Description

  

  Verfahren zur Herstellung eines neuen     bllonoazofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines neuen     Mono-          azofarbstoffes,    dadurch gekennzeichnet, dass  man die     Diazoverbindung    des     1-Äthylbenzoyl-          amitto-4-aminobenzols    mit der     2-Methoxy-          aeetylamino-8-ttaphthol-6-sulfosäure    kuppelt.  



  Der erhaltene Farbstoff stellt ein rotbraunes,  wasserlösliches Pulver dar und färbt die ani  malische Faser in sehr egalen, blaustichig  roten Tönen von sehr guter Schweiss- und  Lichtechtheit.  



  <I>Beispiel:</I>  24 kg     1-Äthylbenzoylamino-4-aminobenzol     werden in üblicher Weise     diazotiert    und die  erhaltene     Diazolösung    wird mit einer Lösung  von 32 kg     2-Methoxyacetylamino-8-naphthol-          6-sulfosäure    unter Zusatz von     Natriumacetat       gekuppelt. Der gebildete Farbstoff wird in  üblicher Weise isoliert und getrocknet.



  Process for the production of a new bllonoazo dye. The present patent relates to a process for the preparation of a new monoazo dye, characterized in that the diazo compound of 1-ethylbenzoylamino-4-aminobenzene is coupled with 2-methoxyethylamino-8-taphthol-6-sulfonic acid.



  The dye obtained is a red-brown, water-soluble powder and dyes the ani malic fiber in very level, bluish red shades of very good fastness to sweat and light.



  <I> Example: </I> 24 kg of 1-ethylbenzoylamino-4-aminobenzene are diazotized in the usual way and the resulting diazo solution is coupled with a solution of 32 kg of 2-methoxyacetylamino-8-naphthol-6-sulfonic acid with the addition of sodium acetate . The dye formed is isolated and dried in the usual way.
