Description

  

  Verfahren zur Herstellung eines     Monoazofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Monoazofarb-          stoffes,    dadurch gekennzeichnet, dass man die       Diazoverbindung    von 1 -     Cyklohexylacetyl-          amino-4-aminobenzol    mit     1-(p-Methylphenoxy-          acetylamino)-8-naphthol-4.        6-disulfosäure    kup  pelt.  



  Er bildet ein rotes wasserlösliches Pulver  und färbt Wolle aus saurem Bade in sehr  klaren scharlachroten Tönen von sehr guter  Seewasser-, Schweiss-, Walk- und Lichtecht  heit.    <I>Beispiel:</I>    23,2 kg     1-Cyklohexylacetylamino-4-amino-          benzol    werden in üblicher Weise     diazotiert.     Die erhaltene     Diazolösung    lässt man in eine  überschüssige Soda enthaltende Lösung von  48 kg 1-(p-Methylphenoxyacetylamino)-8-         naphthol-4.6-disulfosäure    laufen. Der so er  haltene Farbstoff wird isoliert und getrocknet.



  Process for the preparation of a monoazo dye. The present patent relates to a process for the preparation of a monoazo dye, characterized in that the diazo compound of 1-cyclohexylacetylamino-4-aminobenzene is mixed with 1- (p-methylphenoxyacetylamino) -8-naphthol-4. 6-disulfonic acid coupling.



  It forms a red water-soluble powder and dyes wool from an acid bath in very clear, scarlet shades that are very fast to sea water, perspiration, fulling and light. <I> Example: </I> 23.2 kg of 1-cyclohexylacetylamino-4-aminobenzene are diazotized in the usual way. The diazo solution obtained is poured into a solution of 48 kg of 1- (p-methylphenoxyacetylamino) -8-naphthol-4,6-disulfonic acid containing excess soda. The dye obtained in this way is isolated and dried.
