Description

  

      Verfahren    zur Herstellung eines metallhaltigen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen  metallhaltigen     Farbstoff    erhält, wenn man  den chromhaltigen     Farbstoff,    der durch Be  handlung des     Azofarbstoffes    aus der nitrierten       1-Diazo-2-oxynaphtalin-4-sulfosäure    und ss  Naphthol mit     Chromformiat    in der Wärme  und in . Gegenwart von     Natriumacetat    ent  steht, mit Kupfersalzen behandelt.  



  Der neue     Farbstoff    ist in Wasser mit       violettschwarzer,    in 10     o/oiger    Natronlauge       mit'rötlich    braunvioletter und in konzentrierter  Schwefelsäure mit blauer Farbe löslich. Er  färbt Wolle und Seide in schwarzen Tönen an.

    <I>Beispiel:</I>  Die nach dem Beispiel der Patentschrift  Nr.<B>130155</B> erhältliche Lösung der Chrom  verbindung des     Azofarbstoffes    aus der nitrier  ten     Diazoverbindung    der     1-Amino-2-oxynaph-          talin-4-sulfosäure    und     f-Naphtol    wird vor  dem Aussahen mit einer konzentrierten Lö  sung von 25 Teilen Kupfersulfat, sowie 30    Teilen kristallisiertem     Natriumacetat    versetzt  und zwei Stunden bei 50-60o gerührt, wo  rauf nach dem Filtrieren der     Farbstoff    durch       Aussalzen    abgeschieden wird.



      Process for the preparation of a metal-containing azo dye. It has been found that a new metal-containing dye is obtained if the chromium-containing dye, which is obtained by treating the azo dye from the nitrated 1-diazo-2-oxynaphthalene-4-sulfonic acid and ss naphthol with chromium formate in the heat and in. The presence of sodium acetate is treated with copper salts.



  The new dye is soluble in water with violet-black, in 10% sodium hydroxide solution with reddish brown-violet and in concentrated sulfuric acid with blue color. He dyes wool and silk in black tones.

    <I> Example: </I> The solution of the chromium compound of the azo dye from the nitrated diazo compound of 1-amino-2-oxynaphthalene-4-, which can be obtained according to the example of patent specification no. Sulphonic acid and f-naphthol is mixed with a concentrated solution of 25 parts of copper sulphate and 30 parts of crystallized sodium acetate and stirred for two hours at 50-60o, where up after filtration the dye is deposited by salting out.

PATENTANSPRUCH: Verfahren zur Herstellung eines metall haltigen Azofarbstoffes, dadurch gekennzeich net, dass man den chromhaltigen Farbstoff, der durch Behandlung des Azofarbstoffes aus der nitrierten 1-Diazo-2-oxynaphtalin-4-sulfo- säure und ss-Naphtol mit Chromformiat in der Wärme und in Gegenwart von Natrium acetat entsteht, mit Kupfersalzen behandelt. PATENT CLAIM: Process for the production of a metal-containing azo dye, characterized in that the chromium-containing dye, which is obtained by treating the azo dye from the nitrated 1-diazo-2-oxynaphthalene-4-sulfonic acid and ss-naphthol, is heated with chromium formate and in the presence of sodium acetate is formed, treated with copper salts. Der neue Farbstoff ist in Wasser mit violettschwarzer, in 10 o/oiger Natronlauge mit rötlich braunvioletter und in kon zentrierter Schwefelsäure mit blauer Farbe löslich. Er färbt Wolle und Seide in schwar zen Tönen an. The new dye is soluble in water with violet-black, in 10% sodium hydroxide solution with reddish brown-violet and in concentrated sulfuric acid with blue color. He dyes wool and silk in black tones.
