Description

  

      Zusatzpatent    zum     Hauptpatent    Nr. 203426.    Verfahren zur Herstellung eines     Polyazofarbstoffes.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung     eines        Polyazo-          farbstoffes.    Das Verfahren ist dadurch ge-    kennzeichnet, dass man den nach dem 'Ver  fahren der     schweiz.    Patentschrift Nr.

   190894  erhältlichen     Disazofarbstoff    der Konstitution  
EMI0001.0009     
         diazotiert,    mit dein Kondensationsprodukt aus  m - Ami     nophenyl    - 5 -     pyrazolon    - 3     -carbonsäure     und dein Chlorid des     4-Carboxy-2-nitrophenyl-          ätliylsulfons    kuppelt und die Nitrogruppe zur       Aminogruppe    reduziert. Der neue Farbstoff  stellt ein hellbraunes Pulver dar, das Baum  wolle nach dem     Diazotieren    und Entwickeln  mit     ss-Naphthol    in gelben Tönen färbt.  



  <I>Beispiel:</I>  219 Teile     1-(3'-Aminophenyl)-5-pyrazolon-          3-carbonsäure    in 800 Teilen     Pyridin    gelöst    werden     portionsweise    mit<B>555</B> Teilen des  Chlorids aus     4-Carboxy-2-nitrophenyl-äthyl-          sulfon    versetzt. Nach längerem Stehen wird  das abgekühlte, feste Reaktionsprodukt mit  Wasser verrührt, das abgeschiedene Konden  sationsprodukt isoliert. Es löst sich mit Soda  in Wasser klar auf und lässt sich nicht mehr       diazotieren.     



  46 Teile des so erhältlichen Kondensa  tionsproduktes werden in Wasser gelöst, mit  30 Teilen Soda vermischt und mit der     Di-          azoverbindung    aus 65 Teilen des Körpers    
EMI0002.0001     
    die nach dein D. R. P. 632135 zugängig ist,  vereinigt. Der Farbstoff wird nach vollendeter  Kupplung auf<B>800</B> erwärmt und mit 42 Tei  len Schwefelnatrium kristallisiert in Wasser  reduziert, nach beendigter Reduktion     ausge-          salzen,    gepresst und getrocknet. Er färbt auf  Baumwolle nach dein     Diazotieren    und Ent  wickeln mit     P-Naphthol    ein Gelb.



      Additional patent to main patent no. 203426. Process for the production of a polyazo dye. The present patent relates to a process for the production of a polyazo dye. The procedure is characterized by the fact that the procedure of Switzerland is used. Patent No.

   190894 available disazo dye of the constitution
EMI0001.0009
         diazotized, with your condensation product of m - Ami nophenyl - 5 - pyrazolone - 3 -carboxylic acid and your chloride of 4-carboxy-2-nitrophenyl ätliylsulfons coupled and reduced the nitro group to the amino group. The new dye is a light brown powder which, after diazotizing and developing with ss-naphthol, dyes the cotton in yellow tones.



  <I> Example: </I> 219 parts of 1- (3'-aminophenyl) -5-pyrazolone-3-carboxylic acid are dissolved in 800 parts of pyridine in portions with <B> 555 </B> parts of the chloride from 4-carboxy -2-nitrophenyl-ethyl sulfone added. After standing for a long time, the cooled, solid reaction product is stirred with water, and the precipitated condensation product is isolated. It dissolves clear in water with soda and can no longer be diazotized.



  46 parts of the condensation product obtainable in this way are dissolved in water, mixed with 30 parts of soda and with the di-azo compound from 65 parts of the body
EMI0002.0001
    which is accessible according to your D. R. P. 632135, united. After coupling is complete, the dye is heated to 800 and reduced with 42 parts of sodium sulphide, crystallized in water, then salted out, pressed and dried after the reduction is complete. After diazotizing and developing with p-naphthol, it dyes cotton a yellow.
