Description

  

  Verfahren zur Herstellung eines     ehromierbaren    Farbstoffes.    Gegenstand vorliegenden Patentes ist ein  Verfahren zur     1Ierstell-ung    eines     ehromier-          baren    Farbstoffes. Das Verfahren ist     da-          dureh        gekennzeiehnet,    dass man     diazotiertes        2-          Aniino-l-oxy-lienzol-4-metliyIsulfon    mit.     1-(7-          Oxy-naphthyl)        -carbamidsäure-ätIiy1-g1ykol-          ester    vereinigt..  



  Der     Chromkomplex    des erhaltenen netten  Farbstoffes stellt ein blauschwarzes Pulver  dar,  < las Wolle ans neutralem oder     schwaeh          orgariiseh    saurem Bade in grauen,     hervor-          rao-end        lieliteehten    und     waseheehten    Tönen       iärlit.     



       Beispiel:     Man dianotiert 18,7 Teile     2-Amino-l-oxy-          1>enzol-4-metliylsulfon    und kuppelt nach Neu  tralisieren mit     Natriumbiearbonat    bei 0 bis 5   mit einer Lösung von 28,9 Teilen     1-(7-Oxv-          naplitliyl)-earbamidsäure-äthyl-glykolester,    15  Teilen     wasserfreier    Soda, 4,2 Teilen     Natrium-          hydroxyd    (als     30o/oige        Lösung)    in 200 Teilen  Wasser.

   Nach Beendigung der     Farbstoffbil-          dung    isoliert man den Farbstoff durch Zu  gabe von Kochsalz.    Der Chromkomplex des Farbstoffes kann  erhalten werden, indem man 49,3 Teile seines       hlononatriumsalzes    in 650 Teilen Wasser mit  110 Teilen einer Lösung von     chromsalicyl-          saurem        Ammonium    (entsprechend 4,2 Teilen  Chromoxyd) unter     Rückfluss    zum Sieden er  hitzt, bis die Komplexbildung beendet ist. Es  bildet sich eine dunkelblaue, schleimige Lö  sung, aus der der Chromkomplex durch Zu  gabe von Kochsalz ausgefällt, filtriert und  getrocknet wird.



  Process for the production of an honorable dye. The subject of the present patent is a process for the production of an honorable dye. The process is marked by the fact that diazotized 2-aniino-1-oxy-lienzol-4-methylisulfone is used. 1- (7-Oxy-naphthyl) -carbamic acid-ethyl-glycol ester combined.



  The chromium complex of the nice dye obtained is a blue-black powder, which can be mixed with wool in a neutral or black organic acid bath in gray, excellent white and washed shades.



       Example: 18.7 parts of 2-amino-1-oxy-1> enzene-4-methylsulfone are dianotized and, after neutralization with sodium carbonate at 0 to 5, it is coupled with a solution of 28.9 parts of 1- (7-oxy-naphthyl ) -earbamic acid ethyl glycol ester, 15 parts of anhydrous soda, 4.2 parts of sodium hydroxide (as a 30% solution) in 200 parts of water.

   After the formation of the dye has ended, the dye is isolated by adding sodium chloride. The chromium complex of the dye can be obtained by refluxing 49.3 parts of its hlonosodium salt in 650 parts of water with 110 parts of a solution of chromium salicylic acid ammonium (corresponding to 4.2 parts of chromium oxide) until the complex formation is complete . A dark blue, slimy solution forms from which the chromium complex is precipitated by adding sodium chloride, filtered and dried.
