Description

  

      Verfahren        zur    Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Farbstoff    erhält, welcher der Formel:  
EMI0001.0005     
    entspricht, wenn man dianotiertes     4-(1'-          Methyl)-phenoxyacetylamino    -2 . 5-     dimethoxy-          1-aminobenzol    mit dem     p-Anisidid    der 2 .     3-          Oxynaphthoesäure    kuppelt.  



  Der neue     Farbstoff    bildet ein dunkel  violettes Pulver. Auf geeigneten Substraten,  wie zum Beispiel pflanzlichen Fasern, herge  stellt, färbt er diese in echten violetten Tönen.  <I>Beispiel:</I>  31,6 Teile     4-(1'-Methyl)-phenoxyacetyl-          amino-2.5-dimetboxy-l-aminobenzol    werden  wie üblich dianotiert und in eine Lösung von  29,3 Teilen des     p-Anisidids    der 2 .     3-Oxynaph-          thoesäure,    50 Teilen 30     o/oiger    Natronlauge,  30 Teilen Soda. und 2000 Teilen Wasser ein-    getragen. Der gebildete Farbstoff fällt sofort  aus. Der dunkelviolette Niederschlag wird  filtriert und getrocknet.



      Process for the production of a new azo dye. It has been found that a new dye is obtained which has the formula:
EMI0001.0005
    corresponds if one dianotated 4- (1'-methyl) -phenoxyacetylamino -2. 5- dimethoxy-1-aminobenzene with the p-anisidide of the 2nd 3- oxynaphthoic acid couples.



  The new dye forms a dark purple powder. On suitable substrates, such as vegetable fibers, he dyes them in real purple tones. <I> Example: </I> 31.6 parts of 4- (1'-methyl) -phenoxyacetyl-amino-2.5-dimetboxy-1-aminobenzene are dianotized as usual and in a solution of 29.3 parts of the p-anisidide the second . 3-oxynaphthoic acid, 50 parts of 30% sodium hydroxide solution, 30 parts of soda. and 2000 parts of water entered. The dye formed precipitates immediately. The dark purple precipitate is filtered and dried.
