Description

  

      Zusatzpatent    zum Hauptpatent Nr. 133478.    Verfahren zur Herstellung eines neuen metallhaltigen Farbstoffes.    Es     wurde    gefunden, dass man einen  neuen, wertvollen metallhaltigen     Azof        arb-          stoff    erhält, wenn man den     Polyazofarbstoff     aus 1     Mol.        diazotiertem        4-Chlor-2.-amino-l-          phenol,    1     Mol.        diazotierter        Pikraminsäure    und  1     Mol.    2,1' -     Azonaphthalin    - 5,

  5' -     dioxy    - 2'     -          arnino-7,7'-disulfosäure    mit Chrom- und kup  ferabgebenden Mitteln     behandelt.     



  Der neue metallhaltige Farbstoff ist  trocken ein dunkles Pulver, das sich in  Wasser,     verdünnten    Alkalien und     in    kon  zentrierter Schwefelsäure mit     grünstichig          grauer    Farbe löst. Baumwolle und Viskose  werden aus neutralem oder schwach alkali  schem     Glaubersalzbad    in     echten    Grautönen  egal angefärbt.  



       Beispiel:     53,5 Teile des Farbstoffes     2,1'-Az3naph-          tha-lin-        5,5'-.dioxy-        2'-amino    - 7,7' -     disulfosäure     werden zusammen     mit,50        Teilen,Soda    in 600  Teilen Wasser gelöst.

   Bei<B>6-8'</B> gibt man  die     Diazoverbindung    .aus 14,4 Teilen     4-Chlor-          ?-amino-phenol        zu    und nach einiger Zeit    noch die     Diazoverbindung    aus 19,9 Teilen       Pikraminsäure.    Nach 16     Stunden.    wird der  gebildete     Azofarbstoff    filtriert.  



  Man löst den     A@zofarbstoff    in 4000 Teilen  Wasser, versetzt mit 7,6 Teilen     Cr2Q    als       F'luorchromlösung    und erhitzt 24     Stunden     zum     ,Sieden.    Nach     ,Zugabe    von 30 Teilen  Kupfersulfat erhält man einen Chrom- und  kupferhaltigen Farbstoff, der     wie    üblich     iso-          liert    werden kann.



      Additional patent to main patent No. 133478. 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 1 mole of diazotized 4-chloro-2-amino-1-phenol, 1 mole of diazotized picric acid and 1 mole of 2, 1 '- azonaphthalene - 5,

  5 '- dioxy - 2' - arnino-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, diluted alkalis and in concentrated sulfuric acid with a greenish gray color. Cotton and viscose are dyed in real gray tones from a neutral or slightly alkaline Glauber's salt bath.



       Example: 53.5 parts of the dye 2,1'-az3naphtha-lin-5,5 '-. Dioxy-2'-amino-7,7' - disulfonic acid are mixed with 50 parts of soda in 600 parts of water solved.

   At <B> 6-8 '</B>, the diazo compound from 14.4 parts of 4-chloro-? -Amino-phenol is added and, after a while, the diazo compound from 19.9 parts of picric acid is added. After 16 hours. the azo dye formed is filtered.



  The azo dye is dissolved in 4000 parts of water, 7.6 parts of Cr2Q as fluorochromium solution are added and the mixture is heated to boiling for 24 hours. After adding 30 parts of copper sulphate, a chromium and copper-containing dye is obtained which can be isolated as usual.
