Description

  

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



  Der neue     Azofarbstoff    bildet ein rot  braunes, in Wasser unlösliches Pulver. Auf  geeigneten Substraten,     wie    z. B. Baumwolle,  hergestellt, färbt er diese in sehr echten,  insbesondere auch lichtechten, rotbraunen  Tönen.  



  <I>Beispiel:</I>  12,7 Teile     1-Amino-3-ehlorbenzol        (1%io        Mol)     werden wie üblich     diazotiert    und in eine  Lösung von 38,8 Teilen     2,3-Oxynaphthoe-          säure-3'-pyrenolid        (1/1o        Mol),    100 Teilen Na  triumhydroxydlösung von 36 o     B6,    15 Teilen       Natriumacetat    und 2000 Teilen Wasser ein-    getragen. Der gebildete Farbstoff fällt so  fort aus. Er wird     abfiltriert,    mit Wasser ge  waschen und getrocknet.



  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-3-chlorobenzene is combined with 2,3-oxynaphthoic acid-3'-pyrenolide.



  The new azo dye forms a red-brown powder that is insoluble in water. On suitable substrates, such as. B. cotton, produced, he dyes them in very real, especially lightfast, red-brown tones.



  <I> Example: </I> 12.7 parts of 1-amino-3-chlorobenzene (1% 10 mol) are diazotized as usual and dissolved in a solution of 38.8 parts of 2,3-oxynaphthoic acid 3'- Pyrenolide (1/10 mol), 100 parts of sodium hydroxide solution of 36 o B6, 15 parts of sodium acetate and 2000 parts of water were introduced. The dye formed precipitates immediately. It is filtered off, washed ge with water and dried.
