Description

  

      Zusatzpatent    zum Hauptpatent Nr. 208544.    Verfahren zur Herstellung eines     stickstoffhaltigen        Kondensationsproduktes.       Es wurde gefunden, dass man ein     stick-          stoffhaltiges    Kondensationsprodukt herstel  len kann, wenn man 1     Mol        1,3-Dihalogen-2-          methylanthracIiinon    mit 2     Mol        5-Amino-1,1'-          anthrimid        umsetzt.    Der neue Farbstoff ist  ein dunkelbraunes Pulver,

   das sich in Schwe  felsäure mit graugrüner Farbe löst und  Baumwolle aus rotbrauner     Küpe        in    rötlich  grauen Farbtönen färbt.  



  Als     1,3-Dihalogen-2-methylanthrachinon     kann beispielsweise     1,3-Dichlor-2-methyl-          anthrachinon    verwendet werden.  



  Die     Umsetzung    mit 5 -     Amino,-1,1'-          anthrimid    erfolgt zweckmässig in Gegen  wart von     Lösungs-    oder     Verteilungsmitteln,     zum Beispiel Nitrobenzol,     Dichlorbenzol    oder  Naphthalin und in Gegenwart von Katalysa  toren, wie Kupfer oder Kupferverbindungen,  sowie vorzugsweise in     Anwesenheit    von  säurebindenden     Mitteln,    wie     Natriumacetat     und     Alkalicarbonat,    bei höherer     Temperatur.       <I>Beispiel:

  </I>  14,5 Teile     1,3-Dichlor-2-methylanthra-          chinon,    34,3 Teile     5-Amino-1,1'-anthrimid,     40 Teile wasserfreies     Natriumoarbonat,    1 Teil  Kupferacetat     und    300 Teile Naphthalin wer  den 18 Stunden zum Sieden erhitzt. Das       Reaktionsprodukt    wird durch     Verdünnen    mit  Chlorbenzol und     Filtration        isoliert.  



      Additional patent to main patent No. 208544. Process for the production of a nitrogen-containing condensation product. It has been found that a nitrogen-containing condensation product can be produced if 1 mol of 1,3-dihalo-2-methylanthracionone is reacted with 2 mol of 5-amino-1,1'-anthrimide. The new dye is a dark brown powder,

   which dissolves in sulfuric acid with a gray-green color and dyes cotton from a red-brown vat in reddish-gray hues.



  1,3-dichloro-2-methyl-anthraquinone, for example, can be used as 1,3-dihalo-2-methylanthraquinone.



  The reaction with 5 - amino, -1,1'-anthrimide is expediently carried out in the presence of solvents or distributing agents, for example nitrobenzene, dichlorobenzene or naphthalene, and in the presence of cata gates such as copper or copper compounds, and preferably in the presence of acid-binding agents Agents such as sodium acetate and alkali carbonate at higher temperature. <I> example:

  </I> 14.5 parts of 1,3-dichloro-2-methylanthraquinone, 34.3 parts of 5-amino-1,1'-anthrimide, 40 parts of anhydrous sodium carbonate, 1 part of copper acetate and 300 parts of naphthalene are the 18th Heated to the boil for hours. The reaction product is isolated by dilution with chlorobenzene and filtration.
