Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man     diazotiertes          3-Amino-phthalsäure-N-äthylimid    mit dem  2,3 -     Ogynaphthoesäure    - 4'-     chloranilid    ver  einigt.  



  Der neue Farbstoff bildet ein orangerotes,  in Wasser unlösliches Pulver. Auf geeig  neten Substraten, wie z. B. Baumwolle, her  gestellt. färbt er diese in echten orangen  Tönen.  



  <I>Beispiel:</I>  19 Teile des 3 -     Amino    -     phthalsäure    - N     -          äthylimids    werden wie üblich     diazotiert    und  in eine Lösung von 29,7 Teilen     2,3-Ogynaph-          thoesä.ure-4'-chloranilid,    40 Teilen 30 %     iger          Natriumhydrogydlösung,    15 Teilen Soda in    1000 Teilen Wasser eingetragen. Der gebil  dete Farbstoff fällt sofort aus. Der orange  rote Niederschlag wird filtriert und ge  trocknet.



  Process for the production of a new azo dye. It has been found that a new azo dye is obtained if diazotized 3-amino-phthalic acid-N-ethylimide is combined with 2,3 - ogynaphthoic acid - 4'-chloroanilide.



  The new dye forms an orange-red powder that is insoluble in water. On suitable substrates such. B. cotton, made ago. he colors them in real orange tones.



  <I> Example: </I> 19 parts of 3 - amino - phthalic acid - N - ethylimide are diazotized as usual and converted into a solution of 29.7 parts of 2,3-ogynaphthoic acid-4'-chloranilide, 40 Parts of 30% sodium hydrogen solution, 15 parts of soda added to 1000 parts of water. The formed dye precipitates immediately. The orange-red precipitate is filtered and dried.
