Description

  

  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-          2-benzolcarbonsäure    mit dem     Tereplrthaloyl-          bis-(essigsäure-2-methoxy    - 5 -     methylanilid)     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 leuch  tenden sehr echten     grünstichiggelben    Tönen.    <I>Beispiel:</I>  33 Teile     Äthylester    der     1-Amino-2-benzol-          carbonsäure    werden wie üblich     diazotiert    und  in eine Lösung von 45,6 Teilen     Teraph-          thaloyl    - bis -     (essigsäure-2-methogy-5-methyl-          anilid),    100 Teilen     Natriumhydroxydlösung     (30     o/oig),

      15 Teilen Soda und 2000 Teilen  Wasser eingetragen. Der gebildete     Farbstoff     fällt sofort aus. Er wird filtriert, gewaschen  und getrocknet.



  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-2-benzenecarboxylic acid is coupled with the terephthaloyl bis (acetic acid 2-methoxy - 5 - methylanilide).



  The dye obtained in this way is a yellow-orange powder. Produced on suitable substrates, such as cotton, wool, artificial silk, it dyes them in bright, very genuine greenish-yellow tones. <I> Example: </I> 33 parts of ethyl ester of 1-amino-2-benzene-carboxylic acid are diazotized as usual and converted into a solution of 45.6 parts of teraphthaloyl - bis - (acetic acid-2-methogy-5- methyl anilide), 100 parts of sodium hydroxide solution (30%),

      15 parts of soda and 2000 parts of water entered. The dye formed precipitates immediately. It is filtered, washed and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines Azofarbstoffes der Formel EMI0002.0002 dadurch gekennzeichnet, dass man den Äthyl ester der 1-Diazo-2-benzolcarbonsäure mit dem Terephthaloyl-bis-(essigsäure-2-methogy- 5-methylanilid) kuppelt. Der so erhaltene Farbstoff stellt ein gelb oranges Pulver dar. Auf geeigneten Sub- straten, wie zum Beispiel Baumwolle, Wolle, Kunstseide, hergestellt, färbt er diese in leuchtenden sehr echten grünstichiggelben Tönen. PATENT CLAIM: Process for the preparation of an azo dye of the formula EMI0002.0002 characterized in that the ethyl ester of 1-diazo-2-benzenecarboxylic acid is coupled with terephthaloyl-bis (acetic acid-2-methogy-5-methylanilide). The dye obtained in this way is a yellow-orange powder. Produced on suitable substrates such as cotton, wool, rayon, it dyes them in brilliant, very genuine greenish-yellow tones.
