Description

  

  Verfahren zur Darstellung eines     stickstoffhaltigen    Kondensationsproduktes.    Das Hauptpatent betrifft ein Verfahren  zur Darstellung eines wertvollen stickstoff  haltigen Kondensationsproduktes, bei dem       Bzl-a-Anthrachinonylamino-8-azabenzanthron     mit einem alkalisch wirkenden Kondensa  tionsmittel behandelt wird.  



  Es wurde nun gefunden, dass man ein  ähnlich wertvolles stickstoffhaltiges Konden  sationsprodukt erhalten kann, wenn man das  aus 1     Mol        Bzl-Halogen-S-azabenzanthron    und  1     Mol        1-Amino-5-methylaminoanthrachinon     erhältliche Kondensationsprodukt mit einem  alkalisch wirkenden Kondensationsmittel, wie       Ätzalkali,        Alkalialkoholat,        Anilinnatrium,          Natriumamid    usw., behandelt.  



  Das Kondensationsprodukt ist neu, löst  sich in konzentrierter Schwefelsäure mit  schwarzvioletter Farbe und färbt die pflanz  liche Faser aus     violettblauer        Küpe    in grün  grauen Tönen.  



  <I>Beispiel:</I>  40 Teile des Kondensationsproduktes aus       Bzl-Brom-8-azabenzanthron    und     1-Amino-5-          methylaminoanthrachinon    werden in einer    Schmelze aus 200 Teilen     Ätzkali    und 160  Teilen Äthylalkohol mehrere Stunden lang  auf     140-1450    C erhitzt. Dann nimmt man  die Schmelze mit Wasser auf, oxydiert die  teilweise entstandene     Leukoverbindung    des  Reaktionsproduktes durch Einleiten von Luft  und saugt den ausgeschiedenen Farbstoff ab.



  Process for the preparation of a nitrogen-containing condensation product. The main patent relates to a method for the preparation of a valuable nitrogen-containing condensation product, in which Bzl-a-anthraquinonylamino-8-azabenzanthrone is treated with an alkaline condensation agent.



  It has now been found that a similarly valuable nitrogen-containing condensation product can be obtained if the condensation product obtainable from 1 mol of Bzl-halogen-S-azabenzanthrone and 1 mol of 1-amino-5-methylaminoanthraquinone with an alkaline condensing agent, such as caustic alkali, Alkali alcoholate, aniline sodium, sodium amide, etc.



  The condensation product is new, dissolves in concentrated sulfuric acid with a black-violet color and colors the vegetable fiber from the violet-blue vat in green-gray tones.



  <I> Example: </I> 40 parts of the condensation product of Bzl-bromo-8-azabenzanthrone and 1-amino-5-methylaminoanthraquinone are heated in a melt of 200 parts of caustic potash and 160 parts of ethyl alcohol to 140-1450 C for several hours . The melt is then taken up with water, the partially formed leuco compound of the reaction product is oxidized by passing in air and the dyestuff which has separated out is filtered off with suction.
