Description

  

  Verfahren zur Darstellung eines grünen     substantiven        Trisazofarbstoffes.            Gegenstand    vorliegender Erfindung ist ein  Verfahren zur Darstellung eines grünen     -sub-          stantiven        Baumwolltrisazofarbstoffes,    welches  darauf beruht, dass     1-Naphtalindiazo-4:

  7-di-          sulfosäure    mit     1-Naphtylamin    in saurem  Medium kombiniert, das so gebildete Zwi  schenprodukt     weiterdiazotiert,    die daraus ent  stehende     Diazoazoverbindung    mit     1-m-Aminö-          benzoylamino-8-naphtol.3        #        6-disulfosäure    in al  kalischem     Medium    kombiniert, die so erhal  tene     Disazoverbindung        weiterdi:

  izotiert    und  die daraus erhaltene     Diazodisazoverbindung     mit     1-Phenyl-3-methyl-5-pyi#azolon    in alka  lischem     Medium    kombiniert wird.  



  <I>Beispiel:</I>  32,5 Teile     1-Aminonaphtalin-4:7-disulfö-          säure        (Monoriatriumsalz)    werden     diazotiert     und in salzsaurer Lösung mit 15 Teilen       1-Naphtylamiri    kombiniert. Man lässt dann  eine Lösung von 7,5 Teilen     Natriumnitrit      zulaufen.

   Man salzt die     Diazoverbindung    aus,    filtriert sie ab, rührt sie mit Wasser an und  lässt sie unter     Kühlung    in eine     sodaalkalische     Lösung von 40 Teilen     1-m-Amiriobenzoyl-          aminö-8-naphtöl-3        #        6-disulfosäurefliessen.Nach     erfolgter Kombination salzt man den.

   blauen       Disazofarbstoff    warm aus, löst ihn in Wässer  und     diazotiert    ihn bei gewöhnlicher     Tewpe-          ratur    in der üblichen Weise mit Salzsäure  und Nitrit und nimmt die     Kombination    mit  7,5 Teilen     1-Phenyl-3-methyl-5-pyrazolon    in       sodaälkalischer    Lösung bei niederer Tem  peratur vor, worauf der Baumwolle grünfär  bende fertige Farbstoff aasgesalzen wird.



  Process for the preparation of a green substantive trisazo dye. The present invention relates to a process for the preparation of a green -sub- stantiven cotton trisazo dye, which is based on the fact that 1-naphthalene-diazo-4:

  7-disulfonic acid combined with 1-naphthylamine in an acidic medium, the intermediate product formed in this way is further diazotized, the resulting diazoazo compound is combined with 1-m-aminobenzoylamino-8-naphthol.3 # 6-disulfonic acid in an alkaline medium, continue the disazo connection obtained in this way:

  izotiert and the diazodisazo compound obtained therefrom is combined with 1-phenyl-3-methyl-5-pyi # azolone in an alkaline medium.



  <I> Example: </I> 32.5 parts of 1-aminonaphthalene-4: 7-disulphoic acid (monoriatic salt) are diazotized and combined with 15 parts of 1-naphthylamine in a hydrochloric acid solution. A solution of 7.5 parts of sodium nitrite is then allowed to run in.

   The diazo compound is salted out, filtered off, stirred with water and allowed to flow into a soda-alkaline solution of 40 parts of 1-m-amiriobenzoylamino-8-naphthoil-3 # 6-disulfonic acid while cooling. After the combination is complete, it is salted the.

   warm blue disazo dye, dissolves it in water and diazotizes it at ordinary temperature in the usual way with hydrochloric acid and nitrite and takes the combination with 7.5 parts of 1-phenyl-3-methyl-5-pyrazolone in a solution of soda alkaline at lower Tem perature, whereupon the cotton green-colored finished dye is carrion salt.
