Description

  

      Verfahren    zur Darstellung eines     Küpenfarbstoffes    der     Anthanthronreihe.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Darstellung eines neuen       Küpenfarbstoffes    der     Anthanthronreihe,    da  durch gekennzeichnet, dass man 1     Mol.        Te-          trahalogen-anthanthron    wie es erhalten wer  den kann aus     Anthanthron    durch     Haloge-          nieren    in     Oleum    mit der     nötigen    Menge Ha  logen,

   mit 4     Mol.        Monobenzoyl-1.        4-diamino-          anthrachinon    bei Gegenwart von säurebin  denden     Mitteln    und katalytisch wirkenden  Substanzen kondensiert.  



  Als Katalysatoren kann man zum Beispiel  Kupfer oder seine Verbindungen und Salze  verwenden.    <I>Beispiel:</I>  6,2 Gewichtsteile     Tetrabrom-anthanthron     (zum Beispiel hergestellt aus     Anthanthron     durch     Bromieren    in     Oleum    mit der nötigen  Menge Brom), 15 Gewichtsteile     Monobenzoyl-          1        .4-diamino-anthrachinon,

      8 Gewichtsteile  wasserfreies     Natriumacetat.    1     Gewichtsteil            Ii-Qpferchlorür    und 440 Gewichtsteile     Naph-          taliü    werden unter Rühren und     Rückfluss     einige Stunden gekocht. Man verdünnt noch  warm     finit        Toluol,    saugt ab und wäscht mit       Toluol,    dann mit Sprit und endlich mit  heissem     ammoniakalischem    Wasser nach und  trocknet.  



  Man erhält so ein blauschwarzes Pulver,  das sich in konzentrierter Schwefelsäure mit  grüner Farbe löst und das aus stumpf wein  roter     güpe    auf Baumwolle ein echtes     grün-          stichiges    Grau ergibt.



      Process for the preparation of a vat dye of the anthanthrone series. The subject of the present patent is a process for the preparation of a new vat dye of the anthanthrone series, characterized in that one mol. Tetrahalogenanthrone as it can be obtained from anthanthrone by halogenation in oleum with the necessary amount of halogen,

   with 4 moles of monobenzoyl-1. 4-diamino-anthraquinone condensed in the presence of acid-binding agents and catalytically active substances.



  Copper or its compounds and salts, for example, can be used as catalysts. <I> Example: </I> 6.2 parts by weight of tetrabromo-anthanthrone (for example made from anthanthrone by brominating in oleum with the necessary amount of bromine), 15 parts by weight of monobenzoyl-1,4-diamino-anthraquinone,

      8 parts by weight of anhydrous sodium acetate. 1 part by weight of ferric chloride and 440 parts by weight of naphthalene are boiled for a few hours with stirring and reflux. The finite toluene is diluted while it is still warm, suctioned off and washed with toluene, then with gasoline and finally with hot ammoniacal water and then dried.



  This gives a blue-black powder which dissolves in concentrated sulfuric acid with a green color and which turns a dull wine-red güpe on cotton into a real green-tinged gray.
