bromanthrachi-         non    das     1-Berizoylamino-3-chloranthrachinon     verwendet wird. Ebenso wird dasselbe Resul  tat erhalten, wenn das     Natriumacetat    durch       Kaliumacetat    oder     kalzinierte        Alkalikarbonate     oder     Magnesiumoxyd    und das Kupferacetat  durch andere Kupferverbindungen oder me  tallisches Kupfer ersetzt wird.



  <B> Additional patent </B> to main patent No. 156755. Process for the production of a vat dye of the anti-liraequinone series. It has been found that a new vat dye of the anthraquinone series is obtained if 1 mole of 4-amino-4'-chloro-2,1-anthraquinone thioxanthone is allowed to act on 1 mole of 1-benzoylamino-3-halogenanthraquinone.



  The new dye is a dark powder which, after reprecipitation from concentrated sulfuric acid, dyes cotton from the vat in strong gray tones of very good fastness.



       Example .: 10 '.feile 1 -benzoylamino-3-bromoanthraquinone, 10 parts of 4-amino-4'-chloi - 2,1-anthraquinone thioxanthone, 5 parts of anhydrous sodium acetate, 1 part of copper acetate and 400 parts of nitrobenzene are boiled for 20 hours on the reflux condenser. The reaction product is filtered off while still warm, finitely nitrobenzene, alcohol and finally washed with hot water.



  The same dye is obtained if 1-berizoylamino-3-chloroanthraquinone is used instead of 1-ber) zuylamino.3-bromoanthraquinone. Likewise, the same result is obtained if the sodium acetate is replaced by potassium acetate or calcined alkali metal carbonates or magnesium oxide and the copper acetate by other copper compounds or metallic copper.
