Description

  

  Verfahren zur Darstellung eines stickstoffhaltigen     Küpenfarbstoffes.       Es wurde gefunden, dass man einen sehr  wertvollen neuen     Küpenfarbstoff    erhält; wenn  man     Trihalogenpyranthron    hergestellt durch       Halogenieren    von     Pyranthron    in     Chlorsulfon-          säure    mit     1-Aminoanthrachinon    in der Weise  umsetzt, dass 1     Mol.        Trihalogenpyranthron     mit 3     Mol.        Aminoanthrachinon    reagiert.

   Der  Farbstoff entsteht zum Beispiel in vorzüglicher  Ausbeute, wenn man das     Trihalogenpyran-          thron    mit     1-Aminoanthrachinon    erhitzt, wo  bei es vorteilhaft ist, in Gegenwart hochsie  dender Lösungsmittel zu arbeiten. Statt  hochsiedender Lösungsmittel kann man auch  hochsiedende Verdünnungsmittel anwenden,  und es ist oftmals auch von Vorteil, wenn  bei der Umsetzung die Reaktion fördernde       Stoffe,    wie Katalysatoren, säurebindende Mittel       etc.    zugegen sind.  



  Der neue     Küpenfarbstoff    enthält kein  Halogen mehr. Er stellt ein     violettschwarzes     Pulver dar, das sich in konzentrierter Schwe  felsäure mit blauvioletter Farbe löst und    Baumwolle aus violetter     Küpe    in violett  schwarzen Tönen anfärbt.  



       Beispiel:     Man kocht während 8 Stunden unter  Rühren eine Suspension von 64 Teilen     Tri-          brompyranthron,    30 Teilen     Natriumacetat,     10 Teilen Kupferkarbonat und 66 Teilen 1  Aminoanthrachinon in 500 Teilen Nitrobenzol.  Nach dem Erkalten saugt man ab und ent  fernt aus dem Rückstand die anorganischen  Bestandteile mit Wasser.



  Process for the preparation of a nitrogenous vat dye. It has been found that a very valuable new vat dye is obtained; when trihalopyranthrone prepared by halogenating pyranthrone in chlorosulfonic acid is reacted with 1-aminoanthraquinone in such a way that 1 mole of trihalopyranthrone reacts with 3 moles of aminoanthraquinone.

   The dye is produced in excellent yield, for example, if the trihalopyranothrone is heated with 1-aminoanthraquinone, where it is advantageous to work in the presence of high-boiling solvents. Instead of high-boiling solvents, high-boiling diluents can also be used, and it is often also advantageous if substances which promote the reaction, such as catalysts, acid-binding agents, etc., are present during the reaction.



  The new vat dye no longer contains halogen. It is a violet-black powder that dissolves in concentrated sulfuric acid with a blue-violet color and dyes cotton from a violet vat in violet-black tones.



       Example: A suspension of 64 parts of tribromopyranthrone, 30 parts of sodium acetate, 10 parts of copper carbonate and 66 parts of 1 aminoanthraquinone in 500 parts of nitrobenzene is boiled for 8 hours while stirring. After cooling, it is filtered off with suction and the inorganic constituents are removed from the residue with water.
