  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden,     @class    man .einen neuen       Azofarbstoff    erhält, wenn in-an auf     Cyanur-          chlorid    1     Mol    des reduzierten     Aeylierungs-          produktes,    das erhalten wird durch Reduzie  ren des     Acylierungsproduktes    aus     1-Amino-          4-        (4'-amino-    3'-     sulf    o)

   -     anilidoanthrachinon-2-          sulfonsäure    und     p-Nitrobenzoylchlorid,    1     Mol     4     -Amino        -4'-ogy-1,1'-@azob        enzol-3'-carbons        äure     und 1     Mol    Anilin 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 Kupfersulfat und weinsaurem  Natrium in wasch- und lichtechten grünen  Tönen färbt.  



       Beispiel:     48,9     Gewichtsteile        1-Amino-4-(4'-amino-          3'-sulfo)        -anilidoanthrmhinon-2-sulfonsäure     werden als     Dinatriumsalz    in 500 Gewichts  teilen Wasser     unter        Zusatz    von 8,4 Gewichts  teilen     Natriumbicarbonat    gelöst. Diese Lö  sung wird bei ca. 60<B>'</B>mit 18,5 Gewichtsteilen       9.-Nitrobenzoylchlori,d,    die mit 10 Gewichts-         teilen    Aceton versetzt wurden, behandelt.

    Man reduziert das,     entstandene        Nitrobenzoyl-          produkt        mit    42     Gewichtsteilen    kristallisier  tem     Natriumsulfid,    die     in    100 Gewichtsteilen       Wasser    gelöst wurden, bei 60 bis<B>70'</B> zum       entsprechenden        Aminobenzoylprodukt.    60,8       Gewichtsteile    des.

   abgeschiedenen     ReduktiGns-          pro,duktes    werden als neutrale Lösung in  1000     Gewichtsteilen    Wasser zu     einer        An-          schlämmung    von 18,5 Gewichtsteilen     Cyanur-          chlorid    in 500     Gewichtsteilen        kaltem    Wasser  gegeben. Man hält die Temperatur eine       Stunde    bei 10 bis 15  . Die bei der Kondensa  tion     entstehende        Salzsäure    wird durch die  entsprechende Menge     Natriumcarbonat    neu  tralisiert.

   Hernach werden 25,7 Gewichts  teile     4-Amino-4'-ogy-1,1'-azobenzol-3'-carban-          säure,    in 500     Gewichtsteilen    warmem Wasser  gelöst, zum     Monokondensationsprodukt    ge  geben. Die     Temperatur        wird    dabei auf 40'  erhöht. Nach 48 Stunden gibt man 18 Ge  wichtsteile     Anilin    zu und hält die Tempera  tur während ,der gleichen Zeit auf<B>80'.</B> Das           tertiäre        Kondensationsprodukt    ist nach dieser  Zeit gebildet. Es wird mit     Natriumehlorid     abgeschieden und     getrocknet.  



  Process for the production of a new azo dye. It has been found that a new azo dye is obtained when 1 mol of the reduced aylation product obtained by reducing the acylation product from 1-amino-4- (4'-amino- 3'-sulf o)

   - Anilidoanthraquinone-2-sulfonic acid and p-nitrobenzoyl chloride, 1 mol of 4-amino -4'-ogy-1,1 '- @ azobenzene-3'-carboxylic acid and 1 mol of aniline can act. 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.



       Example: 48.9 parts by weight of 1-amino-4- (4'-amino-3'-sulfo) -anilidoanthrmhinone-2-sulfonic acid are dissolved as the disodium salt in 500 parts by weight of water with the addition of 8.4 parts by weight of sodium bicarbonate. This solution is treated at approx. 60 with 18.5 parts by weight of 9-nitrobenzoylchloride, to which 10 parts by weight of acetone have been added.

    The resulting nitrobenzoyl product is reduced with 42 parts by weight of crystallized sodium sulfide, which were dissolved in 100 parts by weight of water, at 60 to 70 'to the corresponding aminobenzoyl product. 60.8 parts by weight of the.

   Separated reducing products are added as a neutral solution in 1000 parts by weight of water to a suspension of 18.5 parts by weight of cyanuric chloride in 500 parts by weight of cold water. The temperature is kept at 10 to 15 for one hour. The hydrochloric acid formed during the condensation is neutralized with the appropriate amount of sodium carbonate.

   Thereafter, 25.7 parts by weight of 4-amino-4'-ogy-1,1'-azobenzene-3'-carbanic acid, dissolved in 500 parts by weight of warm water, are added to the monocondensation product. The temperature is increased to 40 '. After 48 hours, 18 parts by weight of aniline are added and the temperature is maintained at <B> 80 'for the same time. </B> The tertiary condensation product is formed after this time. It is deposited with sodium chloride and dried.
