Description

  

  Verfahren zur Darstellung eines Farbstoffes der     Anthrachinonakridonreihe.       Es wurde gefunden, dass man einen wert  vollen Farbstoff der     Anthrachinonakridonreihe     erhalten kann, wenn man     Pentachloranthra-          chinonakridon,    das gemäss dem Verfahren des  Patentes Nr. 148119 hergestellt werden kann,  mit einem     Dialkylanilin    behandelt.  



  Das     Dialkylanilin    tritt bei dem beschrie  benen Verfahren nicht in das Molekül ein,  sondern bewirkt nur eine Entfernung von  1 Atom Chlor aus diesem.  



  Der Farbstoff löst sich in konzentrierter  Schwefelsäure mit orangegelber Farbe und  liefert eine violette     Küpe,    aus der Baumwolle  in orangegelben Tönen gefärbt wird.  



       Beispiel     2 Teile     Pentachloranthrachinonakridon,     erhältlich zum Beispiel nach dem Verfahren  des Patentes Nr. 148119, werden mit 20 Tei  len     Diäthylanilin    ca. 1 Stunde lang gekocht.  Die zuerst rote Lösung wird orangegelb, und    braungelbe Kristalle scheiden sich aus. Nach  dem Abkühlen wird das Reaktionsprodukt       abgesaugt,    mit     Diätbylanilin,    Alkohol und  Wasser gewaschen und, um es analysenrein  zu erhalten, aus     Trichlorbenzol    umkristallisiert.



  Process for the preparation of a dye of the anthraquinone acridone series. It has been found that a valuable anthraquinone acridone series dye can be obtained by treating pentachloroanthraquinone acridone, which can be prepared according to the process of Patent No. 148119, with a dialkylaniline.



  The dialkylaniline does not enter the molecule in the process described, but only removes 1 atom of chlorine from it.



  The dye dissolves in concentrated sulfuric acid with an orange-yellow color and provides a purple vat from which cotton is dyed in orange-yellow tones.



       Example 2 parts of pentachloroanthraquinone acridone, obtainable, for example, by the method of patent no. 148119, are boiled with 20 parts of diethylaniline for about 1 hour. The initially red solution turns orange-yellow and brown-yellow crystals separate. After cooling, the reaction product is filtered off with suction, washed with dietbylaniline, alcohol and water and, in order to get it analytically pure, recrystallized from trichlorobenzene.

PATENTANSPRUCH: Verfahren zur Darstellung eines Farb stoffes der Anthrachinonakridorrreihe, dadurch gekennzeichnet, dass man Pentacbloranthra- chinonakridon, das gemäss dem Verfahren des Patentes Nr. 148119 erhalten werden kann, mit einem Dialkylanilin behandelt. Der Farbstoff, ein Tetrachloranthrachinon- akridon, löst sich in konzentrierter Schwefel säure mit orangegelber Farbe und liefert eine violette Küpe, aus der Baumwolle in orangegelben Tönen gefärbt wird. PATENT CLAIM: Process for the preparation of a dye of the anthraquinone acridor series, characterized in that pentacbloranthraquinone acridone, which can be obtained according to the process of patent no. 148119, is treated with a dialkylaniline. The dye, a tetrachloranthraquinone acridone, dissolves in concentrated sulfuric acid with an orange-yellow color and provides a purple vat from which cotton is dyed in orange-yellow tones.
