Description

  

  Verfahren zur Herstellung eines<B>komplex</B> gebundenes Chrom  enthaltenden     Azofarbstoffes.       Es wurde gefunden,     dass    ein komplex ge  bundenes Chrom enthaltender     Azofarbstoff     hergestellt werden kann, wenn der     Azofarb-          stoff    aus<B>1</B> M     ol        diazotierter        2-Amino-l-oxy-          6-earboxybenzol-4-sulfonsäure   <B>und 1</B>     Mol        5-          Oxyperinaplithindandion    mit     eli-romabgeben-          den    Mitteln behandelt wird.

    



  Die neue Chromverbindung stellt ein  graues Pulver dar, das sieh in Wasser, in  10%iger     Sodalösung    und in 10%iger Na  tronlauge mit     braunoranger,    in konzentrierter  Schwefelsäure mit     olivbrauner    Farbe löst.  Sie erzeugt auf Leder braunviolette Töne von  guten Echtheitseigenschaften.  



  Der dem     Veziahren    als     Ausgangsstoff     dienende     Azofarbstoff    kann durch Kupplung  in alkalischem Medium von     äquiniolekularen     Mengen     diazotierter        2-Amino-l-oxy-6-earb-          oxybenzol-4-sulfonsäure    und     5-Oxyperinaph-          thindandion    erhalten werden.  



  Die     Behandung    mit     ehromabgebenden     Mitteln erfolgt     nac'h    den bekannten Me-         thoden,    beispielsweise durch Erhitzen in wäs  seriger Lösung mit Salzen des dreiwertigen  Chroms.  



       Beispiel:     45,6 Teile des     Azofarbstoffes    aus     diazo-          tierter        2-Amino-l-oxy-6-earboxybenzol-4-sul-          fonsäure    und     5-Oxyperinaphthindandion    wer  den in<B>1000</B> Teilen Wasser gelöst und mit  einer     Fluorellromlösung,    enthaltend<B>9,1,</B> Teile       r,O"    24 Stunden zum Sieden erhitzt. Man  gewinnt die neue Chromverbindung durch  Beigabe von Kochsalz, Filtrieren und Trock  nen.



  Process for the production of an azo dye containing <B> complex </B> bound chromium. It has been found that an azo dye containing complexly bound chromium can be produced if the azo dye is composed of 1 mol of diazotized 2-amino-1-oxy-6-earboxybenzene-4-sulfonic acid > and 1 </B> mol of 5-oxyperinaplithindandione is treated with eli-rom-releasing agents.

    



  The new chromium compound is a gray powder that dissolves in water, in 10% sodium carbonate solution and in 10% sodium hydroxide solution with brown-orange, in concentrated sulfuric acid with an olive-brown color. It produces brown-violet tones with good fastness properties on leather.



  The azo dye used as the starting material for the process can be obtained by coupling in an alkaline medium equine molecular amounts of diazotized 2-amino-1-oxy-6-oxybenzene-4-sulfonic acid and 5-oxyperinaphthindanedione.



  The treatment with blood-releasing agents takes place according to the known methods, for example by heating in an aqueous solution with salts of trivalent chromium.



       Example: 45.6 parts of the azo dye from diazotized 2-amino-1-oxy-6-earboxybenzene-4-sulfonic acid and 5-oxyperinaphthindanedione are dissolved in 1000 parts of water and mixed with a Fluorellromium solution containing <B> 9.1, </B> parts r, O "heated to boiling for 24 hours. The new chromium compound is obtained by adding sodium chloride, filtering and drying.
