Description

  

      Zusatzpatent    zum Hauptpatent Nr. 152881.         Verfahren    zur Herstellung eines neuen     Azofarbstofies.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, welcher der Formel:  
EMI0001.0004     
    entspricht, wenn man dianotiertes     Phenoxy-          acetylamino-2.5-dimethyl-l-aminobenzol    mit  dem     2-Methyl-4-methoxyanilid    der 2.     3-Oxy-          naphthoesäure    kuppelt.  



  Der neue Farbstoff bildet ein dunkel  rotes Pulver. Auf geeigneten     Substraten,     wie zum Beispiel pflanzlichen Fasern, her  gestellt, färbt er diese in echten blauroten  Tönen.    <I>Beispiel:</I>  27 Teile     Phenoxyacetylamino-2.5-di-          methyl-l-aminobenzol    werden wie üblich di-         azotiert    und in eine Lösung von 30,7 Teilen  des     2-Methyl-4-methoxyanilids    der 2 .     3-Oxy-          naphthoesäure,    50 Teilen 30     o/oiger    Natron  lauge, 30 Teilen Soda und 2000 Teilen       Wasser    eingetragen. Der gebildete Farbstoff  fällt sofort aus.

   Der dunkelrote Niederschlag  wird filtriert und getrocknet.



      Additional patent to main patent No. 152881. Process for the production of a new azo dye. It has been found that a new dye is obtained which has the formula:
EMI0001.0004
    corresponds if one couples dianotated phenoxyacetylamino-2,5-dimethyl-1-aminobenzene with the 2-methyl-4-methoxyanilide of the 2. 3-oxynaphthoic acid.



  The new dye forms a dark red powder. Produced on suitable substrates such as vegetable fibers, he dyes them in real blue-red tones. <I> Example: </I> 27 parts of phenoxyacetylamino-2,5-dimethyl-1-aminobenzene are azotized as usual and dissolved in a solution of 30.7 parts of the 2-methyl-4-methoxyanilide of the 2. Entered 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 red precipitate is filtered and dried.
