Description

  

  Verfahren zur Herstellung eines neuen     3ionoazofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines neuen Mono  azofarbstoffes, dadurch gekennzeichnet, dass  man die     Diazoverbindung    von     1-Methoxy-          acetyl-4-aminobenzol    mit der     1-Naphthol-          3.6-dis(ilfosäure    kuppelt.  



  Der erhaltene Farbstoff stellt ein dunkel  rotes wasserlösliches Pulver dar und färbt  die animalische Faser in egalen, lichtechten,  roten Tönen.  



  <I>Beispiel</I>  28 kg     1-Methoxyacetyl-4-aminobenzol     werden in üblicher Weise dianotiert, und die  erhaltene     Diazolösung    wird mit einer     soda-          alkalischen    Lösung von 31 kg     1-Naphthol-          3.6-disulfosäure    gekuppelt. Der erhaltene    Farbstoff wird in üblicher Weise isoliert und  getrocknet.



  Process for the preparation of a new 3ionoazo dye. The present patent relates to a process for the preparation of a new mono azo dye, characterized in that the diazo compound of 1-methoxyacetyl-4-aminobenzene is coupled with 1-naphthol-3,6-dis (ilfoic acid.



  The dye obtained is a dark red, water-soluble powder and dyes the animal fiber in level, lightfast, red shades.



  <I> Example </I> 28 kg of 1-methoxyacetyl-4-aminobenzene are dianotized in the usual way, and the diazo solution obtained is coupled with a soda-alkaline solution of 31 kg of 1-naphthol-3,6-disulfonic acid. The dye obtained is isolated and dried in the usual way.
