  <B>Zusatzpatent</B> zum Hauptpatent Nr. 97059.    Verfahren zur Darstellung eines als     Farbstoff    und     Farbstoffzwischenprodukt     verwendbaren     Kondensationsproduktes    der     Anthrachinonreihe.       Es wurde gefunden, dass man ein neues,  als Farbstoff und     Farbstoffzwischenprodukt     verwendbares     Kondensationsprodukt    der     An-          thrachinonreihe    erhält, wenn man 1     Mol.          Cyanurchlorid    mit 1     Mol.        4-Amino-2,

  1-an-          thrachinonakridon    und 1     Mol.        5-Amino-2,1-          anthrachinonakridon    umsetzt und das so er  haltene Produkt mit Anilin behandelt.         Beispiel:     9,3 Teile     Cyanurchlorid    und 17 Teile     4-          Amino-2,1-anthrachinonakridon    werden in  500 Teile     Nitrobenzol    eingetragen und die  Mischung einige Zeit bei 100 bis 120'     ge=     rührt.

   Hierauf versetzt man mit 17 Teilen       5-Amino-2,1-anthrachinonakridon    und kocht  einige Zeit am     Rückflusskühler.    Die abge  kühlte Reaktionsflüssigkeit wird hierauf  filtriert, der Rückstand mit Nitrobenzol und  mit Alkohol gewaschen und getrocknet.  



  Werden 10 Teile dieses Produktes, das  noch halogenhaltig ist,     einige    Zeit mit Ani  lin gekocht, so wird das letzte Chloratom  durch einen     Anilinrest    ersetzt unter Bildung    eines neuen Kondensationsproduktes, das ein  dunkles Pulver darstellt, sich in konzentrier  ter Schwefelsäure mit     rotoranger    Farbe löst,  mit     Hydrosulfit    und Natronlauge eine     rot-          violette        Küpe    gibt, aus welcher Baumwolle  echt violett gefärbt wird.



  <B> Additional patent </B> to main patent no. 97059. Process for the preparation of a condensation product of the anthraquinone series which can be used as a dye and dye intermediate. It has been found that a new condensation product of the anthrachinone series, which can be used as a dye and dye intermediate, is obtained if 1 mole of cyanuric chloride is mixed with 1 mole of 4-amino-2,

  1-anthraquinone acridone and 1 mol. 5-Amino-2,1-anthraquinone acridone and the product thus obtained is treated with aniline. Example: 9.3 parts of cyanuric chloride and 17 parts of 4-amino-2,1-anthraquinone acridone are introduced into 500 parts of nitrobenzene and the mixture is stirred for some time at 100 to 120 '.

   17 parts of 5-amino-2,1-anthraquinone acridone are then added and the mixture is refluxed for some time. The cooled reaction liquid is then filtered, the residue is washed with nitrobenzene and with alcohol and dried.



  If 10 parts of this product, which still contains halogen, are boiled with aniline for some time, the last chlorine atom is replaced by an aniline residue, with the formation of a new condensation product, which is a dark powder that dissolves in concentrated sulfuric acid with a red-orange color Hydrosulfite and caustic soda give a red-violet vat, from which cotton is dyed really violet.

PATENTANSPRUCH: Verfahren zur Darstellung eines als Farbstoff und Farbstoffzwischenprodukt ver wendbaren Kondensationsproduktes der An- thrachinonreihe, dadurch gekennzeichnet, dass man 1 Mol. Cyanurchlorid mit 1 Mol. 4- Amino-2,1-anthrachinonakridon und 1 Mol. 5-Amino-2,1-anthrachinonakridonumsetzt und das so erhaltene Produkt mit Anilin behan delt. PATENT CLAIM: A process for the preparation of a condensation product of the anthraquinone series which can be used as a dye and dye intermediate, characterized in that 1 mole of cyanuric chloride is mixed with 1 mole of 4-amino-2,1-anthraquinone acridone and 1 mole of 5-amino-2, 1-anthraquinone acridone reacts and the product thus obtained is treated with aniline. Das neue Kondensationsprodukt stellt ein dunkles Pulver dar, löst sich in konzen trierter Schwefelsäure mit rotoranger Farbe auf, gibt mit Hydrosulfit und Natronlauge eine rotviolette Küpe, aus welcher Baum wolle echt violett gefärbt wird. The new condensation product is a dark powder, dissolves in concentrated sulfuric acid with a red-orange color, gives a red-violet vat with hydrosulfite and caustic soda, from which cotton is dyed really violet.
