Description

  

  Verfahren zur Darstellung eines neuen, stickstoffhaltigen     Itüpenfarbstoffes.       Im Hauptpatent ist ein Verfahren zur  Darstellung eines neuen,     stickstoffhaltigen          hüpenfarbstoffes        beschrieben,    wonach man  1     Mol.        Dihalogen-allo-ms-naphtodianthron,     erhalten durch     Halogenieren    von     allo--          ms-Nap@htoid'ianthron,    mit 2     Mol.        1-Amino-          anthracIiinon        kondensiert.     



  Es wurde nun gefunden, dass ein  neuer,     stickstoffhaltiger        Küpenfarbstoff    ent  steht, wenn man 1     Mol.        Tetrahalo:gen-          allo-ms-naphtodianthron,        hergestellt    durch       Halogenieren    von     allo-ms-Naphtodianthron,     mit 4     Mol.    1.     5-Diaminoanthraehinon    kon  densiert.

   Die     Kondensation    wird zweckmässig  in     Lösungs-    oder     Suspensionsmitteln    und  in     An-    oder     Abwe--enheit    von     säurebinden--          den        Mitteln        ausgeführt.    Als     Lösungs-    oder       Suspensionsmittel    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     Küpenfarbstoff        ist    ein violett  schwarzes Pulver, das sich     in    konzentrierter  Schwefelsäure mit     :grüner    Farbe löst und  aus     violetter        güpe    Baumwolle dunkelgrau       färbt.    ,       Beispiel:

       36, Teile     Tetrabrom    -     allo    - ms -     naphto-          dianthron    werden in 720 Teilen Nitrobenzol  mit 50 Teilen     1.5-Diaminoanthrachinon    nach  Zugabe von 25 Teilen     Natriumacetat    und       2:,5    Teilen Kupferkarbonat während sechs  Stunden     unter        Rühren,    gekocht. Nach dem  Erkalten wird abgesaugt und wie üblich     au.f-          gearbeitet.  



  Process for the preparation of a new, nitrogen-containing itupe dye. The main patent describes a process for the preparation of a new, nitrogen-containing hüpen dyestuff, according to which 1 mol. Of dihalo-allo-ms-naphtodianthrone, obtained by halogenating allo-ms-Nap @ htoid'ianthrone, with 2 mol. 1-amino- condensed anthracionone.



  It has now been found that a new, nitrogen-containing vat dye is created when 1 mol .

   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 vat dye is a violet black powder that dissolves in concentrated sulfuric acid with: green color and turns violet güpe cotton into a dark gray color. , Example:

       36 parts of tetrabromo-allo-ms-naphthodianthrone are boiled in 720 parts of nitrobenzene with 50 parts of 1,5-diaminoanthraquinone after addition of 25 parts of sodium acetate and 2.5 parts of copper carbonate for six hours with stirring. After cooling, it is vacuumed and worked on as usual.
