      Zusatzpatent    zum Hauptpatent Nr. 217241.    Verfahren zur Herstellung eines neuen     Azofar        bstoffes.       Es wurde gefunden,     :dass    man einen neuen       Azofarbstoff    erhält, wenn man 1     Mol        Cyanur-          chlo:rid,    1     Mol        des        Produktes,    das erhalten  wird     :dumch        Reduzieren    :

  des     Acylierungspro-          duktes    aus 1     Mol        1-Amino-4-(4'-amino-3'-          sulfo)-anilidoanthrachinon-2-sulfonsäure    und  1-     Mol    m -     Nitrobenzoylchlorid,    1     Mol          4-Amino-4'-oxy-1,1'-azobenzol-3'-ca.rbonsäure          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 al  kalischem Bade in Gegenwart von Kupfer  sulfat und weinsaurem Natrium in wasch  und     lichteehten    grünen Tönen färbt.  



  <I>Beispiel:</I>  48;9     Gewichtsteile        1-Amino-4-(4'-amino-3'-          sulfo)-anili:doanth.ra,chinon-2-sulfonsäure    wer  den als     Dinatriumealz    in 500 Gewichtsteilen  Wasser     unter    Zusatz von 8,4 Gewichtsteilen       Natriumbicarbo.nat    gelöst. Diese Lösung wird  bei. zirka. 60   mit 18;5     Gewichtsteilen            in-Nitroben:zoylchlorid,    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     60-7,0'    zum ent  sprechenden     Aminobenzoylpro:dukt.    60,8 Ge  wichtsteile .des     abgesehie:

  denen    Reduktions  produktes werden als neutrale     Lösung    in  1000     Gewichtsteilen    Wasser zu einer An  sühlämmung von 18,5     Gewichtsteilen        Cyanur-          chlorid    in 500     Gewichtsteilen    kaltem Wasser  gegeben. Man hält :die Temperatur 1 Stunde  bei 10-15  . Die bei :der Kondensation ent  stehende Salzsäure wird durch     .die    e t  ;spreehen.de Menge     Natriumcarbonat    neutrali  siert.

   Hernach werden 25,7 Gewichtsteile       4-Amino    -     4'-oxy-1,1'-azobenzol-3'-:carbonsäure     in 1,000     Gewichtsteilen    warmem     Wasser    ge  löst, zum     Monokondensationsprodukt        ge-          eben.    Die Temperatur wird dabei auf 40    erhöht. Nach 48 Stunden .gibt man<B>18</B> Ge  wichtsteile Anilin zu und hält die Tempera-           tur        während        rl@r    bleichen     Zeit    auf 80<B>'</B>.

   Das  tertiäre     Kondensationsprodukt    ist nach     dieser     Zeit     o;ebil.det.   <B>Es</B> wird mit.     Natriumehlorid          abgeschieden    und getrocknet.



      Additional patent to the main patent no. 217241. Process for the production of a new azo dye. It has been found that: a new azo dye is obtained if 1 mole of cyanuric chloride, 1 mole of the product that is obtained: by reducing:

  of the acylation product from 1 mol of 1-amino-4- (4'-amino-3'-sulfo) -anilidoanthraquinone-2-sulfonic acid and 1 mol of m-nitrobenzoyl chloride, 1 mol of 4-amino-4'-oxy-1 , 1'-azobenzene-3'-carboxylic acid and 1st mole of aniline can act on one another.

   The new dye is a: dark powder: which dissolves in water with a green color and dyes cotton in a weakly alkaline bath in the presence of copper sulfate and tartrate of sodium in washed and light green tones.



  <I> Example: </I> 48; 9 parts by weight of 1-amino-4- (4'-amino-3'-sulfo) -anili: doanth.ra, quinone-2-sulfonic acid are used as disodium salts in 500 parts by weight of water dissolved with the addition of 8.4 parts by weight of sodium bicarbonate. This solution is at. about. 60 with 18; 5 parts by weight of in-nitrobene: zoyl chloride to which 10 parts by weight of acetone were 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 60-7.0 'to the corresponding aminobenzoyl product. 60.8 parts by weight of the following:

  which reduction product are added as a neutral solution in 1000 parts by weight of water to a sühlämmung of 18.5 parts by weight of cyanuric chloride in 500 parts by weight of cold water. Maintain: the temperature for 1 hour at 10-15. The hydrochloric acid formed during the condensation is neutralized by the amount of sodium carbonate.

   Thereafter, 25.7 parts by weight of 4-amino-4'-oxy-1,1'-azobenzene-3 '-: carboxylic acid are dissolved in 1,000 parts by weight of warm water to form the monocondensation product. The temperature is increased to 40. After 48 hours, <B> 18 </B> parts by weight of aniline are added and the temperature is kept at 80 <B> '</B> for a bleaching time.

   The tertiary condensation product is o; ebil.det after this time. <B> It </B> comes with. Sodium chloride deposited and dried.
