Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen     neuen          Azofarbstoff    erhält, wenn man     diazotiertes          z.-    - (4'     -Methyl)        -phenogyacetylamino    - 2 . 5 -     di-          methoxy-l-aminobenzol    mit dem     2-Ogy-2'-          (2)-naphthyl-5.6-pseudonaphthazimid    ver  einigt.  



  Der neue Farbstoff bildet ein braunes, in  Wasser unlösliches Pulver. Auf geeigneten  Substraten, wie z. B. Baumwolle, hergestellt,  färbt er diese in echten braunen Tönen.    <I>Beispiel:</I>    31,6 Teile des     4-(4'-Methyl)-phenogy-          acetylamin    o - 2 . 5 -     dimethogy        -1-aminobenzols     werden wie üblich     diazotiert    und in eine Lö  sung von 31,1 Teilen     2-Ogy-2'-(2)-naphthyl-          5,6-pseudonaphthazimid,    40 Teilen 30%iger       Natriumhydrogydlösung,    15 Teilen Soda und    1000 Teilen Wasser     eingetragen.    Der gebil  dete Farbstoff fällt sofort aus.

   Der     braune     "Niederschlag wird     filtriert    und     getrocknet.  



  Process for the production of a new azo dye. It has been found that a new azo dye is obtained if diazotized z.- (4'-methyl) -phenogyacetylamino-2. 5 - dimethoxy-l-aminobenzene combined with the 2-Ogy-2'- (2) -naphthyl-5.6-pseudonaphthazimide.



  The new dye forms a brown powder that is insoluble in water. On suitable substrates, such as. B. Cotton, he dyes them in real brown tones. <I> Example: </I> 31.6 parts of 4- (4'-methyl) -phenogy-acetylamine o - 2. 5 - dimethogy -1-aminobenzols are diazotized as usual and in a solution of 31.1 parts of 2-Ogy-2 '- (2) -naphthyl-5,6-pseudonaphthazimide, 40 parts of 30% sodium hydrogen hydroxide solution, 15 parts of soda and 1000 parts of water entered. The formed dye precipitates immediately.

   The brown precipitate is filtered off and dried.
