Description

  

      Ziicatzpatent    zum Hauptpatent Nr. 167173.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen     Azofarbstoff    der Formel  
EMI0001.0004     
    erhält, wenn man den     Äthylester    der     1-Diazo-          5-chlor-2-benzolcarbonsäure    mit dem     Tereph-          thaloyl-bis-(essigsäure-p-anisidid)    kuppelt.  



  Der so erhaltene Farbstoff stellt ein gelb  oranges Pulver dar. Auf geeigneten Substraten,  wie zum Beispiel Baumwolle, Wolle, Kunst  seide, hergestellt, färbt er diese in leuchten  den echten gelben Tönen.    <I>Beispiel:</I>  39,9 Teile     Äthylester    der     1-Amino-5-chlor-          2-benzolcarbonsäure    werden wie üblich     dia-          zotiert    und in eine Lösung von 42,8 Teilen       Terephthaloyl    - bis -     (essigsäure    - p -     anisidid),     100 Teilen     Natriumhydrogydlösung    (30     ojoig),     15 Teilen Soda und 2000 Teilen Wasser ein  getragen.

   Der gebildete Farbstoff fällt sofort  aus. Er wird filtriert, gewaschen und getrocknet.



      Ziicatzpatent for main patent no. 167173. Process for the production of a new azo dye. It has been found that a new azo dye of the formula
EMI0001.0004
    obtained when the ethyl ester of 1-diazo-5-chloro-2-benzenecarboxylic acid is coupled with terephthaloyl bis (acetic acid p-anisidide).



  The dye obtained in this way is a yellow-orange powder. Produced on suitable substrates, such as cotton, wool, artificial silk, it dyes these in shining real yellow tones. <I> Example: </I> 39.9 parts of the ethyl ester of 1-amino-5-chloro-2-benzenecarboxylic acid are diazotized as usual and converted into a solution of 42.8 parts of terephthaloyl - bis - (acetic acid - p - anisidide), 100 parts of sodium hydrogen solution (30 ojoig), 15 parts of soda and 2000 parts of water.

   The dye formed precipitates immediately. It is filtered, washed and dried.
