Description

  

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

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



  Der erhaltene Farbstoff stellt ein dunkel  braunes Pulver dar, das sich in Wasser leicht  mit     bordeauroter    und in konzentrierter  Schwefelsäure mit schmutzig     gelbroter        Farbe     löst. Er färbt vegetabilisch gegerbtes     Leder     in     -,weinroten    und chromgegerbtes Leder in  violett- bis schokoladebraunen 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-          Dioxybenzol    ein Eisen abgebendes Mittel,  dann 1 Mal     diazotierte        4-Chlor-2-amino-l-          phenol-6-sulfonsäure    und hierauf ein Chrom  abgebendes Mittel einwirken     lässt.       <I>Beispiel:

  </I>    31,6 Teile der Eisenverbindung aus     diazo-          tiertem        4-Nitro-2-amino-l-phenol    und     1.3-          Dioxybenzol    werden in 200 Teilen Wasser  und 27 Teilen 30%iger Natronlauge kalt ge  löst, hierauf mit .der neutralisierten     Diazo-          verbindung    aus 22,3 Teilen     4-Chlor-2-amino-          1-phenol-6-sulfonsäure    versetzt und bei 10       bis   <B>18'</B> während 10 bis<B>12'</B> Stunden gerührt.

    Nachdem die Kupplung beendet ist, wird  aufgewärmt, bei<B>70'</B> mit 11,5 Teilen 30 %     iger     Salzsäure, .sowie kochend mit 60     Vol.-Teilen     einer 15,2     Vol.    %     Cr_03    enthaltenden Chrom  sulfatlösung versetzt und 24     Stunden    am       Rückfluss    erhitzt.     Hierauf    lässt man ab  kühlen, fällt .den Farbstoff durch Zugabe  von 120 Teilen Kochsalz aus, filtriert und  trocknet.



      Additional patent to main patent no. 178542. Process for the preparation of a dye containing complexed metal. It has been found that you can produce a complexly bonded metal-containing dye if you 1 mol of @ diazo- tated 4-nitro-2-amino-1-phenol, 1 mol of diazo- tated 4-chloro-2-amino- l-phenol-6-sulfonic acid, 1 mole 1.

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



  The dye obtained is a dark brown powder which dissolves easily in water with a reddish red color and in concentrated sulfuric acid with a dirty yellowish red color. It dyes vegetable-tanned leather in -, wine-red and chrome-tanned leather in real shades of purple to chocolate brown.



  The process can, for example, be carried out in such a way that an iron-releasing agent is applied to the product of 1 mol of diazotized 4-nitro-2-amino-1-phenol and 1 mol of 1,3-dioxybenzene, then 4-chloro-2- amino-1-phenol-6-sulfonic acid and then a chromium-releasing agent can act. <I> example:

  </I> 31.6 parts of the iron compound from diazotized 4-nitro-2-amino-1-phenol and 1,3-dioxybenzene are dissolved cold in 200 parts of water and 27 parts of 30% sodium hydroxide solution, then neutralized with .der Diazo compound of 22.3 parts of 4-chloro-2-amino-1-phenol-6-sulfonic acid was added and at 10 to 18 'for 10 to 12' hours touched.

    After the coupling has ended, the mixture is warmed up, mixed with 11.5 parts of 30% hydrochloric acid at <B> 70 '</B> and, while boiling, with 60 parts by volume of a chromium sulfate solution containing 15.2% by volume of Cr_03 and refluxed for 24 hours. It is then allowed to cool, the dye is precipitated by adding 120 parts of sodium chloride, filtered and dried.
