Description

  

  Verfahren zur Darstellung eines     stickstoffhaltigen    Kondensationsproduktes.    Das Hauptpatent betrifft ein Verfahren  zur Darstellung eines wertvollen     stickstoff-          lialtigen    Kondensationsproduktes bei dem       Bz1-a-Anthrachinonylamino-8-azabenzantbron     mit einem alkalisch wirkenden Kondensations  mittel behandelt wird.  



  Es wurde nun gefunden, dass man ein  ähnlich wertvolles stickstoffhaltiges Konden  sationsprodukt erhalten kann, wenn man das  aus 1     Mol        Bzl-Halogeii-Bz3-azabenzanthron     und 1     Mol        a-Aminoanthrachinon    erhältliche  Kondensationsprodukt mit einem alkalisch  wirkenden Kondensationsmittel, wie     Ätzal-          kali,        Alkalialkoholat,        Anilinnatrium,    Natrium  amid usw., behandelt.  



  Das Kondensationsprodukt ist neu, löst  sich in konzentrierter Schwefelsäure mit gelb  grüner Farbe und färbt die     pflanzliche    Faser  aus     rotstichig    blauer     Küpe    in echten blau  grünen     Tünen.       <I>Beispiel</I>  Man trägt 20 Teile des aus 1     Mol        Bzl-          Bi#om-Bz3-azabenzanthi-on    (hergestellt durch       Bromieren    von     Bz3-Aza-benzanthron    in     Nitro-          benzol    bei Gegenwart von Jod und 1     Mol          a-Aminoantbrachinon    erhältlichen Kondensa  

  tionsproduktes in eine 145   C heisse Schmelze  aus 200 Teilen     Ätzkali    und 160 Teilen     Äthyl-          alkohol    unter Rühren ein und erhitzt nach  beendetem Eintragen noch so lange, bis kein  unverändertes Ausgangsmaterial mehr nach  weisbar ist. Darauf nimmt man die Schmelze  mit heissem Wasser auf, scheidet etwa in  reduzierter Form vorliegende Anteile des  Reduktionsproduktes durch Einblasen von  Luft ab, saugt ab und wäscht neutral.



  Process for the preparation of a nitrogen-containing condensation product. The main patent relates to a process for the preparation of a valuable nitrogen-lialtigen condensation product in which Bz1-a-anthraquinonylamino-8-azabenzantbron 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-Halogeii-Bz3-azabenzanthrone and 1 mol of a-aminoanthraquinone with an alkaline condensing agent, such as caustic potash, alkali metal alcoholate, Aniline sodium, sodium amide, etc., treated.



  The condensation product is new, it dissolves in concentrated sulfuric acid with a yellow-green color and dyes the vegetable fiber from the reddish blue vat in real blue-green tones. <I> Example </I> 20 parts of the from 1 mol of Bzl-Bi # om-Bz3-azabenzanthi-one (prepared by brominating Bz3-aza-benzanthrone in nitrobenzene in the presence of iodine and 1 mol of a- Aminoantbrachinon available condensate

  tion product into a 145 C hot melt of 200 parts of caustic potash and 160 parts of ethyl alcohol with stirring and, after the addition is complete, heated until no more unchanged starting material can be detected. The melt is then taken up with hot water, any proportions of the reduction product present in reduced form are separated off by blowing in air, suctioned off and washed neutral.
