Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoifes.       Es wurde gefunden, dass man einen wert  vollen neuen     Azofarbstoff    erhält, wenn man  das     Arylid    aus     2.3-Oxynaphthoesäure    und       a-Naphthylamin    mit     diazotiertem        1-Amino-          2    -     methoxv    - 4 -     benzoylamino    - 5 -     chlorbenzol     vereinigt.  



  Der neue     Farbstoff,    auf der Faser her  gestellt, färbt dieselbe in echten     violett-          stichigen    roten Tönen.  



  <I>Beispiel:</I>  27,6 Teile     1-Amino-2-methoxy-4-benzoyl-          amino-5-chlorbenzol    werden wie üblich diano  tiert und in eine Lösung von 31,3 Teilen des       Arylides    aus 2. 3 -     Oxynaphthoesäure    und       a-Naphthylamin,    90 Teilen 30 %     ige    Natron  lauge, 100 Teilen Soda und 2000 Teilen    Wasser eingetragen. Der gebildete Farbstoff  fällt sofort aus. Der bordeauxrote Niederschlag  wird filtriert und getrocknet.



  Process for the production of a new azo dye. It has been found that a valuable new azo dye is obtained if the arylide of 2,3-oxynaphthoic acid and α-naphthylamine is combined with diazotized 1-amino-2-methoxy-4-benzoylamino-5-chlorobenzene.



  The new dye, produced on the fiber, dyes it in real purple-tinged red tones.



  <I> Example: </I> 27.6 parts of 1-amino-2-methoxy-4-benzoylamino-5-chlorobenzene are dianoed as usual and added to a solution of 31.3 parts of the arylide from 2. 3 - Oxynaphthoic acid and a-naphthylamine, 90 parts of 30% sodium hydroxide, 100 parts of soda and 2000 parts of water entered. The dye formed precipitates immediately. The burgundy precipitate is filtered and dried.
