Description

  

  Verfahren zur Herstellung eines neuen metallhaltigen     Farbstoffes.       Es     wurde    gefunden, dass man einen  neuen metallhaltigen Farbstoff erhält, wenn  man die     Chromverbindung    des     Monoazofarb-          stoffes    der Formel:  
EMI0001.0006     
    in alkalischem Medium mit     diazotierter        4-          Nitro-2-amino-l-plienol-6-sulfosäure    vereinigt  und den erhaltenen chromhaltigen     Disazo-          farbstoff    mit einem chromabgebenden     Mittel     behandelt.  



  Der -erhaltene metallhaltige Farbstoff       .stellt    ein dunkel gefärbtes Pulver dar, das  sich in Wasser und verdünnten     Alkalien    mit  blaugrüner, in konzentrierter Schwefelsäure  mit schwarzvioletter Farbe löst und Viskose  in egalen blaugrünen     \Fönen    färbt.

      <I>Beispiel:</I>    50 Teile der Chromverbindung des durch  Kuppeln in Gegenwart von Säure aus     5-          Nitro-2-diazo-l-phenol    und     2-Amino-5-oxy-          naphthalin-7-sulfosäure    erhaltenen Farbstof  fes werden zusammen mit 25 Teilen Soda  in 300 Teilen Wasser gelöst und mit der       Diazoverbindung    aus 25 Teilen     4-Nitro-2-          amino-l-phenol-6-sulfosäure    kombiniert. Der  Farbstoff wird nach beendeter Kupplung       neutralisiert    und mit     Kochsalz    abgeschieden.

      Der so erhaltene Farbstoff wird dar  auf in 1000 Teilen Wasser gelöst, mit einer       Fluorchromlösung,    entsprechend 12 Teilen       Cr203,    versetzt und das Ganze einige Stun  den am     Rückflusskühler    erwärmt. Die neue  Chromverbindung des     Disazofarbstoffes    wird  mit Salz ausgefällt, filtriert und getrocknet.



  Process for the production of a new metal-containing dye. It has been found that a new metal-containing dye is obtained if the chromium compound of the monoazo dye of the formula:
EMI0001.0006
    combined in an alkaline medium with diazotized 4-nitro-2-amino-1-plienol-6-sulfonic acid and treated the chromium-containing disazo dye obtained with a chromium donating agent.



  The metal-containing dye obtained is a dark-colored powder which dissolves in water and dilute alkalis with a blue-green color, in concentrated sulfuric acid with a black-violet color, and colors viscose in level blue-green \ hairdryers.

      <I> Example: </I> 50 parts of the chromium compound of the dye obtained by coupling in the presence of acid from 5-nitro-2-diazo-1-phenol and 2-amino-5-oxynaphthalene-7-sulfonic acid dissolved together with 25 parts of soda in 300 parts of water and combined with the diazo compound of 25 parts of 4-nitro-2-amino-1-phenol-6-sulfonic acid. After the coupling has ended, the dye is neutralized and deposited with common salt.

      The dye obtained in this way is then dissolved in 1000 parts of water, a fluorochrome solution, corresponding to 12 parts of Cr 2 O 3, is added and the whole is heated for a few hours on the reflux condenser. The new chromium compound of the disazo dye is precipitated with salt, filtered and dried.
