  <B>Zusatzpatent</B> zum Hauptpatent Nr. 136650.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es     wurde    gefunden, dass man einen  neuen Farbstoff erhält, wenn man auf  1 Hol des 5,     5'-Dioxy-7,        7'-disulf        o-1.,1',        2:'"    2  dinaphthazins der     Formel:

       
EMI0001.0008     
    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 Hol     diazotierte        6-Nitro-          2    -     amina    -1- Phenol - 4 -     sulfosäure,    hierauf  1 Hol     diazotiertes        4-Chlor-l-aminobenzol     einwirken lässt und den erhaltenen Farbstoff  mit einem kupferabgebenden Mittel behan  delt.

      Der erhaltene Farbstoff ist ein dunkles  Pulver, das sich in Wasser, sowie ver  dünnten Alkalien mit blauer und in     konz.     Schwefelsäure mit blaugrüner Farbe löst.  Er färbt natürliche Seide, Baumwolle und  Kunstseiden aus regenerierter Zellulose aus  neutralem oder schwach alkalischem Bade  in sehr echten grauen Tönen.  



  <I>Beispiel:</I>  47, 2 Teile     5,5'-Dioxy-;7,7'-disnlfo-1,1',2',2-          dinaphthazin    und 50 Teile Soda werden in  500 Teilen Wasser gelöst und mit Eis auf 0 bis  5       gekühl.    Man     kombiniert    nun mit dem     Di-          azokörper    aus 23,4 Teilen     6-Nitro-2-amino-          1-phenol-4-sulfosäure    und, nachdem dieser  nicht mehr nachzuweisen ist, mit dem     Diazo-          körper    aus 12,

  7 Teilen     4-Chlor-l-aminobenzol.     Nach beendeter Kupplung versetzt man mit  der     gupferoxydammoniaklösung    aus     2'4    Tei  len     krist.    Kupfersulfat und     wärmt    auf<B>80'.</B>  Nach     einiger    Zeit wird filtriert und ge  trocknet.



  <B> Additional patent </B> to main patent No. 136650. Process for the production of a new azo dye. It has been found that a new dye is obtained if you add 2 dinaphthazines of the formula to 1 hol of 5, 5'-dioxy-7, 7'-disulfo-1., 1 ', 2:' "

       
EMI0001.0008
    which can be obtained by acid coupling of diazotized sulfanilic acid with 5,5'-dioxy-7,7'-disulfo-2,2'-dinaphthylamine and heating of the reaction product formed, 1 Hol diazotized 6-nitro- 2 - amina -1-phenol-4-sulfonic acid, then 1 hol diazotized 4-chloro-l-aminobenzene is allowed to act and the dye obtained is treated with a copper-releasing agent.

      The dye obtained is a dark powder that dissolves in water and dilute alkalis with blue and in conc. Sulfuric acid dissolves with a blue-green color. It dyes natural silk, cotton and rayon made from regenerated cellulose from neutral or slightly alkaline baths in very real gray tones.



  <I> Example: </I> 47.2 parts of 5,5'-dioxy-; 7,7'-disnlfo-1,1 ', 2', 2-dinaphthazine and 50 parts of soda are dissolved in 500 parts of water and Chilled to 0 to 5 with ice. It is now combined with the diazo body from 23.4 parts of 6-nitro-2-amino-1-phenol-4-sulfonic acid and, after this can no longer be detected, with the diazo body from 12,

  7 parts of 4-chloro-1-aminobenzene. After the coupling is complete, the gupferoxydammoniaklösung from 2'4 parts of crystalline is added. Copper sulfate and warms up to <B> 80 '. </B> After a while, it is filtered and dried.
