Description

  

  Verfahren zur Herstellung     eines        Nonoazofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Monoazo-          farbstoffes,    dadurch gekennzeichnet, dass man       diazotiertes        m-Aminobenzoyl-di-n-butylamin     in     sodaalkalischem    Medium mit     1-(2'-DZethyl-          phenoxy-acetylamino)-8-naphthol-4.    6     -disulfo-          säure    kuppelt.  



  Der neue Farbstoff stellt nach dem Trock  nen ein rotes, wasserlösliches Pulver dar und  färbt Wolle und Seide in lebhaften roten  Tönen von sehr guter Wasch.,     Walk-,    Schweiss-,  Seewasser- und Lichtechtheit.    <I>Beispiel:</I>    24,8 Teile     m-Aminobenzoyl-di-n-butylamin     werden in der üblichen Weise     diazotiert.    Die  erhaltene     Diazolösung    lässt man zu einer mit  überschüssiger Soda versetzten Lösung von  47 Teilen 1-(2'-Methyl-phenogy-acetylamino)-         -8-naphthol-4.6-disulfosäure    laufen. Nach be  endeter Kupplung wird der gebildete Farb  stoff isoliert und getrocknet.



  Process for the preparation of a nonoazo dye. The present patent relates to a process for the preparation of a monoazo dye, characterized in that diazotized m-aminobenzoyl-di-n-butylamine in a soda-alkaline medium with 1- (2'-DZethyl-phenoxy-acetylamino) -8-naphthol- 4th 6 -disulfonic acid couples.



  After drying, the new dye is a red, water-soluble powder and dyes wool and silk in vivid red tones with very good wash, milled, sweat, seawater and lightfastness. <I> Example: </I> 24.8 parts of m-aminobenzoyl-di-n-butylamine are diazotized in the usual way. The resulting diazo solution is allowed to run into a solution of 47 parts of 1- (2'-methyl-phenogy-acetylamino) - -8-naphthol-4,6-disulfonic acid, to which excess soda is added. After the coupling has ended, the dye formed is isolated and dried.
