Description

  

  Verfahren zur Herstellung eines neuen metallhaltigen Farbstoffes.    Es wurde gefunden, dass man einen neuen,  wertvollen metallhaltigen     Azofarbstoff    erhält,  wenn man den     Polyazofarbstoff    aus 2     Mol          diazotiertem        4-Chlor-2-amirio-l-phenol    und  1     Mol        2,1'-Azorraphthalin-5,5'-dioxy_        2'-amino-          7,7'-disulfosäure    mit Chrom- und kupferab  gebenden Mitteln behandelt.  



  Der neue metallhaltige Farbstoff ist trocken  ein dunkles Pulver, das sich in Wasser,  verdünnten     Alkalien    und in konzentrierter  Schwefelsäure mit     rötlichgrauer    Farbe löst.  Baumwolle und Viskose werden aus neutralem  oder schwach alkalischem     Glaubersalzbad    in  echten rötlichen Grautönen egal anfärbt.  



       Beispiel:     53,5 Teile     Natronsalz    des     Farbstoffes    aus  einem     Mol        diazotierter        2-Amino-5-oxynaph-          thalin-7-sulfosäure    und einem     Mol        2-Amino-          5-oxynaphthalin-7-sulfosäure    (sauer gekuppelt)  werden in 500-600 Teilen Wasser gelöst  und nach Zugabe von 50 Teilen Soda bei  6-8  mit dem     Diazokörper    aus 28,7 Teilen       4-Chlor-2-aminophenol    kombiniert.

   Nach 15  Stunden wird der     Azofarbstoff    filtriert, in    3500 Teilen Wasser gelöst, mit 7,6 Teilen       Cr20s    in Form einer     Fluorchromlösung    24       Stunden    gekocht, darauf mit 30 Teilen kri  stallisiertem Kupfersulfat versetzt, eine halbe  Stunde weiter gekocht und alsdann der Farb  stoff wie üblich isoliert.



  Process for the production of a new metal-containing dye. It has been found that a new, valuable metal-containing azo dye is obtained if the polyazo dye is obtained from 2 moles of diazotized 4-chloro-2-amirio-1-phenol and 1 mole of 2,1'-azoraphthalene-5,5'-dioxy_ 2 '-amino- 7,7'-disulfonic acid treated with chromium and copper donating agents.



  The new metal-containing dye is a dry, dark powder that dissolves in water, dilute alkalis and concentrated sulfuric acid with a reddish-gray color. Cotton and viscose are dyed in a neutral or slightly alkaline Glauber's salt bath in real reddish gray tones.



       Example: 53.5 parts of the sodium salt of the dye from one mole of diazotized 2-amino-5-oxynaphthalene-7-sulfonic acid and one mole of 2-amino-5-oxynaphthalene-7-sulfonic acid (acid-coupled) are 500-600 parts Dissolved water and, after adding 50 parts of soda, combined at 6-8 with the diazo body composed of 28.7 parts of 4-chloro-2-aminophenol.

   After 15 hours, the azo dye is filtered, dissolved in 3500 parts of water, boiled with 7.6 parts of Cr20s in the form of a fluorochrome solution for 24 hours, then treated with 30 parts of crystallized copper sulfate, boiled for another half an hour and then the dye is isolated as usual .
