  Verfahren zur Herstellung eines     Küpenfarbstoffes    der     Anthrachinonreihe.       Es wurde gefunden, dass man einen neuen       Kiipenfarbstoff    der     Anthrachinonreihe    erhält,  wenn man auf ein     Mol        1-Benzoylamirio-3-          halogenanthrachinon    1     Mol        1,4-Aminoinethoxy-          anthracbinon    einwirken lässt.  



  Der neue Farbstoff stellt violette Nadeln  dar, die sich in konzentrierter Schwefelsäure       mit    rein blauer Farbe lösen und     Baumwolle     aus der     Küpe    in bordeauxroten Tönen von  sehr guten Echtheitseigenschaften färben.  



  <I>Beispiel:</I>  10 kg     1-Benzoylainino-3-bromanthrachi-          non,    7 kg     1,4-Aminomethoxyanthrachinon,     5 kg     Natriumacetat,    wasserfrei, 1 kg Kupfer  acetat, 150 kg Nitrobenzol werden 6 Stun  den im Sieden gehalten. Man filtriert das       Umsetzungsprodukt    bei 50  , wäscht mit  Nitrobenzol, Alkohol und dann mit heissem  Wasser.  



  Zu demselben     Farbstoff    gelangt man,  wenn statt 1-Benzoylamino-3-bromanthrachi-         non    das     1-Benzoylamino-3-chloranthrachinon     verwendet wird. Ebenso wird dasselbe  Resultat erhalten, wenn das     Natriumacetat     durch     Kaliumacetat    oder     kalzinierte    Alkali  karbonate oder     Magnesiumoxyd    und das  Kupferacetat durch andere Kupferverbindun  gen oder metallisches Kupfer ersetzt wird.



  Process for the production of a vat dye of the anthraquinone series. It has been found that a new anthraquinone series dye is obtained if 1 mole of 1,4-aminoethoxy anthracbinone is allowed to act on one mole of 1-benzoylamirio-3-haloanthraquinone.



  The new dye represents violet needles that dissolve in concentrated sulfuric acid with a pure blue color and dye cotton from the vat in burgundy shades with very good fastness properties.



  <I> Example: </I> 10 kg 1-benzoylainino-3-bromoanthraquinone, 7 kg 1,4-aminomethoxyanthraquinone, 5 kg sodium acetate, anhydrous, 1 kg copper acetate, 150 kg nitrobenzene are kept at the boil for 6 hours . The reaction product is filtered off at 50 and washed with nitrobenzene, alcohol and then with hot water.



  The same dye is obtained if 1-benzoylamino-3-chloroanthraquinone is used instead of 1-benzoylamino-3-bromoanthraquinone. The same result is also obtained if the sodium acetate is replaced by potassium acetate or calcined alkali carbonates or magnesium oxide and the copper acetate by other copper compounds or metallic copper.
