      Zusatzpatent    zum Hauptpatent Nr. 136650.    Verfahren zur Herstellung eines neuen     Azofarbstoffes>       Es wurde gefunden, dass man einen  neuen Farbstoff erhält, wenn man auf  1;     Mol    des     5,5'-Dioxy-7,7'-disulfo-1,1',2',2-          dinaphthazins.    der Formel:

    
EMI0001.0006     
    das durch saure Kupplung von     diazotier-          ter        Sulfanilsäure    mit     5,5'-Dioxy-7,7'-di-          sulfo-2,2'-dinaphthylamin    und Erwärmen  des gebildeten Reaktionsproduktes erhalten  werden kann, 1     Mol        diazotierte        4-Nitro-          2    -     amino    -1-     phenol    - 6 -     sulfosäure,

      hierauf  1     Mol    eines     diazotierten    Gemisches von       2-Naphthylamin-5-    und     2-Napththylamin-8-          sulfosäure    einwirken lässt und den erhalte  nen Farbstoff mit einem kupferabgebenden  Mittel behandelt.    Der erhaltene Farbstoff ist ein dunkel  bronziges Pulver, das sich in Wasser mit       schwärzlichvioletter,    in verdünnten Alkalien  mit blauer und in     konz.    Schwefelsäure mit       grüner    Farbe löst.

   Er färbt natürliche Seide,       Baumwolle    und Kunstseiden aus regenerier  ter Zellulose aus neutralem oder schwach  alkalischem     Glaubersalzbade    in echten grauen  Tönen.  



  <I>Beispiel:</I>  47,2 Teile     5,5'-Dioxy-7,7'-disulfo-1,1',2',2-          dinaphthazin    und 50 Teile wasserfreie Soda  werden in -500 Teilen Wasser gelöst und  mit Eis auf 0 bis 5   gekühlt. Man kom  biniert mit dem     Diazokörper    aus 23,4 Tei  len 4 -     Nitro    - 2 -     amino-l-phenol-6-sulfosäure     und, nachdem dieser nicht mehr nachzuwei  sen ist, mit einem Gemisch der     Diazokörper     aus 22,

  5 Teilen     2-Naphthylamin-5-    und     2-          Naphthylamin-8-sulfosäure.    Nach beendeter  Kupplung versetzt man mit der Kupfer  oxydammoniaklösung aus 24 Teilen     krist.         Kupfersulfat, wärmt auf 80   auf, salzt den  Farbstoff aus, filtriert und trocknet.



      Additional patent to main patent no. 136650. Process for the preparation of a new azo dye> It has been found that a new dye is obtained if one clicks on 1; Moles of 5,5'-dioxy-7,7'-disulfo-1,1 ', 2', 2-dinaphthazine. the formula:

    
EMI0001.0006
    which can be obtained by acidic coupling of diazotized sulfanilic acid with 5,5'-dioxy-7,7'-disulfo-2,2'-dinaphthylamine and heating of the reaction product formed, 1 mol of diazotized 4-nitro-2 - amino -1-phenol-6-sulfonic acid,

      then 1 mole of a diazotized mixture of 2-naphthylamine-5- and 2-naphthylamine-8-sulfonic acid can act and the dye obtained is treated with a copper donor. The dye obtained is a dark, bronzy powder that turns blackish-violet in water, blue in dilute alkalis and blue in conc. Dissolves sulfuric acid with a green color.

   It dyes natural silk, cotton and artificial silk made from regenerated cellulose from a neutral or weakly alkaline Glauber's salt bath in real gray tones.



  <I> Example: </I> 47.2 parts of 5,5'-dioxy-7,7'-disulfo-1,1 ', 2', 2-dinaphthazine and 50 parts of anhydrous soda are dissolved in -500 parts of water and chilled to 0-5 with ice. You combine with the diazo body from 23.4 parts of 4 - nitro - 2 - amino-1-phenol-6-sulfonic acid and, after this can no longer be detected, with a mixture of the diazo body from 22,

  5 parts of 2-naphthylamine-5- and 2-naphthylamine-8-sulfonic acid. When the coupling is complete, the copper oxide ammonia solution of 24 parts of crystalline is added. Copper sulfate, warms up to 80, salt out the dye, filtered and dried.
