Description

  

  Verfahren zur Herstellung eines sauren     Wollazofarbstoffes.            Vorliegendes    Patent bezieht sich auf ein  Verfahren zur     Herstellung        eines    sauren       Wollazofarbstoffes,    dadurch     gekennzeichnet,          dass        man,diazotiertes        1-(N-Acetyl-sec.-butyl-          amino)-4-aminobenzol        in    essigsaurem     Medium     mit     1-Benzoylamino-5-naphthol-7=s.ulfosäume     kuppelt.  



  Der so erhaltene Farbstoff     bildet    nach  dem Trocknen ein ziegelrotes, wasserlösliches  Pulver und färbt Wolle und Seide in leb  haften     gelbstichigroten    Tönen von sehr       gutem        Egalisiervermögen    und     guten    Echt  heitseigenschaften.  



  <I>Beispiel:</I>  20,6     Teile        1-(N-Aoetyl-sec.-buty1,amino)-          4-aminobenzol    werden     in.    der     üblichen    Weise       ,diazotiert.    Die erhaltene     Diazolösung    lässt  man in eine mit     überschüssigem    Natrium  acetat versetzte Lösung von<B>36,</B> Teilen         1-Benzoylamino-5-naphthol-7-sulfonsäure    ein  laufen. Nach beendeter Kupplung     wird    der  Farbstoff abgeschieden und     ,getrocknet.  



  Process for the preparation of an acidic wool azo dye. The present patent relates to a process for the preparation of an acidic wool azo dye, characterized in that diazotized 1- (N-acetyl-sec.-butyl-amino) -4-aminobenzene in acetic acid medium with 1-benzoylamino-5-naphthol- 7 = s.ulfo seams domes.



  The dye thus obtained forms a brick-red, water-soluble powder after drying and dyes wool and silk in lively yellow-tinged red shades with very good leveling properties and good fastness properties.



  <I> Example: </I> 20.6 parts of 1- (N-aoetyl-sec.-buty1, amino) -4-aminobenzene are diazotized in the usual way. The diazo solution obtained is poured into a solution of 36 parts of 1-benzoylamino-5-naphthol-7-sulfonic acid to which excess sodium acetate has been added. After the coupling has ended, the dye is deposited and dried.
