Description

  

      Verfahren    zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden,     da.ss    man einen neuen     .Azofarbstoff    der Formel  
EMI0001.0005     
    erhält, wenn man den     2-Diazo-5-acetylamino-          4.    4' -     dichlor    - 1 . 1' -     diphenyläther    mit dem       2-Methoxyanilid    .der 2.     3-Oxynaphthoesäure     kuppelt.  



  Der so erhaltene Farbstoff bildet ein  bordeauxrotes Pulver. Auf geeigneten Sub  straten, wie zum Beispiel Baumwolle, Wolle,  Kunstseide, hergestellt, färbt er diese in  leuchtenden, sehr echten bordeauxroten Tönen.    <I>Beispiel:</I>  31,1 Teile     2-Amino-5-acetylamino-4.4'-          dichlor-1.        1'-diphenyläther    werden     wie    üblich       diazotiert    und in eine Lösung von 29,3 Tei  len des     2-Methoxyanilids    der 2.     3-Oxynaph-          thoesäure,    60 Teilen 30%iger Natrium  hydroxydlösung, 15 Teilen     krist.    Natrium  acetat und 20:00 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
EMI0001.0005
    obtained when the 2-diazo-5-acetylamino-4. 4 '- dichloro - 1. 1 '- diphenyl ether with the 2-methoxyanilide, which couples the 2nd 3-oxynaphthoic acid.



  The dye obtained in this way forms a burgundy powder. Manufactured on suitable substrates, such as cotton, wool, rayon, for example, he dyes them in bright, very genuine burgundy shades. <I> Example: </I> 31.1 parts of 2-amino-5-acetylamino-4,4'-dichloro-1. 1'-diphenyl ether are diazotized as usual and crystallized in a solution of 29.3 parts of 2-methoxyanilide of the 2nd 3-oxynaphthoic acid, 60 parts of 30% sodium hydroxide solution, 15 parts. Sodium acetate and 20:00 parts of water entered.

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