  Verfahren zur Darstellung eines neuen, stickstoffhaltigen     Küpenfarbstoffes.       Es wurde gefunden,     :dass    man einen neuen,  stickstoffhaltigen     Küpenfarbstoff    erhalten  kann, wenn man 1     Mol.        Tetrakalogen-all:o-          ms-nap,hto,dianthron,    :dargestellt     @durch    Halo  genieren .von     a.ll,o-ms-naphto:

  dianthron,    mit  4     Mol.    einer     verseifba.ren    organischen Ver  bindung des Ammoniaks, zum Beispiel p  T'oluolsulfamid, behandelt und den     orga.ni-          ,ehen    Rest durch Verseifen abspaltet, zum       13f.ispie1        :dure:h        Umlösen    aus Schwefelsäure.  



  Die Kondensation wird zweckmässig in       Lösu.nga-    oder     Suspensioasmitteln    und in An  oder     Abwesenheit    von     säurebindenden    Mit  teln ausgeführt. Als     Lösungs-    oder     Suspen-          sionsmittel    kommen besonders solche von  hohem     Siedepunkt,    wie Nitrobenzol oder       Naphtalin,    in Betracht. Es ist     vorteilhaft,     während, der Reaktion     Katalysatoren,    wie  zum Beispiel Kupferkarbonat oder Kupfer  oxyd, zuzusetzen..  



  Der neue     stickstoffhaltige        Küpenfa.rb-          Stoff    ist ein violettes Pulver, das     @s@ich    in    konzentrierter Schwefelsäure mit grüner  Farbe löst und Baumwolle aus violetter     Küpe     in grauvioletten, chlorechten Tönen färbt.  



  <I>Beispiel:</I>  70 Teile     Tetrabrom-allo-ms-naphtodian-          thron    werden in 700 Teilen Nitrobenzol mit.  30 Teilen     Natrium.a:cetat,    5 Teilen Kupfer  karbonat und 100 Teilen     p-Tioluo:lsulfami@d     unter     .Rühren    1.2     Stunden    lang gekocht. Nach  dem Erkalten sangt man ab     und,    löst den  dunkelvioletten Rückstand bei 80-100   aus  konzentrierter Schwefelsäure um.



  Process for the preparation of a new, nitrogenous vat dye. It has been found that: a new, nitrogen-containing vat dye can be obtained if 1 mol. Tetrakalogen-all: o-ms-nap, hto, dianthron,: represented @ by halogenating. Von a.ll, o-ms- naphto:

  dianthrone, treated with 4 moles of a saponifiable organic compound of ammonia, for example toluenesulfamide, and the organic residue is split off by saponification, for the 13th example: dure: h dissolving from sulfuric acid.



  The condensation is expediently carried out in solvents or suspending agents and in the presence or absence of acid-binding agents. Particularly suitable solvents or suspending agents are those with a high boiling point, such as nitrobenzene or naphthalene. It is advantageous to add catalysts such as copper carbonate or copper oxide during the reaction.



  The new nitrogen-containing Küpenfa.rb substance is a violet powder that @ s @ ich dissolves in concentrated sulfuric acid with a green color and dyes cotton from a violet vat in gray-violet, chlorine-like shades.



  <I> Example: </I> 70 parts of tetrabromo-allo-ms-naphtodian- thron are mixed with 700 parts of nitrobenzene. 30 parts of sodium a: acetate, 5 parts of copper carbonate and 100 parts of p-Tioluo: Isulfami @ d boiled with stirring for 1.2 hours. After cooling, you sang and dissolve the dark purple residue at 80-100 from concentrated sulfuric acid.
