Description

  

  Verfahren zur Herstellung eines neuen     Honoazofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines neuen Mono  azofarbstoffes, dadurch gekennzeichnet, dass  man die     Diazoverbindung    des     1-Metboxy-          acetyl-cyclohexylamino-4-aminobenzols    mit  der     1-Acetylamino-8-naphthol-4.6-disulfo-          säure    kuppelt.  



  Der erhaltene     Farbstoff    stellt ein rotes  wasserlösliches Pulver dar und färbt die  animalische Faser in egalen, leuchtend roten  Tönen von sehr guter Wasch-, Schweiss- und  Lichtechtheit.  



  <I>Beispiel:</I>  26,2 kg     1-Methoxyacetyl-cyclohexylamino-          4-aminobenzol    werden in üblicher Weise       diazotiert    und die erhaltene     Diazolösung     wird mit einer     sodaalkalischen    Lösung von  <B>87</B> kg 1-Acetylamino-8-naphthol-4.6-disulfo-         säure    gekuppelt. Der gebildete Farbstoff wird  in üblicher Weise isoliert und getrocknet.



  Process for the production of a new honoazo dye. The present patent relates to a process for the production of a new mono azo dye, characterized in that the diazo compound of 1-metboxy-acetyl-cyclohexylamino-4-aminobenzene is coupled with 1-acetylamino-8-naphthol-4,6-disulphonic acid.



  The dye obtained is a red, water-soluble powder and dyes the animal fibers in level, bright red shades of very good fastness to washing, perspiration and light.



  <I> Example: </I> 26.2 kg of 1-methoxyacetyl-cyclohexylamino-4-aminobenzene are diazotized in the usual way and the diazo solution obtained is mixed with a soda-alkaline solution of <B> 87 </B> kg of 1-acetylamino- 8-naphthol-4,6-disulfonic acid coupled. The dye formed is isolated and dried in the usual way.
