Description

  

      Zusatzpatent    zum Hauptpatent Nr. 178542.    Verfahren zur Herstellung eines     komplex.    gebundenes Metall enthaltenden Farbstoffes.    Es wurde gefunden,     .dass    man einen kom  plex gebundenes Metall enthaltenden     r'arb-          stoff    herstellen kann, wenn man 1     Mol        diazo-          tiertes        4-Nitro-2-amino-l-phenol,    1     Mol        diazo-          tierte        4-Nitro-2-amino-l-phenol-6-sulfonsäure,     1     Mol    1 .

       3-Dioxybenzol    und ein Eisen, sowie  ein Nickel abgebendes Mittel aufeinander  einwirken lässt.  



  Der erhaltene Farbstoff stellt ein in  Wasser mit     olivstichig    brauner Farbe leicht  lösliches, braunschwarzes Pulver dar. Er  färbt aus ameisensaurem Bade vegetabilisch  gegerbtes Leder oder aus neutralem Bade  Chromleder in     gelbstrohig        olivbraunen,    licht  echten Tönen.  



  Das Verfahren kann beispielsweise derart  ausgeführt werden, dass man auf das Ein  wirkungsprodukt aus 1     Mol        diazotiertem          4-Nitro-2-amino-l-phenol    und 1     Mol    1.     3-Di-          oxybenzol    ein Eisen abgebendes Mittel, dann  1     Mol        diazotierte        4-Nitro-2-amino-l-plienol-          6-sulfonsäure    und hierauf ein Nickel     ab-          geberides    Mittel einwirken     lässt.            Beispiel:

       31,6 Teile der Eisenverbindung des Farb  stoffes aus     diazotiertem        4-Nitro-2-amino-l-          pUenol    und 1.     3-Dioxybenzol    werden in 200  Teilen Wasser und 27 Teilen 30 %     iger    Natron  lauge in der Kälte gelöst. und bei 10 bis<B>15'</B>  mit der in üblicher Weise hergestellten und  mit     verdünnter        Sodalösung    neutralisierten       Diazolösung    aus 23,4 Teilen     4-Nitro-2-amino-          1-phenol-6-sulfonsäure    vereinigt. Nach zehn  bis zwölfstündigem Rühren     ist    die Kupplung  beendet.

   Man erwärmt auf<B>50',</B> versetzt mit  11,5 Teilen 30%iger Salzsäure, kocht auf  und setzt eine Lösung von 15,4 Teilen Nickel  sulfat in 60 Teilen Wasser hinzu. Nach zwei  stündigem Kochen am     Rückflusskühler    schei  det man den Farbstoff mit 100 Teilen ab,  filtriert und trocknet bei mässiger Tempe  ratur.



      Additional patent to the main patent No. 178542. Process for the production of a complex. bonded metal containing dye. It has been found that a r'arbstoff containing complex bonded metal can be produced if 1 mol of diazotized 4-nitro-2-amino-1-phenol, 1 mol of diazotized 4-nitro-2 -amino-1-phenol-6-sulfonic acid, 1 mol 1.

       3-Dioxybenzene and an iron, as well as a nickel-releasing agent, can act on one another.



  The dye obtained is a brownish-black powder which is easily soluble in water with an olive-tinged brown color. It dyes vegetable-tanned leather from an acidic bath or chrome leather from a neutral bath in yellow-straw-like, olive-brown, light shades.



  The process can, for example, be carried out in such a way that one mole of diazotized 4-nitro-2-amino-1-phenol and 1 mole of 1,3-dioxybenzene is an iron-releasing agent, then 1 mole of diazotized 4- Nitro-2-amino-1-plienol-6-sulfonic acid and then a nickel-releasing agent can act. Example:

       31.6 parts of the iron compound of the dye from diazotized 4-nitro-2-amino-1-pUenol and 1,3-dioxybenzene are dissolved in 200 parts of water and 27 parts of 30% sodium hydroxide solution in the cold. and at 10 to 15 'with the diazo solution of 23.4 parts of 4-nitro-2-amino-1-phenol-6-sulfonic acid prepared in the usual way and neutralized with dilute soda solution. The coupling is complete after ten to twelve hours of stirring.

   The mixture is heated to 50 ', 11.5 parts of 30% hydrochloric acid are added, the mixture is boiled and a solution of 15.4 parts of nickel sulfate in 60 parts of water is added. After boiling for two hours on the reflux condenser, 100 parts of the dye are separated off, filtered and dried at a moderate temperature.
