      Zusatzpatent    zum     T$auptpatent    Nr. 244058.         Gegenstand    des vorliegenden Zusatz  patentes ist ein Verfahren zur     Herstellung     eines     Trisazofarbstoffes,    dadurch gekenn-    zeichnet, dass der     diazotierte        Disazofarbstoff     der     Formel     
EMI0001.0009     
    mit dem     ternären        Triazinkondensationspro-          dukt    aus 1     Mol        Cyanurehlorid,    1     Mol    2  Amino-5-oxynaphthalin-7-sulfonsäure,

   1     Mol          1-Aminobenzol-3-sulfonsäure    und 1     Mol    1  N-Methylaminobenzol in alkalischer Lösung  vereinigt wird.  



  Der neue Farbstoff bildet ein dunkles  Pulver, das Baumwolle in schwach alkali  schem Bade bei Gegenwart von Kupfersulfat  und weinsaurem Natrium in waschechten       rotstichig    grauen Tönen färbt.  



       Beispiel:     <B>15,3</B>     Gew.-Teile    1-     Amino    - 3 -     carboxy    -     4-          oxybenzol    werden in üblicher     Weise        diazo-          tiert    und bei Gegenwart von     Natriumacetat     mit 22,3     Gew.-Teilen        1-Naphthylamin-7-sul-          fonsKure,    die als     Natriumsalz    in 200     Gew.-          Teilen    Wasser gelöst wurden, bei 0  gekup  pelt.

   Der sich abscheidende     Monoazofarbstoff     wird dann mit wässeriger Natronlauge in  Lösung gebracht, mit 6,9     Gew.-Teilen    Na  triumnitrit in 25%iger Lösung versetzt und    das Gemisch zu einer Mischung von 200       Gew.-Teilen    Eiswasser und 50     Gew.-Teilen          konz.    Salzsäure zulaufen gelassen.

   Ist die       Diazotierung,    die bei 0--5  durchgeführt  wird, beendet, so wird die     mittels    Kochsalz  abgeschiedene     Diazoverbindung    abgesaugt  und mit 14,8     G.ew.-Teilen        1-Naphthylamin,     die in 12     Gew.-Teilen        konz.    Salzsäure und  150     Gew.-Teilen    warmem Wasser gelöst  wurden,     vereinigt.    Während der Kupplung  werden 20     Gew.-Teile        Natriumacetat    einge  streut und das Produkt nach     einiger    Zeit mit       Kochsalz    abgeschieden.

   Es     wird    mit etwas       Natronlauge    in Lösung gebracht, mit 6,9       Gew.-Teilen        Natriumnitrit    in 25 %     iger    Lö  sung versetzt und dieses Gemisch mit einer  Mischung von 200     Gew.-Teilen    Eiswasser  und 50     Gew.-Teilen        konz.    Salzsäure bei 15   weiter     diazotiert.    Die abgesaugte     Diazover-          bindung        wird    alsdann mit 58     Gew.-Teilen     des in bekannter Weise     hergestellten        Triazin-    

        kondensationsproduktes    aus 1     Mol        Cyanur-          chlorid,    1     Mol        2-Amino-5-oxynaphthalin-7-          sulfonsäure,    1     Mol    1-Aminobenzol-3-sulfon-      säure und 1     Mol        N-Methylanilin    in     natrium-          ca,rbonat-alkalischer    Lösung     vereinigt.    Nach  beendeter Kupplung     wird    der Farbstoff ab  geschieden und     getrocknet.  



      Additional patent to main patent no. 244058. The subject of the present additional patent is a process for the production of a trisazo dye, characterized in that the diazotized disazo dye of the formula
EMI0001.0009
    with the ternary triazine condensation product from 1 mole of cyanuric chloride, 1 mole of 2-amino-5-oxynaphthalene-7-sulfonic acid,

   1 mol of 1-aminobenzene-3-sulfonic acid and 1 mol of 1 N-methylaminobenzene are combined in an alkaline solution.



  The new dye forms a dark powder that dyes cotton in a slightly alkaline bath in the presence of copper sulphate and tartrate of sodium in washable reddish gray tones.



       Example: 15.3 parts by weight of 1-amino-3-carboxy-4-oxybenzene are diazotized in the usual way and, in the presence of sodium acetate, with 22.3 parts by weight of 1-naphthylamine -7-sulphonic acid, which was dissolved as the sodium salt in 200 parts by weight of water, kup pelt at 0.

   The deposited monoazo dye is then brought into solution with aqueous sodium hydroxide solution, 6.9 parts by weight of sodium nitrite in 25% solution are added and the mixture is concentrated to a mixture of 200 parts by weight of ice water and 50 parts by weight. Allowed hydrochloric acid to run in.

   When the diazotization, which is carried out at 0-5, has ended, the diazo compound deposited by means of sodium chloride is filtered off with suction and treated with 14.8 parts by weight of 1-naphthylamine, which is concentrated in 12 parts by weight. Hydrochloric acid and 150 parts by weight of warm water were dissolved, combined. During the coupling, 20 parts by weight of sodium acetate are sprinkled in and the product is deposited after some time with sodium chloride.

   It is brought into solution with a little sodium hydroxide solution, treated with 6.9 parts by weight of sodium nitrite in 25% solution and this mixture with a mixture of 200 parts by weight of ice water and 50 parts by weight of conc. Hydrochloric acid further diazotized at 15. The suctioned off diazo compound is then mixed with 58 parts by weight of the triazine compound prepared in a known manner

        condensation product of 1 mole of cyanuric chloride, 1 mole of 2-amino-5-oxynaphthalene-7-sulfonic acid, 1 mole of 1-aminobenzene-3-sulfonic acid and 1 mole of N-methylaniline combined in sodium carbonate-alkaline solution. After the coupling has ended, the dye is separated off and dried.
