Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.            Es        wurde    gefunden, dass man einen     neuen          Azofarbstoff        erhält,    wenn man     diazotierten          p-Chlorphenylester    der     2-Aminobenzoesäure     mit dem     2-Methogyanilid    der     2,3-OOgynaph-          thoesäure    vereinigt. Der neue Farbstoff stellt  einen orangen Niederschlag dar.

   Auf geeig  neten Substraten,     wie    zum     Beispiel    Baum  wolle, hergestellt, färbt er diese in orangen  Tönen mit vortrefflichen Echtheitseigen  schaften.  



  <I>Beispiel:</I>       24;8    Teile     des        p-Chlorphenylesters    der       2-Aminobenzoesäure    werden wie üblich     dia-          zotieit    und in eine     Lösung    von     293    Teilen       2,3-Ogynaphthoesäure-2'-methogyanilid,    50  Teilen 30 %     iger    Natronlauge, 80 Teilen Soda         und    2000     Teilen    Wasser     eingetragen.    Der       gebildete    Farbstoff fällt sofort aus.

   Der  orange 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 p-chlorophenyl ester of 2-aminobenzoic acid is combined with the 2-methogyanilide of 2,3-O-gynaphthoic acid. The new dye is an orange precipitate.

   Manufactured on suitable substrates such as cotton, he dyes them in orange tones with excellent authenticity properties.



  <I> Example: </I> 24; 8 parts of the p-chlorophenyl ester of 2-aminobenzoic acid are diazotieit as usual and in a solution of 293 parts 2,3-ogynaphthoic acid-2'-methogyanilide, 50 parts 30% Sodium hydroxide, 80 parts of soda and 2000 parts of water entered. The dye formed precipitates immediately.

   The orange precipitate is filtered and dried ge.
