Description

  

  Verfahren zur Herstellung eines     Monoazofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     DZonoazofarb-          stoffes,        dadureh    gekennzeichnet, dass man die       Diazoverbindung    von     1-n-Butylacetylamino-          4-aminobenzol    mit     1-(2'-Chlorpbenogyacetyl-          ainino)-8-naphthol-4.6-disulfosäure    kuppelt.  



  Er bildet ein rotes wasserlösliches Pulver,  das Wolle und Seide in leuchtenden Schar  lachtönen von sehr guter Wasch-, Walk- und  Lichtechtheit färbt.  



       Beispiel:     20,6 kg     1-n-Butylacetylamiiro-4-amino-          benzol    werden dianotiert. Die erhaltene     Diazo-          lösung    lässt man in eine überschüssige Soda  enthaltende Lösung von 50 kg     1-(2'-Chlor-          pherio%yacetylamino)-8-n        aphthol    - 4 . 6 -     disulfo-          aäure    laufen. Der so erhaltene Farbstoff wird    durch Anwärmen und     Aussalzen    isoliert, fil  triert und getrocknet.



  Process for the preparation of a monoazo dye. The present patent relates to a process for the preparation of a D-zonoazo dye, characterized in that the diazo compound of 1-n-butylacetylamino-4-aminobenzene is mixed with 1- (2'-chloropbenogyacetyl-ainino) -8-naphthol-4,6-disulphonic acid clutch.



  It forms a red, water-soluble powder that dyes wool and silk in brilliant shades of laughing shades of very good wash, milled and lightfastness.



       Example: 20.6 kg of 1-n-butylacetylamiiro-4-aminobenzene are dianotized. The diazo solution obtained is immersed in a solution of 50 kg of 1- (2'-chloropherio% yacetylamino) -8-naphthol -4 containing excess soda. 6 - run disulfo acid. The dye obtained in this way is isolated by heating and salting out, filtered and dried.
