  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 217241.    Verfahren zur Herstellung eines neuen     AzofarbstofFes.       Es wurde gefunden,     dass    man einen  neuen     Azofarbstoff    erhält, wenn man 1     Mol          Cyanurchlorid,    1     Mol    der     1-Amino-4-(4'-          amino-        3'-sulf        o)-anilidoanthrachinon-2-sulf        on-          säure,    1     Mol    des     Produktes,

      das erhalten  wird     durch        Reduzieren    .des     A.cylierungs-          produktes    aus 1     Mol        meta-Nitrobenzoylchlo-          rid    und 1     Mol        4-Amino-4'-ogy-1,1'-azobenzol-          3'-carbonsäure    und 1     Mol        Anilin    aufeinander  einwirken lässt.

   Der neue Farbstoff stellt ein       dunkles    Pulver .dar, das sich in Wasser mit  grüner Farbe löst und Baumwolle in schwach  alkalischem Bade in Gegenwart von Kupfer  sulfat und weinsaurem Natrium in     wasch-          und    lichtechten grünen Tönen färbt.

      <I>Beispiel:</I>  48,'9 Gewichtsteile     1-Amino-4-(4'-amino-          3'    -     sulfo)    -     anilidoanthraehinon    -'2     -sulfonsäure     werden als neutrale Lösung in 1000     Ge-          wichtsteilen    Wasser zu einer     Anschlämmung     von 18.5 Gewichtsteilen     Cyanurchlorid    in  500 Gewichtsteilen kaltem     Wasser        gegeben.       Man hält die Temperatur 4     ,Stunden    bei 10  bis 15  .

   Die bei der     Kondensation    ent  stehende     Salzsäure        wird    durch die entspre  chende Menge     Natriumcarbonat        neutralisiert.     Hernach werden 37;

  6     Gewichtsteile        Jes    Pro  duktes, das erhalten wird durch Reduzieren  des     Acylierungsproduktes        aus        meta-Nitro-          benzoylchlorid    und     4-Amino-4'-ogy-1,1'-azo-          benzol-,3'-carbonsäure    in 50,0 Gewichtsteilen  warmem     Wasser    gelöst, zum     Monokondeiuea-          tionsprodukt    .gegeben. Die Temperatur     wird     dabei auf 40   erhöht.

   Nach 24     Stunden    .gibt       man    18 Gewichtsteile     Anilin    zu und hält die  Temperatur während der     ,gleichen    Zeit auf  80  . Das     tertiäre        Kondensationsprodukt        ist     nach dieser Zeit     .gebildet,    Es wird mit     Na-          triumehlorid        abgeschieden    und getrocknet.



  <B> Additional patent </B> to main patent no. 217241. Process for the production of a new azo dye. It has been found that a new azo dye is obtained when 1 mole of cyanuric chloride, 1 mole of 1-amino-4- (4'-amino-3'-sulfo) -anilidoanthraquinone-2-sulfonic acid, 1 mole of the product,

      this is obtained by reducing the acylation product from 1 mole of meta-nitrobenzoyl chloride and 1 mole of 4-amino-4'-ogy-1,1'-azobenzene-3'-carboxylic acid and 1 mole of aniline .

   The new dye is a dark powder that dissolves in water with a green color and colors cotton in a weakly alkaline bath in the presence of copper sulfate and tartrate of sodium in washable and lightfast green tones.

      <I> Example: </I> 48, '9 parts by weight of 1-amino-4- (4'-amino-3' - sulfo) - anilidoanthraehinone -'2 -sulfonic acid become a neutral solution in 1000 parts by weight of water Added suspension of 18.5 parts by weight of cyanuric chloride in 500 parts by weight of cold water. The temperature is maintained at 10 to 15 hours for 4 hours.

   The hydrochloric acid formed during the condensation is neutralized by the appropriate amount of sodium carbonate. Afterwards 37;

  6 parts by weight of Jes Pro products, which is obtained by reducing the acylation product from meta-nitrobenzoyl chloride and 4-amino-4'-ogy-1,1'-azo-benzene, 3'-carboxylic acid in 50.0 parts by weight of warm water dissolved, given to the monoconduction product. The temperature is increased to 40.

   After 24 hours, 18 parts by weight of aniline are added and the temperature is maintained at 80 for the same time. The tertiary condensation product is formed after this time. It is deposited with sodium chloride and dried.
