  Verfahren zur Herstellung eines     Polyazofarbstoffes.       Zusatzpatent zum Hauptpatent Nr. 240225.    <B>ES</B> wurde gefunden, dass man einen neuen       Palyazofarbstoff    erhält,     %venn    man 1     141o1          diazotiertes        1-Amino    - 2 -     oxy-    5 -     chlorbenzol,     1     31o1        2-Amino-5-oxynaphthalin-7-sulfon-          säure,    1     Mol        Cyanurchlorid,    1     Mol        4-Amino-          4'-oxy-1,

  1'-azobenzol-3'-carbonsäure    und  1     11o1    Anilin derart aufeinander einwirken  lässt, dass die     Diazoverbindung    in     6-Stellung     der     Aminooxynaphthalinsulfonsäure    eingreift  und die drei Halogenatome des     Cyanur-          ehlorids    sich jeweils mit der     Aminogruppe          cler        Aminooxynaphthalinsulfonsäure,    der       Aminooxyazobenzolcarbonsä-ure    und des Ani  lins umsetzen.  



  Der neue Farbstoff stellt ein dunkel  braunes     Pulver    dar, das aus einem Färbe  bade, welches mit Kupfersulfat und wein  saurem Natrium versetzt wurde, Baumwolle  in rotbraunen Tönen von guter Licht- und  Waschechtheit anfärbt.    30%iger Salzsäure gelöst. Die     Lösung    wird  auf 0  gekühlt und mit 6,9 Teilen Natrium  nitrit in 25 Teilen Wasser     diazotiert.    Inzwi  schen werden 66,4     Teile    des auf bekannte  Weise dargestellten     ternären    Kondensations  produktes aus je 1     1V101        Cyanurchlorid.     2 -     Amino    - 5 -     oxynaphthalin    - 7 -     sulfonsäure,

Die  Lösung wird mit Eis auf 10  gekühlt und  mit der     Diazoniumlösung    versetzt. Man rührt  die Kupplung so lange, bis sich keine     Di-          azoniumverbindung    mehr nachweisen lässt.  Dann erwärmt. man auf 80 , salzt den gebil  deten Farbstoff aus, filtriert und trocknet.



  Process for the preparation of a polyazo dye. Additional patent to main patent no. 240225. It has been found that a new palyazo dye is obtained if 1 141o1 diazotized 1-amino-2-oxy-5-chlorobenzene, 1 31o1 2-amino-5 -oxynaphthalene-7-sulfonic acid, 1 mol of cyanuric chloride, 1 mol of 4-amino-4'-oxy-1,

  1'-azobenzene-3'-carboxylic acid and 1 11o1 aniline can act on one another in such a way that the diazo compound engages in the 6-position of the aminooxynaphthalenesulfonic acid and the three halogen atoms of the cyanuric chloride each correspond to the amino group of the aminooxynaphthalenesulfonic acid and the aminooxyazobenzenecarboxylic acid Implement anilins.



  The new dye is a dark brown powder that bathes from a dye that has been mixed with copper sulfate and acidic sodium, and dyes cotton in red-brown shades of good light and wash fastness. Dissolved 30% hydrochloric acid. The solution is cooled to 0 and diazotized with 6.9 parts of sodium nitrite in 25 parts of water. In the meantime, 66.4 parts of the ternary condensation product, prepared in a known manner, each consist of 1V101 of cyanuric chloride. 2 - amino - 5 - oxynaphthalene - 7 - sulfonic acid,

            4-Amino-4'-oxy-1,1'-azobenzene-3'-carboxylic acid and aniline dissolved in 1600 parts of water and 30 parts of sodium carbonate at 50%. The solution is cooled to 10 with ice and the diazonium solution is added. The coupling is stirred until no more diazonium compounds can be detected. Then warmed up. it is increased to 80, the dye formed is salted out, filtered and dried.
