   Die verfahrensgemäss erhältlichen Produkte sind  äusserst wertvolle Farbstoffe, die zum Färben und
Bedrucken von Materialien aus Leder, trannierter
Baumwolle, Celluloseacetat, synthetischen Superpoly amiden und -polyurethanen, sowie zum Färben ligninhal tiger Fasern, wie Kokos, Jute und Sisal, verwendet werden können. Sie sind weiter geeignet zur Herstellung von Schreibflüssigkeiten, Stempelfarben, Kugelschrei berpasten und lassen sich auch im Gummidruck verwen den. Sie eignen sich vor allem gut zum Färben und
Bedrucken von Materialien, die ganz oder teilweise aus polymerisiertem Acrylnitril und/oder Vinylidencyanid oder aus sauer modifizierten aromatischen Polyestern bestehen und zeichnen sich hier durch sehr gute   Lieht-    echtheit, Nass-, Reib- und Sublimierechtheit aus.

  Sie besitzen weiter ein sehr gutes Ziehvermögen auf diesen
Fasern und besitzen eine gute   Überfärbeechtheit.    Die
Farbstoffe bilden mit anionischen Fällungsmitteln, wie
Tonerde, Tannin, Phosphorwolfram(molybdän)-säuren lichtechte Pigmente, die vorteilhaft im Papierdruck eingesetzt werden können.



   In den folgenden Beispielen stehen Gewichts- und
Volumteile zueinander im Verhältnis von kg zu Liter.



   Beispiel I
37,8 Gewichtsteile N-Phenvl-N-methylaminobenzo phenon, 27,2 Gewichtsteile 1-Methyl-2-phenylindol und
35 Gewichtsteile Phosphoroxvch1orid werden zusammen auf 100  C erwärmt und 3 Stunden bei dieser Tempera tur gehalten. Die noch warme Schmelze gibt man zu 600
Volumteilen 50  C warmem Wasser und stellt den pH
Wert durch Zugabe von 140 Volumteilen 200/oieer    Natriumacetatlösung    auf 2 ein. Dann vervollständigt man die Fällung des Farbstoffes durch Zugabe von 30
Gewichtsteilen Kochsalz und lässt den Ansatz einige
Stunden rühren. Das erhaltene Farbharz wird abgetrennt. in 4000 Volumteilen siedendem Wasser gelöst, die   Lösung    mit Aktivkohle geklärt und der Farbstoff, nachdem sich die Lösung etwas abgekühlt hat. durch
Zugabe von 90 Volumteilen einer Lösung von Zinkchlo rid in der gleichen Gewichtsmenge Wasser ausgefällt.

 

   Der Farbstoff wird einige Zeit gerührt,   abgesaugt    und mit 10   0/obiger    Kochsalzlösung gewaschen. Der so erhal tene Farbstoff entspricht der Formel  
EMI4.1     
 und färbt Fasern aus Polyacrylnitril in einem lichtechten, blaustichigen Grün.



   Man gelangt gleichfalls zu wertvollen Farbstoffen, wenn man in dem vorstehenden Beispiel anstelle von 1 Methyl-2-phenylindol die äquivalenten Mengen der in der nachfolgenden Tabelle angeführten Indolderivate einsetzt.

45 Gewichtsteile 4-N,N-Dimethylaminobenzophenon, 41,4 Gewichtsteile 1-Methyl-2-phenylindol und 50 Gewichtsteile Phosphoroxychlorid werden zusammengegeben und 3 Stunden auf 100   0C    erwärmt. Die noch warme Schmelze wird auf 1000 Volumteile Wasser von   50  C    ausgetragen und das   Reaktionsgemisch    mit 320 Volumteilen 20 %iger Natriumacetatlösung auf einen pH-Wert von 2 eingestellt. Nachdem sich die Lösung abgekühlt hat, fällt man den Farbstoff durch Zugabe von 100 Gewichtsteilen Kochsalz und 150 Volumteilen einer Lösung von Zinkchlorid in der gleichen Gewichtsmenge Wasser aus.

  Zur weiteren Reinigung löst man den Farbstoff in siedendem Wasser, klärt mit Aktivkohle und fällt ihn durch Zusatz von 30 Volumteilen Zinkchloridlösung. Der so erhaltene Farbstoff färbt Fasern aus Polyacrylnitril in einem lichtechten grünstichigen Blau.



   Führt man die Umsetzung nach dem oben angegebenen Verfahren mit den in der folgenden Tabelle aufgeführten Aminobenzophenonen und Indolderivaten durch, so erhält man ebenfalls Farbstoffe, die sich durch sehr gute   färberische    Eigenschaften auszeichnen.

19,7 Gewichtsteile 4-Aminobenzophenon und 14,5 Gewichtsteile 1,2-Dimethylindol werden in 200 Gewichtsteile Alkohol eingetragen und das Reaktionsgemisch bei 30    C    mit 50 Gewichtsteilen konzentrierter Salzsäure (d = 1,19) versetzt. Nachdem man den Ansatz auf 80  C erwärmt hat, rührt man ihn 3 Stunden bei dieser Temperatur. Anschliessend werden 120 Volumteile Alkohol abdestilliert und der tieffarbige Rückstand zu einer Mischung aus 250 Volumteilen gesättigter Kochsalzlösung und 250 Gewichtsteilen Eis gegeben.

 

  Man lässt die Farbstoffsuspension über Nacht rühren, saugt sie ab und reinigt den Farbstoff durch Umkristallisieren aus Wasser und Fällen mit Kochsalz.



   Anstelle des 1,2-Dimethylindols lassen sich mit Vorteil auch die nachstehenden Indole zur Herstellung von Farbstoffen nach dem obengenannten Verfahren verwenden.

100 Gew.-Teile   1 -Methyl-2-phenyl-3-benzoylindol,    58,9 Gew.-Teile   N Methyldiphenylamin    und 184 Gew. Teile Phosphoroxychlorid werden verrührt und auf 100   "C    erwärmt. Man rührt 6 h bei dieser Temperatur.



  Dann giesst man die heisse Schmelze unter Rühren in 2000 Vol.-Teile Wasser. Es wird einige Stunden gerührt und dann der Farbstoff von Wasser abgetrennt. Man löst den Rückstand in 4000 Vol.-Teilen siedenden Wassers, klärt mit A-Kohle und salzt aus durch Zugabe von 200 Gew.-Teilen Natriumchlorid.



   Der so erhaltene Farbstoff färbt Polyacrylnitrilfasern in einem lichtechten blaustichigen Grün.
