      Zusatzpatent    zum     Hauptpatent    Nr. 206728.    Verfahren zur     Herstellung    eines Farbstoffes der     Anthraehinonreihe.       Vorliegende Erfindung     betrifft    ein Ver  fahren zur Herstellung eines neuen     Küpen-          farbstoffes    der     Antbrachinonreihe.     



  Das Verfahren ist dadurch gekennzeichnet,  dass man 1     Mol    1.8 -     Dibenzoylamino-3.6-di-          halogenanthrachinon    mit 2     Mol        1-Amino-4-          benzoylaminoanthrachinon    umsetzt. Die Um  setzung führt man vorteilhaft in Gegenwart  eines alkalischen Mittels wie     Natriumcarbonat     und zweckmässig in Gegenwart eines Kupfer  salzes und eines hochsiedenden Lösungsmittels  durch. Der neue     Farbstoff    stellt ein blaues  Pulver dar, das sich in konzentrierter Schwe  felsäure mit grüner Farbe löst. Er färbt aus  rotbrauner     Küpe    Baumwolle in blauen Tönen  an.  



  <I>Beispiel:</I>  15 Gewichtsteile     1.8-Dibenzoylamino-3.6-          dichloranthrachinon    werden mit 24 Gewichts  teilen     1-Amino-4-benzoylamirro-arrthrachinon,     20 Gewichtsteilen     Natriumcarbonat,    0,3 Ge  wichtsteilen Kupferacetat und 200 Gewichts  teilen Nitrobenzol<B>16</B> Stunden lang unter    Rühren zum Sieden erhitzt. Der in Form  eines blauen Pulvers ausgeschiedene Farb  stoff wird bei<B>500</B> abgesaugt, mit     Nitrobenzol     und Alkohol gewaschen und mit Wasser aus  gekocht. Er löst sich in konzentrierter Schwe  felsäure mit grüner Farbe. Er färbt aus rot  brauner     Küpe    Baumwolle in blauen Tönen an.



      Additional patent to main patent no. 206728. Process for the production of a dye of the anthraehinone series. The present invention relates to a process for the production of a new vat dye of the antbrachinone series.



  The process is characterized in that 1 mole of 1,8-dibenzoylamino-3,6-dihaloanthraquinone is reacted with 2 moles of 1-amino-4-benzoylaminoanthraquinone. The implementation is advantageously carried out in the presence of an alkaline agent such as sodium carbonate and expediently in the presence of a copper salt and a high-boiling solvent. The new dye is a blue powder that dissolves in concentrated sulfuric acid with a green color. He dyes cotton in blue tones from a red-brown vat.



  <I> Example: </I> 15 parts by weight of 1,8-dibenzoylamino-3.6-dichloroanthraquinone are mixed with 24 parts by weight of 1-amino-4-benzoylamirro-arrthraquinone, 20 parts by weight of sodium carbonate, 0.3 parts by weight of copper acetate and 200 parts by weight of nitrobenzene <B. Heated to the boil for> 16 hours while stirring. The dye separated in the form of a blue powder is suctioned off at <B> 500 </B>, washed with nitrobenzene and alcohol and boiled with water. It dissolves in concentrated sulfuric acid with a green color. He dyes cotton in blue tones from a red-brown vat.
