Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass ein neuer     Azo-          farbstoff    hergestellt werden kann, wenn man       diazotiertes        4-(2'-Methyl)-phenoxyacetyl-          amino-2,5-diäthoxy-l-aminobenzol    mit     2,3-          Oxynaphtoesäure-3'-pyrenolid    vereinigt.  



  Der neue     Azofarbstoff    bildet ein blaues,  in Wasser unlösliches Pulver. Auf geeigne  ten Substraten, wie z. B. Baumwolle, her  gestellt, färbt er diese in sehr echten, insbe  sondere auch lichtechten blauen Tönen.         Beispiel     34,6 Teile     4-(2'-Methyl)-phenoxyacetyl-          a.mino-2,5-diäthoxy-l-aminobenzol        (:

  1/1o        Mol)     werden wie üblich     diazotiert    und in eine Lö  sung von 38,8 Teilen     2,3-Oxynaphtoesäure-3'-          pyrenolid        (1/,o        Mol),    100 Teilen     Natrium-          hydroxydlösung    von 36       Be,    15 Teilen Na-         triumacetat    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 prepared if diazotized 4- (2'-methyl) -phenoxyacetylamino-2,5-diethoxy-1-aminobenzene with 2,3-oxynaphthoic acid-3'-pyrenolide united.



  The new azo dye forms a blue, water-insoluble powder. On appro priate substrates such. B. cotton, made ago, he dyes them in very real, in particular special lightfast blue tones. Example 34.6 parts of 4- (2'-methyl) -phenoxyacetyl-a.mino-2,5-diethoxy-1-aminobenzene (:

  1/10 mol) are diazotized as usual and in a solution of 38.8 parts of 2,3-oxynaphthoic acid-3'-pyrenolide (1 /, o mol), 100 parts of sodium hydroxide solution of 36 Be, 15 parts of Na trium acetate and 2000 parts of water. The dye formed precipitates immediately. It is filtered off, washed ge with water and dried.
