Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass ein neuer     Azo-          farbstoff    hergestellt werden kann, wenn man       diazotiertes        1-Amino-2-methoxy-4-nitroben-          zol    mit     2,3-Oxynaphthoesäure-3'-pyrenolid     vereinigt.  



  Der neue     Azofarbstoff    bildet ein violet  tes, in Wasser unlösliches Pulver. Auf ge  eigneten Substraten, wie z. B. Baumwolle,  hergestellt, färbt er diese in sehr echten, ins  besondere auch lichtechten violetten Tönen.         Beispiel:

       16,8 Teile     1-Amino-2-methoxy-4-nitro-          benzol        ('/1o        Mol)    werden wie üblich     diazo-          tiert    und in eine Lösung von 38,8 Teilen       2,3-Oxynaphthoesäure-3'-pyrenolid        ('/1o        Mol),     100 Teilen     Natriumhydrogydlösung    von  36       B6,    15 Teilen     Natriumacetat        und       2000 Teilen Wasser eingetragen. Der gebil  dete Farbstoff fällt sofort aus.

   Er     wird    ab  filtriert,     mit    Wasser gewaschen und ge  trocknet.



  Process for the production of a new azo dye. It has been found that a new azo dye can be produced if diazotized 1-amino-2-methoxy-4-nitrobenzene is combined with 2,3-oxynaphthoic acid-3'-pyrenolide.



  The new azo dye forms a purple powder that is insoluble in water. On ge suitable substrates such. B. Cotton, produced, he dyes them in very real, especially lightfast purple tones. Example:

       16.8 parts of 1-amino-2-methoxy-4-nitrobenzene (1/10 mol) are diazotized as usual and dissolved in a solution of 38.8 parts of 2,3-oxynaphthoic acid-3'-pyrenolide / 10 mol), 100 parts of sodium hydrogen solution of 36 B6, 15 parts of sodium acetate and 2000 parts of water. The formed dye precipitates immediately.

   It is filtered off, washed with water and dried ge.
