  <B>Zusatzpatent</B> zum Hauptpatent Nr. 232371.    Verfahren zur Herstellung eines     Nüpenfarbstoffes.       Gegenstand vorliegenden Patentes ist ein  Verfahren zur Herstellung eines neuen     Kü-          penfarbstoffes    durch Umsetzung von     4-Amino-          3'.        5'-        dichloranthrachinon    - 2.1- (N) -1'.

   2'-     (N)-          benzacridon    mit dem     Halogenid    der nachste  henden Formel  
EMI0001.0011     
    Die Umsetzung wird     vorteilhaft    in Gegen  wart eines indifferenten     Lösungsmittels,    wie       Nitrobenzol,        Trichlorbenzol    oder Phenol, bei  erhöhten Temperaturen durchgeführt.  



  Der erhältliche Farbstoff färbt Baum  wolle aus weinroter     güpe    in sehr     gelbstichig     grünen Tönen von sehr guten     Echtheiten    an.  



  Das als Ausgangsmaterial benutzte Ha-         logenid    der     obenstehenden    Formel kann im  Falle des     Chlorids    aus dem     bekannten    8  Brom-2-phenol-4-ogy-6.7 -     phthaloylchinazolin     durch Umsatz mit     Hydrazinhydrat    zum ent  sprechenden     Pyrazolanthronderivat,        Benzoy-          lieren    der     NH-Gruppe    und nachfolgende Be  handlung mit     Phosphorpentachlorid    in einem  indifferenten     organischenLösungsmittel,    zum  Beispiel Nitrobenzol oder     Trichlorbenzol,

      her  gestellt werden. Es muss dahingestellt blei  ben, ob die     Benzoylgruppe    bei einer der  nachfolgenden Operationen abgespalten wird  oder nicht.  



  <I>Beispiel:</I>  29 Gewichtsteile des Chlorids der Formel  
EMI0001.0033     
      und 15 Gewichtsteile     4-Amino-3'.5'-dichlor-          anthrachinon-'2.1-    (N) -1'. 2'- (N)     -benzacridon     werden in 350 Gewichtsteilen Phenol bis zur  Beendigung der     Salzsäureentwicklung    zum  Sieden erhitzt. Dann wird die Schmelze bei  130  mit warmem Nitrobenzol verdünnt und  bei 90  abgesaugt. Der Farbstoff (olivgrüne       Nädelchen)    wird durch Auskochen mit     Pyri-          din    gereinigt und durch     Verpasten    aus kon  zentrierter Schwefelsäure auf die übliche  Weise in einen Färbeteig übergeführt.

   Er  färbt Baumwolle aus weinroter     Küpe    in sehr       gelbstichig    grünen Tönen von sehr guten       Echtheiten.  



  <B> Additional patent </B> to main patent no. 232371. Process for the production of a pebble dye. The present patent relates to a process for the production of a new vat dye by reacting 4-amino-3 '. 5'-dichloroanthraquinone - 2.1- (N) -1 '.

   2'- (N) - benzacridone with the halide of the following formula
EMI0001.0011
    The reaction is advantageously carried out in the presence of an inert solvent, such as nitrobenzene, trichlorobenzene or phenol, at elevated temperatures.



  The available dye dyes cotton from wine-red güpe in very yellowish green shades of very good fastness properties.



  The halide of the above formula used as starting material can, in the case of the chloride, from the known 8 bromo-2-phenol-4-ogy-6.7-phthaloylquinazoline by reaction with hydrazine hydrate to form the corresponding pyrazolanthrone derivative, benzoylate the NH group and the following Treatment with phosphorus pentachloride in an inert organic solvent, for example nitrobenzene or trichlorobenzene,

      getting produced. It remains to be seen whether the benzoyl group is split off in one of the subsequent operations or not.



  <I> Example: </I> 29 parts by weight of the chloride of the formula
EMI0001.0033
      and 15 parts by weight of 4-amino-3'.5'-dichloro-anthraquinone-'2.1- (N) -1 '. 2'- (N) -benzacridone are heated to boiling in 350 parts by weight of phenol until the evolution of hydrochloric acid has ended. Then the melt is diluted at 130 with warm nitrobenzene and sucked off at 90. The dye (olive-green needles) is cleaned by boiling with pyridine and converted into a dyed paste in the usual way by pasting concentrated sulfuric acid.

   It dyes cotton from a wine-red vat in very yellowish green tones with very good fastness properties.
