Description

  

  Verfahren zur     Herstellung    eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man dianotiertes       2-Amino-1,4-diäthoxyacridon    der Formel  
EMI0001.0005     
         (Numerierung    nach     Ullmann,    Annalen 355,  Seite 312-371) mit dem     Anilid    der     2.3-          Oxynaphthoesäure    vereinigt. Der so erhaltene       Farbstoff    bildet ein blauviolettes Pulver. Auf  geeigneten Substraten, wie z. B.

   Baumwolle,  hergestellt, färbt er diese in blauen Tönen  von vorzüglichen     Eehtheitseigenschaften.     



  <I>Beispiel:</I>  31,8 Teile des     2-Amino-1,4-diäthoxyacri-          dons    der Formel  
EMI0001.0015     
         (Numerierung    nach     Ullmann,    Annalen 355,  Seite 312-371) werden wie üblich diano  tiert und in eine Lösung von 26,3 Teilen  2.     3-Oxynaphthoesäureanilid,    50 Teilen 30  /o  iger     Natriumhydroxydlösung,    15 Teilen Na  triumkarbonat und 2000 Teilen Wasser ein  getragen. Der gebildete     Farbstoff    fällt sofort  aus. Der blauviolette Niederschlag wird fil  triert und getrocknet.



  Process for the production of a new azo dye. It has been found that a new azo dye is obtained if dianotated 2-amino-1,4-diethoxyacridone of the formula
EMI0001.0005
         (Numbering according to Ullmann, Annalen 355, pages 312-371) combined with the anilide of 2,3-oxynaphthoic acid. The dye thus obtained forms a blue-violet powder. On suitable substrates, such as. B.

   Cotton, produced, he dyes them in blue tones of excellent fastness properties.



  <I> Example: </I> 31.8 parts of the 2-amino-1,4-diethoxyacridone of the formula
EMI0001.0015
         (Numbering according to Ullmann, Annalen 355, pages 312-371) are diano benefits as usual and in a solution of 26.3 parts of 2. 3-oxynaphthoic anilide, 50 parts of 30% sodium hydroxide solution, 15 parts of sodium carbonate and 2000 parts of water carried. The dye formed precipitates immediately. The blue-violet precipitate is filtered off and dried.
