Description

  

      VerAhren    zur Darstellung eines     grÜneu        substantiven        Trisazofarbstoffes.       Gegenstand vorliegender Erfindung ist  ein Verfahren zur Darstellung eines grünen       substantiven        Baumwolltrisazofarbstoffs,    wel  ches darauf beruht.

       dass        2-Naphtalindiazo-          4        -8-disulfosäure    mit     i-Naphtylamin    in sau     -          rem    Medium kombiniert, das so gebildete  Zwischenprodukt weiter     diazotiert,    die dar  aus entstehende     Diazoazoverbindung    mit<B>1-</B>       ni-Aminobenzoylamino-8-naphtol-3-6-disulfo-          säure    in alkalischem Medium kombiniert,

    die so erhaltene     Disazoverbindung    weiter       diazotiert    und die daraus erhaltene     Diazo-          disazoverbindung    mit     1-Phenyl-3-methyl-5-          pyrazolon    in alkalischem Medium kombi  niert wird.  



  <I>Beispiel:</I>  <B>32,5</B> Teile     2-Naphtylamin-4-8-disulfosäure          (Mononatriumsalz)    werden     diazotiert    und in.  salzsaurer Lösung mit<B>15</B> Teilen     1-Naplityl-          amin    kombiniert.

   Man     lässt    dann eine     IA-          sung    von<B>7,5</B> Teilen     Natriumnitrit    zulaufen,  Man salzt die     Diazoverbindung    aus, filtriert  sie ab, rührt sie mit Wasser an und     lässt       sie     unCer    Kühlung in eine     sodaalkalische     Lösung von     40    Teilen     1-ni-Aminobenzoyl-          amino-S-iiapittol-3-6-clisulfosäure    fliessen.

    Nach erfolgter Kombination salzt man den  blauen     Disa.zofarbstoff    warm aus, löst ihn in  Wasser und     diazotiert    ihn bei gewöhnlicher  Temperatur in der Üblichen Weise mit Salz  säure und Nitrit und nimmt die     Kornbina-          tion    mit<B>17,3</B> Teilen     1-Plienyl-3-methyl-5-          pyrazolon        in        sodaalkalischer    Lösung bei nie  derer Temperatur vor, worauf der Baum  wolle grün färbende, fertige Farbstoffe     aus-          gesalzen    wird.



      Process for the representation of a green substantive trisazo dye. The present invention is a process for preparing a green substantive cotton trisazo dye based thereon.

       that 2-naphthalene-diazo-4-8-disulfonic acid is combined with i-naphthylamine in an acidic medium, the intermediate product thus formed is further diazotized, the resulting diazoazo compound with 1- ni-aminobenzoylamino-8-naphtol -3-6-disulphonic acid combined in an alkaline medium,

    the disazo compound thus obtained is further diazotized and the diazo disazo compound obtained therefrom is combined with 1-phenyl-3-methyl-5-pyrazolone in an alkaline medium.



  <I> Example: </I> <B> 32.5 </B> parts of 2-naphthylamine-4-8-disulfonic acid (monosodium salt) are diazotized and mixed with <B> 15 </B> parts of 1 in hydrochloric acid solution -Naplitylamine combined.

   A solution of 7.5 parts of sodium nitrite is then run in. The diazo compound is salted out, filtered off, stirred with water and allowed to cool in a soda-alkaline solution of 40 parts 1 -ni-aminobenzoyl-amino-S-iiapittol-3-6-clisulfonic acid flow.

    After the combination has taken place, the blue disa.zo dye is salted out warm, dissolved in water and diazotized at normal temperature in the usual way with hydrochloric acid and nitrite and the combination is made up of <B> 17.3 </B> parts 1-plienyl-3-methyl-5-pyrazolone in a soda-alkaline solution at a low temperature, whereupon the cotton is salted out, ready-to-use dyes that turn green.
