Description

  

  Verfahren zur Herstellung eines     Honoazofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Monoazofarb-          stoffes,    dadurch gekennzeichnet, dass man die       Diazoverbindung    von     1-Cyklohexylmetboxy-          acetylamino-4-aminobenzol    mit     1-(2'-Methyl-          phenoxyacetylamirio)        -8-naphthol-4    .     6-disulfo-          säure    kuppelt.  



  Er bildet ein rotes wasserlösliches Pulver,  das Wolle und Seide in leuchtenden roten  Tönen von sehr guter Seewasser-, Schweiss-,  Walk- und Lichtechtheit färbt.  



  <I>Beispiel:</I>  26 kg     1-Cyklohexylmethoxyacetylamino-          4-aminobenzol    werden     diazotiert.    Die erhal  tene     Diazolösung    lässt man in eine über  schüssige Soda enthaltende Lösung von 48 kg  1-(2'-Methylphenoxyacetylamino)-8-naphthol-         4.6-disulfosäure    laufen. Der so erhaltene  Farbstoff wird durch Anwärmen und     Aussal-          zen    isoliert, filtriert und getrocknet.



  Process for the preparation of a honoazo dye. The present patent relates to a process for the preparation of a monoazo dye, characterized in that the diazo compound of 1-cyclohexylmetboxyacetylamino-4-aminobenzene is mixed with 1- (2'-methylphenoxyacetylamirio) -8-naphthol-4. 6-disulfonic acid couples.



  It forms a red, water-soluble powder that dyes wool and silk in bright red shades of very good seawater, sweat, milled and lightfastness.



  <I> Example: </I> 26 kg of 1-cyclohexylmethoxyacetylamino-4-aminobenzene are diazotized. The diazo solution obtained is poured into a solution of 48 kg of 1- (2'-methylphenoxyacetylamino) -8-naphthol-4,6-disulfonic acid containing excess soda. The dyestuff obtained in this way is isolated by heating and salting out, filtered and dried.
