Description

  

  Verfahren zur Herstellung eines neuen     Azofarüstoffes.       Es wurde     gefunden,    dass ein neuer     Azo-          farbstoff    hergestellt werden kann, wenn  man     dia.zotiertes        1-Amino-2-methyl-4-nitro-          benzol    mit     2,3-Oxynaphthoesäure-3'-pyrenolid     vereinigt.  



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



  <I>Beispiel</I>       1.ä,9    Teile     1-Amino-2-methyl-4-nitro-          benzol        (1/1a        142o1)    werden wie üblich     diazo-          tiert    und in eine Lösung von 38,8 Teilen       2,3-Oxynaphthoesäure-3'-pyrenolid        ('/1o    Hol),  <B>100</B> Teilen     Natriumhydroxydlösung    von       36   <I> </I>     Be,   <B>15</B> Teilen     Natriumacetat    und 2000    Teilen Wasser     eingetragen.    Der gebildete  Farbstoff fällt sofort aus.

   Er wird     abfil-          triert,    mit Wasser gewaschen     und    getrocknet.



  Process for the production of a new azo fuel. It has been found that a new azo dye can be produced by combining dia.zotierter 1-amino-2-methyl-4-nitro-benzene with 2,3-oxynaphthoic acid-3'-pyrenolide.



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



  <I> Example </I> 1.ä, 9 parts of 1-amino-2-methyl-4-nitrobenzene (1 / 1a 142o1) are diazotized as usual and in a solution of 38.8 parts of 3-oxynaphthoic acid-3'-pyrenolide ('/ 1o Hol), <B> 100 </B> parts of sodium hydroxide solution of 36 <I> </I> Be, <B> 15 </B> parts of sodium acetate and 2000 parts of water registered. The dye formed precipitates immediately.

   It is filtered off, washed with water and dried.
