  Zusatzpatent zum Hauptpatent     Nr.   <B>136650.</B>    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden,     dass    man einen  neuen Farbstoff erhält, wenn man auf  <B>1</B>     Mol    des     5,5-Dioxy-7,7'-disulfo-1,1',2#,92-          dinaphthazins    der Formel-

    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,

  <B>1</B>     Mol        diazotierte        4-Nitro-          2-amino-l-phenol-6-sulfosäure,    hierauf  <B>1</B>     Mol        diazotierte        1-Amiiio-4-chlorbenzol-2-          sulf        osäure    einwirken     lässt    und den erhalte  nen Farbstoff mit; einem kupferabgebenden       Miltel    behandelt.    Der erhaltene Farbstoff ist ein dunkles  Pulver, das sich in Wasser mit rotblauer,  in verdünnten Alkalien mit blauer und in       konz.    Schwefelsäure mit grüner Farbe löst.

    Er färbt natürliche Seide, Baumwolle und  Kunstseiden aus regenerierter Zellulose aus  neutralem     Glaubersalzbade    in     rötlichgrauen     Tönen von sehr guten     Echtheiten.       <I>Beispiel:</I>    47, 2 Teile     5,5'-Dioxy-7,7'-disulfo-1,1',2',2-          dinaphthazin    und<B>5,0</B> Teile wasserfreie Soda  werden in<B>500</B> Teilen Wasser gelöst und  mit Ei     is    auf<B>0</B> bis<B>5 '</B> gekühlt.

   Man kombi  niert darauf mit dem     Diazokörper    aus '23,4  Teilen     4-Nitro-2-amino-l-phenol-6-sulfosäure     und, nachdem dieser verschwunden ist, mit  dem     Diazokörper    aus     24,5    Teilen     1-Amino-          4-chlorbenzol-2-suliosäure.    Nach beendeter  Kupplung wird der Farbstoff isoliert und  in<B>800</B> Teilen Wasser von<B>80</B> bis<B>90 '</B> gelöst.  Man rührt ihn einige Zeit     m-it    der Lösung           a,us    24 Teilen     krist.    Kupfersulfat und schei  det mit Kochsalz ab, filtriert und trocknet.



  Additional patent to main patent no. <B> 136650. </B> Process for the production of a new azo dye. It has been found that a new dye is obtained if one uses <B> 1 </B> mol of the 5,5-dioxy-7,7'-disulfo-1,1 ', 2 #, 92-dinaphthazine of the formula -
EMI0001.0007
    which can be obtained by acidic coupling of diazotized sulfanilic acid with 5,5'-dioxy-7,7'-disulfo-2,2'-dinaphthylamine and heating the reaction product formed,

  1 mol of diazotized 4-nitro-2-amino-1-phenol-6-sulfonic acid, which is acted upon by 1 mol of diazotized 1-amino-4-chlorobenzene-2-sulfonic acid leave and get the dye with; treated with a copper-releasing agent. The dye obtained is a dark powder that dissolves in water with red-blue, in dilute alkalis with blue and in conc. Dissolves sulfuric acid with a green color.

    It dyes natural silk, cotton and artificial silk made of regenerated cellulose from neutral Glauber's salt bath in reddish-gray tones with very good fastness properties. <I> Example: </I> 47.2 parts of 5,5'-dioxy-7,7'-disulfo-1,1 ', 2', 2-dinaphthazine and <B> 5.0 </B> parts Anhydrous soda is dissolved in <B> 500 </B> parts of water and cooled to <B> 0 </B> to <B> 5 '</B> with an egg.

   You then combine with the diazo body from '23, 4 parts of 4-nitro-2-amino-1-phenol-6-sulfonic acid and, after this has disappeared, with the diazo body from 24.5 parts of 1-amino-4-chlorobenzene -2-sulioic acid. When the coupling is complete, the dye is isolated and dissolved in <B> 800 </B> parts of water from <B> 80 </B> to <B> 90 '</B>. It is stirred for some time with the solution from 24 parts of crystalline. Copper sulphate and precipitated with table salt, filtered and dried.
