Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Farbstoff    erhält, welcher der Formel:  
EMI0001.0003     
    entspricht; wenn man dianotiertes 4-(1'  Methyl)-phenogyacetylamino -2 . 5-     dimethoxy-          1-aminobenzot    mit dem     m-Xylidid    der     2.3-          Oxynaphthoesäure    kuppelt.  



  Der neue Farbstoff bildet ein dunkel  violette. 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-dimethoxy-l-aininobenzol    werden  wie üblich dianotiert und in eine Lösung von  29,1 Teilen des     m-Xylidids    der     2.3-Oxy-          naphthoesäure,    50 Teilen 30      /oiger    Natron-    lauge, 30 Teilen Soda und 2000 Teilen  Wasser eingetragen. Der gebildete     Farbstoff     fällt sofort aus. Der dunkelviolette Nieder  schlag 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:
EMI0001.0003
    corresponds to; if you dianotated 4- (1 'methyl) -phenogyacetylamino -2. 5- dimethoxy- 1-aminobenzot couples with the m-xylidide of 2,3-oxynaphthoic acid.



  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-dimethoxy-1-aininobenzene are dianotized as usual and in a solution of 29.1 parts of the m-xylidide of 2,3-oxynaphthoic acid, 50 parts of 30% sodium hydroxide solution, 30 parts of soda and 2000 parts of water. The dye formed precipitates immediately. The dark purple precipitate is filtered and dried.
