  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'-disLilfo-1,        l',2,2-diiiaphtha-          zins    der Formel  
EMI0001.0008     
    das durch saure Kupplung von     diazotierter          Sulfanilsatire    mit<B>5,</B>     5'-Dioxy-7,        7'-disulfo-2,2'-          dinaphthylamin    und Erwärmen des gebildeten  Reaktionsproduktes erhalten werden kann,

    <B>1</B>     Mol        diazotierte        6-Nitro-2-aniino-l-pheiiol-4-          sulfosäure,    hierauf<B>1</B> Hol-     diazotierte        2-Naph-          thylainin-6-sulfosäure    einwirken     lässt    und den  erhaltenen Farbstoff mit einem kupferab  gebenden Mittel behandelt.  



  Der erhaltene Farbstoff ist ein dunkles  Pulver, das sich in Wasser mit schwärzlich-    grauer, in verdünnten Alkalien mit grün  blauer und in konzentrierter Schwefelsäure  mit grüner Farbe löst. Er färbt vegetabilische  Fasern aus schwach alkalischem     Glauber-          salzbade    in sehr echten     grünlichgrauen    Tönen.

    <I>Beispiel<B>:</B></I>  47,2 Teile<B>5,</B>     5'-Dioxy-7,        7'-disulfo-1,   <B>l',</B> 2,       2-dir)-aphtbazin    werden in Gegenwart von  Soda vorerst mit dem     Diazokörper    aus 23,4  Teilen     6-Nitro-2-ainino-l-phonol-4-sulfosäui#e     zum     Monoazofarbstoff    und darauf mit dem       Diazokörper    aus<B>22,5</B> Teilen     2-Naphthylai-niii-          6-sulfosäure    zum     Disazofarbstoff    kombiniert,  dieser wird nach beendeter Kupplung isoliert.

    Man -löst in<B>1000</B> Teilen kochendem Wasser,  rührt einige Zeit zusammen mit der Lösung  aus 25 Teilen     kristallisiertein    Kupfersulfat,       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 5,5'-dioxy-7,7'-disLilfo-1, l ', 2,2-diaphthalene the formula
EMI0001.0008
    which can be obtained by acidic coupling of diazotized sulfanil satire with <B> 5, </B> 5'-dioxy-7, 7'-disulfo-2,2'-dinaphthylamine and heating the reaction product formed,

    <B> 1 </B> mol of diazotized 6-nitro-2-aniino-1-phenol-4-sulfonic acid, on which <B> 1 </B> let diazotized 2-naphthylamine-6-sulfonic acid act and treated the dye obtained with a kupferab donating agent.



  The dye obtained is a dark powder which dissolves in water with a blackish-gray color, in dilute alkalis with green-blue and in concentrated sulfuric acid with a green color. It dyes vegetable fibers from weakly alkaline Glauber's salt bath in very genuine greenish-gray tones.

    <I>Example<B>:</B> </I> 47.2 parts <B> 5, </B> 5'-Dioxy-7, 7'-disulfo-1, <B> 1 ', < In the presence of soda, / B> 2,2-dir) -aphtbazine initially becomes a monoazo dye with the diazo body from 23.4 parts of 6-nitro-2-ainino-l-phonol-4-sulfosäui # e and then with the diazo body <B> 22.5 </B> parts of 2-naphthylai-niii- 6-sulfonic acid combined to form the disazo dye, which is isolated after the coupling has ended.

    It is dissolved in 1000 parts of boiling water, stirred for some time together with the solution of 25 parts of crystallized copper sulfate, filtered and dried.
